The ideal aesthetic treatment would be something that looks aesthetically pleasing in the patient’s mouth without any excessive standout statements. It may reside in the patient’s mouth rather subtly from a third person’s point of view, but I believe that a beautiful restoration would nonetheless have a dramatic impact on the patient.A dentist and a technician strive for a common goal from the clinical diagnosis to the seating of the definitive restoration. Labline is a magazine remarkable for publishing educational articles with many beautiful pictures and for its page design. At the same time it is an enjoyable read for all dental professionals. I hope Labline will stay a valuable asset to the readers’ daily clinical practice for a long time.

INTERVIEW WITH MDT. PAULO BATTISTELLA

Oh, Paulo Battistella is just an ordinary person. I think it is very important to say this. I am a normal person. I have dreams. I have a philosophy of life. I have a focus in how I do all my projects. My mind is working all the time in order to inspire me to inspire others as well.
spot Focus on what you want to achieve in your career!!! I am a very sensitive person. Sometimes it just comes like an inspiration out of nowhere. Something comes into my mind and I start doing it. I think it just comes naturally.
DR. CLAUDIA VOLPATO et.al. - CERAMICS AND ESTHETIC QUALITY

Traditionally, ceramics used as veneering materials and ceramic veneers are the feldspath-based material. Latest versions based on f luorapatite-leucite have been used for the same purpose, with excellent esthetic results. However, regardless of the used layering material , for the cl inical and technical procedures to be predictable, it is important that an excellent diagnostic wax-up be performed previously and thoroughly tested in the mouth by a diagnostic mock-up.
spot The technique allows to assess and control the depth of the preparat ion and faci l itate ceramic strat i ficat ion, since the dental technician has tested the dental shape previously in wax. In this case report, a ceramic crown and three veneers were made with a glass-ceramic based on fluorapatite-leucite. The surgical* and prosthetic s teps a re presented below.
JOSHUA POLANSKY - A TECHNICIANS JOURNEY

Mastering any skill is a timeless journey. There is no difference in mastering the art of fine watch making dating back to the 1800s and mastering dental technology today. It requires equal parts of passion, discipline, curiosity, resilience, and pain. Depending on how you approach your skill set will determine the end vision of what you are trying to achieve.
spot The magic happens on that journey, not necessarily the end vision. The following article is a visual inventory into my personal journey with dentistry and how I achieved passion, love, desire, pain, success, and failure all through the simple study of teeth.
DT. ALEK ARONIN - BONDED ¾ CROWNS AND PARTIAL VENEER

As we know, bonded restoration is usually used in non-invasive dentistry. But in this case, we used this type of restoration in order to keep the substructure of the traumatized teeth and provide an aesthetic result in the interior region.
spot The patient is a 12 years old boy who fell off his scooter. Teeth 11 and 21 were luxated palatal, medial corners of 11, 21 and 22 were broken furthermore the
centrals were oozing blood from the sulcus. After a couple of months of treatment and temporalization, the teeth were stable, asymptomatic and in full occlusion. We decided to go with bonded porcelain restoration.
DR. MARCO MAIOLINO - THE SINGLE VENEER CHALLENGE

It is a common experience among both dentists and dental technicians that the most challenging situation we have to face in our work is the restoration of a single tooth between healthy natural teeth. This is usually the greatest challenge of our profession. You cannot play, as it happens, with six veneers or crowns to produce a mimetic restoration. Natural teeth are there to stay and your work has to fit that space perfectly.
spot In these situations my first choice is the feldspathic veneer. In my opinion, it is the restoration that most easily blends with the natural neighboring teeth thanks to its contact lens feature and its optical and physical characteristics. The task is easier if we have to deal with cases like a small trauma where the remaining tooth substrate is the same color as the neighboring teeth.
DR. SAID SANCHEZ et. al. - PROSTHETIC REHABILITATION OF THE EDENTULOUS PATIENT

The prosthetic rehabilitation of the edentulous patient with implant overdentures has many advantages in comparison to conventional tissue-supported dentures in terms of retention, stability and chewing efficiency, resulting in high patient satisfaction. However, proper diagnosis and treatment planning are critical to obtain successful results.
spot Factors such as the number and distribution of implants, abutment selection, superstructure design, type of occlusion and opposing dentition are key aspects in the treatment planning of implant-retained overdentures. This clinical report describes in a systematic sequence the diagnosis, treatment planning and surgical prosthetic management in the rehabilitation of a completely edentulous patient using dental implants and a removable prosthesis personalized with pink composite.
RAFAEL SANCHEZ, DR. LARRY GRILLO - UPPER RECONSTRUCTION USING SCOOP TECHNIQUE

The restoration of a full upper arch with a combination of crowns and the restoration of the posterior lower arch.

RODRIGO MONSANO - READING OF NONEXISTENT COLOR

In this article the challenge of reproducing unitary central incisors will be discussed. Consider the literal meaning of units: unique, because they are individual, peculiar in their characteristics and thus impossible to establish a rigid prescription that applies to all cases, here is the premise that each case is a case. This makes it fundamental to understand the variables that can influence the result when reproducing unitary teeth.
spot Color scales are widely used and are applied to present a reference in the standardization of ochres so that it is possible to communicate the color and even an initial reference when you do not know where to start. Although the spectrophotometers are good instruments to work with, they are still ancillary in color reading, their functioning mechanism consists of the transmission of light that interacts with the object and returns to the instrument.

After beginning a new year, it is usually the time to reflect on the past year and look towards the new one. The question will be left where we will be going in our profession and what kind of changes in the dental field we will face. New innovations and techniques will be presented at the IDS in March and tendencies will be shown as a barometer for all of us. Investments might have to be made or strategies might have to be developed specifically in terms of communication and digital workflow. We seem to be in an unbridled period of time concerning networking and global connection. Is that a kind of blessing or rather a pressure with the danger of losing our identity as craft-minded professionals? I believe the answer is somewhere in the middle as usual. Material releases and associated innovations, very often push us to a higher level with better and easier results and longevity.

INTERVIEW WITH MDT. NAOKI HAYASHI

I am a dental technician and I always “play” with “dental”. Most of the dental technicians think that this is just a job, but for me, Naoki Hayashi, this is my life. I am a perfectionist and sometimes I don’t like this about myself. When I meet the dentists and the patients or when I give a lecture or a presentation, I want to have perfect cases to show perfect photos, the perfect presentation design and perfect movies.
spot My priority is the patient. The dental technician cannot make everything, but I think we can help the patient a little bit. I want to produce a restoration without the smallest imperfection. I believe it is completely unacceptable to find excuses about imperfection like lack of time for fixing it. The only result I am satisfied with is the perfect job.
ANGIE SEGATTO DDS., ATTILA BÖRÖCZKY MDT., EMIL SEGATTO DDS. PhD. - MULTIPLE MAXILLARY DIASTEMA CLOSURE


The less invasive therapy for the volumetric and dimensional deficiencies of teeth is the additive-only procedure with prep-less or no-prep porcelain veneers. In the cases when the dimensional deficiencies result in different sized space distribution, there are several choices at the clinician’s disposal. Nowadays, according to the modern minimally invasive approach, we make an effort to damage the teeth as little as possible.
spot The two-year long follow-up confirms that neither esthetic nor periodontal deformations have appeared around the veneers. In case of adequate indication, the perfectly implemented no-pre segmented veneers being well-treated by the patient ensure a perfect final clinical and esthetic outcome in the long term.
LUIS CALICCHIO et.al. - ART AND TECHNOLOGY: DIFFERENT POSSIBILITIES FOR THE CONSTRUCTION OF A SMILE

The great challenge of cosmetic dentistry is the reproduction of the naturalness of a smile. The tooth structure to be created must be in harmony with the other existing teeth and the traits of the face and lips of the patient. For this, the human being seeks to mimic nature, having a model reference. The study of biomimetics revolutionized the way of making restorations for dentists and laboratory technicians.
spot Reproduction of a natural tooth is always a challenge for the dentist and the lab technician. The use of appropriate techniques and technology, combined with the talent of the ceramists allows us to create virtually invisible restorations. In the case presented we can see how the CAD/CAM can be a strong ally to the technician, facilitating the reproduction of the shape and texture of the surface of a tooth, ensuring maximum naturality.
LUZ ANGELA RAMÍREZ, TOLE ANDRADE, LUIS FERNANDO REY - BEYOND THE DENTAL CHAIR

Aesthetics has always been a fundamental part of human expression. Today, advertising in the media and social networks are persuading people about an ideal of beauty, where they can observe other people in beautiful places and with beautiful lives. Therefore, health and beauty are two concepts that have gotten importance in colombia and south america, motivating people to take decisions about aesthetic surgeries and dental procedures.
spot The popularity of dental designs in Colombia and South America has become an aesthetic trend. Each day the people seek help to look good, thanks to the influence of the media through aesthetic advertising or by their own conviction. Whatever the reason, contemporary dentistry can meet the expectations of patients by proposing treatments that are minimally invasive and aesthetically functional. The successful results have been achieved thanks to favourable evolution in the communication between dentist-technician and patient. Our biggest satisfaction will always be to receive a sincere smile full of gratitude from our patients and dentists. When we observe the role of emotions in the patient who experiences a real change in her life, we understand what is emotive dentistry.
DR. DIMITRIOS SPAGOPOULOS, MDT. NONDAS VLACHOPOULOS, DR. STRATIS PAPAZOGLOU - RESTORING CENTRALS WITH MINIMALLY INVASIVE PRINCIPLES

Due to the surgery the tissues in the area #12–22 became more reddish but they were clinically healthy. Apical to the free gingiva of the #11, 21, 22 scar tissue could be found. Discoloration of #21 was apparent when the patient smiled.
spot The prepared teeth were so conservatively prepared that they were mostly in enamel, therefore, they were etched for 30 seconds and a 4th generation bonding agent was applied. The intaglio surface of the veneers was etched with 9% hydrofluoric acid for 20 seconds and then orthophosphoric acid 36% was used to clean it.
MDT. PARK CHUL HAN, DR. DONGSUK KIM - A JOURNEY INTO THE UNKNOWN

My lateral teeth were microdont and had totally unbalanced appearance. I was disappointed about my edge-to-edge bite. As the saying goes, ‘You can’t shave your own head to be a Buddhist monk’. Therefore I asked my friend whether he can make laminates for me using non-invasive technology. I decided to have noninvasive laminates because I also work as a dental-technician and I know about the importance of aesthetics and function.
spot I wanted a journey into the unknown world with my friend. It was with REOX Art Oral Ceramic Powder. After the final stage of the treatment, I got more natural looks and a wonderful smile-line! And finally I got normal occlusion. I am a dental technician and my main field of interest is occlusion and aesthetics. After the final seating, I was satisfied with the result. I was very happy as a patient and friend with my new natural smile.
DR. RAFAEL LAPLANA, DR. ANABELL BOLOGNA - MINIMALLY INVASIVE ESTHETIC APPROACH IN FULL MOUTH REHABILITATION WITH CERAMIC RESTORATIONS, IN AGED DENTITION

The greatest clinical challenge when offering an aesthetic restorative treatment is to preserve as much of the remaining healthy tooth structure as possible while looking for simplicity and predictability in the restorative procedures, not only regarding function but also regarding longevity and durabilty of restorative materials, in order to achieve the aesthetic improvements from a functional approach. Nowadays, this is possible, due to two key elements: the adhesion, and the evolution of new generation restorative materials.
spot Final intraoral views show biological and functional integration in the full mouth rehabilitation. Smile and lower facial third show improvements in tooth proportions, while keeping a natural appearance regarding the characterization of aged teeth, which was highly requested by the patient. Pre- and post-treatment smiles are compared. The facial fullness is restored, and a better projection of the upper lip and a transversal support is achieved, which rejuvenates the lower facial third and the entire face.
PROF. LOUIS HARDAN - MOBILE DENTAL PHOTOGRAPHY (MDP): A NEW ERA IN DENTAL PHOTOGRAPHY

Nowadays, photography is becoming more powerful in dentistry and dentists are trying so hard to take good pictures for different purposes. For that reason a professional camera with all the accessories (ring flash, twin flash, macro-lens…) is needed, but not everyone can afford it or knows how to use it in the right way.
spot The procedure is so easy: Plug the Smile Lite MDP, open your mobile camera, zoom, focus, and take the picture, most of the time in Auto Mode. The results are very promising; by comparing pictures taken with professional cameras (DSLR) and Smile Lite MDP, the difference is getting smaller. With the evolution of mobile cameras, the future of MDP is becoming brighter.

INTERVIEW WITH MDT. OLIVER BRIX
GO YOUR OWN WAY AND NEVER TRY TO COPY ANYONE


We are completely aware that when we make teeth we are dealing with nature. And nature is so diverse. Even if you think you’ve done everything right, we are still anxious, we are still afraid. And this kind of fear persists right up till the moment when you take out the temporary. Sometimes we look at each other and then we place the crown and you can see the result in our eyes: tears or a smile.
spot One of the biggest problems is that we are still working separately and sometimes one side of a team has no idea what the other side is doing. We technicians can learn so many things about the intraoral scenario and dentists can learn so many things about realistic workflows and materials selection. And if you combine that: what a team! So that’s probably my vision as well.
CDT. STEFANO ESPOSITO
VENEERS - A NEW STRATEGY


The world needs beauty everywhere and it surrounds us. We are targeted by advertising, television and magazines that tell us what we should be like. This issue is emphasized even more in aesthetic dentistry. Porcelain veneers play this role in modern dentistry. Their market is increasingly growing, and they should be paid more and more attention to.
spot A careful observation of ceramics reveals that there is a greater translucency, a little opacity and controlled porosity. I have no scientific evidence that my method produces a significantly better result, but in my experience I have noticed better quality. The high quality of the performed work is also proved by the delivery.
DR. CLAUDIA VOLPATO, DR. LUIS GARBELOTTO, DR. MARCELO ROCHA, DT. CARLOS PRUX LANDMEIER - LAYERING CERAMIC ON ZIRCONIA ABUTMENT

Zirconia has been used for customized abutments manufacturing due to its good biological and mechanical properties. However, in order to obtain a proper esthetics, ceramic prostheses should be cemented over these abutments. The adhesive bonding is the most appropriate.
spot In this case, an implant-supported ceramic crown was made from a CAD/CAM customized zirconia abutment which received ceramic layering. This laboratory conduct allows the maintenance of a suitable emergence profile, the access to the screw hole, as well as an excellent esthetic result.
DDS. GIORGOS DIMITRAKOPOULOS
HEALING - RESTORING THE ANTERIOR AREA


A lot of times, during adolescence, our patients have accidents that cause severe traumas on the dental tissues. In this case, we will present a young man seeking for a more natural rehabilitation after treating his central incisors at a younger age.
spot The therapeutic scheme in those days involved two endodontic treatments of the #11 and #21 as well as two PFM jacket crowns. However, the restorations failed in an esthetic and biological meaning, causing discoloration of the teeth and creating periodontal problems in the soft tissues.
RDT. HIROKI GOTO
THE HYBRID RESTORATIVE DESIGN


In today’s world of comprehensive dentistry, there are numerous options for treatment plans and material choices. It is critical that the dentist and dental technician work together to choose the best combinations of options given the biological, mechanical, esthetic and biomechanics needs of patient.
spot I’ve recognized that blending of traditional concepts matched with some of the newer, for example CAD/CAM technologies is appropriate. A ceramist should have options to reproduce the color for each different material and restorative design.
FEDERICO PRESICCI -
FLEXIBLE AND VERSATILE: COMPUTER-AIDED DESIGN AND MANUFACTURING (CAD/CAM)


There is one thing that everyday objects and utensils have in common with products that have to meet stringent technical or medical requirements. If they are designed digitally, it is possible to produce multiple copies over and over again – even from different materials.
spot In the dental field, the fabrication of custom-dimensioned and stable restorations using a CAD/CAM milling unit has become an established procedure. It is important, however, to use the correct parameters for the material used, such as wall thickness, width of the cementation gap, connector diameter, sintering shrinkage, sintering support for distortion-free sintering — and more.
DR. MORVARID SEPHER KESHVARI -
THE PERFECT imPERFECTION


Every day we are faced with patients with skeletal disorders, where creating harmony and function must be done with orthognathic surgery, otherwise we put the patient in functional and aesthetic facial disharmony if he/she is just treated by orthodontics. The facial examination must always start by observing the patient sitting in front of you, looking him/her in the eye and at the same height.
spot Firstly, we have to detect if the patient has vertical disorders, then transverse disorders and finally, sagittal complications. The latter one must be observed with the patient on his/her side-face. In 80% of the cases, only with clinical examination can we reach the diagnosis of maxillomandibular asymmetries, which is the most complicated skeletal alteration, almost impossible to cover.
MDT. YUGO HATAI -
THE SMILE BIBLE


Smile Makeover seeks to meet patients’ aesthetic needs, as it is the patients who ultimately determine the success of any procedure. However, dental professionals can assist the process by educating patients and ensuring that all parties agree to each stage of treatment. Thus, it is essential that dental clinicians determine and document in detail any information provided by patients and adequately convey this information to the dental technicians.
spot Entitled ‘The Smile Bible’ this article serves as a communication tool between dental clinicians and dental technicians, dental clinicians and patients and dental technicians and patients. It outlines what materials should be used and when, what aesthetic issues should be discussed during consultations with patients, the importance of dental photography and what information is required by dental technicians/ceramists to process cases with confidence and minimize any possible errors that can arise during the try-in and insertion phases.
MDT. OLIVIER TRIC and MSC. SUSAN E. TRIC
STRATIFICATION - THE ART OF LAYERING


Stratification, the formation of layers, is found everywhere in nature: whether one observes geological wonders such as the rock formations where we see layered rock very clearly, or whether we view a slice of a tree trunk, the majestic rings which reveal a tree’s age as with each passing year a new one forms, we evidently encounter this common trend all over the natural world. Perhaps this is why one of the most exciting stages in dental technology is the layering of porcelain.
spot This is where we can give life to our porcelain restorations and mimic the surrounding natural dentition. Mastering layering requires us to develop a personal technique, understand the different materials and their properties, comprehend the fundamental theory of color, and finally have years of experience. Possessing all of these elements provides us with the conditions to approach the beauty of nature with dental ceramics. We must understand that there is no perfect formula that can be applied for every tooth and every case. Each case is unique and must be analyzed in depth prior to determining how to proceed and which customized layering strategy to apply.

INTERVIEW WITH DR. SIDNEY KINA
Dental Knowledge and Zen


„I am a very simple person with a very simple philosophy of life: Zen philosophy. It’s the way I think about everything. The idea is, to take advantage of every moment. It’s about living in the moment without distraction. For me, distraction is to come up with an idea which is different from what is real.”
spot I wish the readers a very fruitful professional life. In order to have one, you must have a professional philosophy which you can follow with all your heart because in that way you will be able to be relaxed in both your professional and personal life.
Feel free to pursue your ideas and especially your intuition. It will never let you down. No matter what other people say. Always follow your heart.
COMPLETE MAXILLARY AND MANDIBULAR REHABILITATION
MDT. BJORN BORTEN, DT. STEIN AANERUD


Missing teeth can cause anxiety in social situations as well as missed job opportunities and problems in basic everyday activities like talking and eating. Cases of patients with social anxiety can present a challenge for technicians and dentists, aware of the important role that an accurate dental service can play in improving the social situation of the affected patient.
spot “It was good to observe how much one can help both sociologically and socially in creating such a rehabilitation. The patient shaved off his beard, which he used to hide behind for some years.”
This case gave us proof that dentists’ and technicians’ own abilities in combination with the precision obtained by the new digital workflow makes it possible to provide an accurate and aesthetically suitable rehabilitation, with the full satisfaction of the patient.
FUNCTION – THE NEW DEFINITION OF OCCLUSION - DR. JAVIER VASQUEZ

“Function” is the new definition of the occlusion based on bio functional human dynamic analysis. Traditional occlusal concepts that most people practice and we learned in dental school are based on assumptions of how the mandibular dynamics works. Most of the concepts were based on cadaver studies, anatomical analysis, and manipulated pattern of movement since the cadavers could not recreate the function of the muscles during a physiologic functional activity.
spot Technology evolution is observed every day and we advance with the software and the new features that become available. Many of these features that we have now keep us in constant development, encouraging us to look for new innovative tools to facilitate a better workflow and to improve the communication between dentists and technicians, and to be able to take advantage of the new technological advances of this new 3D and CAD/CAM integration era.
INTRAORAL PHOTOGRAPHY
DT. LAZAR DAN, DR. JORDI P. MANAUTA


The main purpose of dental intraoral photography is to have medical information about the patient’s status. It is very powerful medical data that is non invasive and less expensive, for the patient and also for the dentist. I have stopped taking a lot of intraoral pictures that will be stored somewhere on my computer hoping that someday I will use them for some reason.
spot Do not forget that the intraoral pictures were used earlier for medical analysis. They are non-invasive, easy to take and less expensive. The artistic pictures are very nice for marketing reason, but have very low medical value.
CORRECTION OF VERTICAL AND HORIZONTAL OVERBITE
NELSON DÍAZ SIMONIN


The application of porcelain veneers is becoming more and more popular and very predictable treatments can be provided without forgetting to give back imperceptible aesthetics and beauty. In this case, we face a vertical and horizontal overbite of a patient with a previous orthodontic treatment and to achieve an overbite with excellent result, we use six superior and six inferior porcelain veneers.
spot The aesthetic needs of patients are becoming more demanding nowadays. It is our obligation to live up to those needs and exceed expectations of looking for a perfect smile, harmoniously integrated, functional and extremely beautiful soft tissues. When treatments use such a broad range of approaches, excellent results are easy to reach. Creating a smile like this always brings great satisfaction.We did not only work with the patient’s teeth, but we had a significant influence on her personality.
AESTHETIC REHABILITATION USING FELDSPATHIC VENEERS
MDT. NONDAS VLACHOPOULOS, DR. DIMITRIOS SPAGOPOULOS


Smile enhancement involves synergy between pink and white aesthetics. It is very important in complex cases to have control of each procedure, namely, restorative, surgical and laboratory, to achieve success in the whole rehabilitation. The team of clinicians and the technician have many ways of transforming the soft and the hard tissues predictably.
spot In this case, a 22-year-old female with an inclination of the midline and gummy smile wanted to improve it. Shifting the linear axes of the teeth and correcting the soft tissues is a delicate procedure that must be very precise.
GERBER METHOD – FULL DENTURE MADE WITH INDIVIDUAL VALUE
DT. RÁTONYI JÓZSEF, DR. PIRINT ÁGNES


Our patient is a middle-aged lady who has worn a removable partial denture for twenty years. After losing the remaining teeth as a side effect of radiation treatment for a malignant tumour, this denture was extended. Wearing this caused a feeling of discomfort; deterioration of the teeth made chewing impossible. Only the height of bite of the old denture was correct, and this was recorded.
spot Final shaping is minimal for a characterised denture, as any grinding would immediately change the projected layer pattern. You must proceed prudently at the anatomical wax-up stage and form the final dimensions of the denture. After sanding off the minimal burs, the surface can be made more exciting with a stippling drill and finally the prosthesis is polished, for which I used KMG paste, a small Robinson brush and a chamois leather disc.
DETAILED, ILLUSTRATED REVIEW OF THE LIVE PATIENT COURSE
DT. Sébastien Mosconi , DR. Marie Clément , DR. Cyril Gaillard, DR. Renaud Noharet


Our creation has to be integrated in the patient’s mouth effectively and as harmoniously as possible. This hand-made technique using platinum leaf seems to correspond to the aesthetic demands of the dentist’s eyes, as well as those of the patient. Within DSD France course set up by Doctors Clément, Noharet and Gaillard, a patient was treated by means of veneers which we made on platinum leaf.
spot The quality of communication between the trio of surgery – patient – laboratory is a pledge of an optimal result, in which DSD is a very useful tool.
In these three days of the DSD France course, a great deal of stress and emotion was experienced. As the patient had to be treated live in a limited time, there was no room for improvisation. The patient departed delighted with his new smile and the three days he had spent among dentists and technicians.

INTERVIEW WITH SHIGEO KATAOKA
‘If you follow your dream, great things will happen’


He set up his Osaka Dental Studio in 1969, and completed his training at the Yukioka Medical Technology School in 1972. He worked for the Apex Company in the USA as a teacher from 1980 to 1983, and founded the Osaka Ceramic Training Centre in 1984. Four years later, he established his private laboratory Kataoka Ceramic Ltd and in 1993, the Osseo Integration Implant Laboratory both in Osaka, Japan.
spot In the end, I always feel there is still something lacking. The thought that I made something that hasn’t the right shape and form motivates me to take the next step and to try to achieve true perfection the next time. There is no progress if you are satisfied with your work. You always need to ask yourself what’s missing, why you did not achieve perfection. If you have a clear picture in your mind of what the end result should look like, a restoration will take relatively little time.
DIGITAL DENTISTRY - BEYOND ITS LIMITATION
CHANG HWAN KIM


We performed a lot of dental prosthetic treatments using analog technology. The CAD/CAM system has been adopted for over 20 years, but now we are just starting the new digital phase. For years, we have just been improving the materials and machines, and not the technique for utilizing digital methods.
spot Now we are facing a new digital world because we can create dental prosthetics without the model, using “modeless” technology and oral scanning. However, I believe that we can get the best results by using the knowledge of the “old” analog technology to help improve the new digital technology. This article will introduce some of my cases to address the digital dental prosthetics and technology.
ART AND SCIENCE TECHNOLOGY
DR. JOSÉ VILLALOBOS TINOCO


The growing amount of available dental materials and the changing concept of restoration odontology contribute to the implementation of more predictable treatments and to restoration of function and aesthetics. Adhesive systems and CAD-CAM technology also offer amazing opportunities for the odontologist.
spot Since the introduction of CAD-CAM technology, the speed and precision with which dentists can place high-quality, aesthetic restorations in many situations have significantly increased. In the future, the precision of computeraided technology and human creativity will have to be combined and in the right and experienced hands, CAD/CAM technology will offer tremendous benefits to both patient and doctor.
PALATALLY SCREWED FULL ARCH RESTORATION ON IMPLANTS
DR. MARCO MAIOLINO


Nowadays implant therapy is a broadly accepted form of treatment and the high percentage of success of osseointegration is no more a debate. Unfortunately, there are still a lot of studies about prosthetic complications. The conventional solutions in dental implant prosthetics are usually divided in 2 big families: the cemented and the screwed prostheses. Both present advantages and disadvantages.
spot The main drawback of the cemented prosthesis is its difficult retrievability. After the cementation of the work, in case of complications, the removal of the work is not so easy and patient friendly. On the other hand, the main advantage of the screwed prosthesis is its retrievability. Nevertheless, we have to face the problems of occlusal holes and the problems that the angulation of the implant is prone to a hole in the buccal part of the crowns, often in the esthetic area.
MICRO AESTHETIC DENTISTRY - THE WHITE AND THE NATURAL
NASSER SHADEMAN


While it’s a fact that machines make manual processes much more easily and faster, this does not undermine the ultimate strength and superiority of the most sophisticated machine, the human mind and his fine craftsmanship. It is perennial truth that the human mind is superior to machines and that machines are only there to serve a well-defined purpose.
spot In my view as a tooth artist, ceramic, composite or wax are equally capable of creating the illusion of natural tooth and its surrounding gingiva. That means a tooth artist is not limited by differences in consistency or formability of certain materials, because learning tooth artistry will introduce us to the power of freedom and absolute control working with different kinds of restorative materials.
REPAIR OF PRIODONTALLY DAMAGED LARGE INCISORS
DT. ATTILA KUN


The aim of this work was to repair the periodontally damaged, large incisors. In order to stabilize the crowns, we decided to connect the two incisors in the front. During the stage of the Wax-Up, we discovered that one of the small incisors is narrower. In order to enhance the symmetry of the large incisors and keep their natural width, we decided to create a non-prep veneer on the small incisor.
spot As the stumps did not have any discoloration – although they were labially elongated – we needed a zirconium frame, which can transfer the natural color of the stumps. Furthermore, it can tolerate a bit of material thickness due to the lack of space around. We created a partially reduced frame from Katana UTML. In this way, we had the chance to use a thin layer of ceramics (Noritake CZR).
FULL-ARCH IMPLANT REHABILITATION USING ZIRCONIA FRAMEWORK
DT. CRISTIANO SOARES, DR. GUILHERME DUARTE, DR. LEONARDO BUSO


When it comes to oral rehabilitation, choosing the best material is always an issue to be concerned with. High aesthetics and minimally invasive approach are essential goals in modern dentistry, although the lack of material know-how and high cost may interfere in the process. It’s up to the dentist and the dental technician to find out the best way in order to fulfill patients’ expectations.
spot The decision-making process on high aesthetic demand oral rehabilitation should be based not only on common-sense but also evidence-based dentistry. The treatment plan was essential for the aesthetic-functional outcome as well as for longevity and predictability success. Technology associated with handcrafting technique has shown as a modern tendency whereas the precision of CAD/CAM restorations may be improved by the human touch.
DIGITAL SMILE DESIGN – INTERDISCIPLINARY APPROACH
DR. ERNESTO ENRIQUE DIAZ GUZMÁN


Limitations in treatment planning are unpredictable due to poor communication between operator – patient, interdisciplinary team, lab technician and clinical factors overlooked by the lack of information.
spot Tools such as photographs, videos and computer are essential for communication with the patient to create expectations through prototypes that can result in a temporary restoration that will help us see the functional, biological, mechanical and aesthetic performance of the final restoration.
TOTALLY INVASIVE!
DR. RENAUD NOHARET, DT. SÉBASTIEN MOSCONI


The 42-year-old patient appears for consultation to a general periodontal disease and some recurrent abscess around his teeth. The majority of his teeth are mobile. During the clinical examination, we notice that he suffers from generalized chronic periodontitis one. He has already had some periodontal treatments but without success. He complains about the loss of teeth and a disharmonic smile.
spot Our goal of treatment is to treat this patient for function and esthetics. As only some teeth are valid, we decide (based on a discussion with the patient) to extract all teeth and to put implants in 2 arches. The treatment takes one sitting: immediate placement, immediate function on full arch. This treatment avoids bone graft and long time of treatment. In order to optimize the duration of the surgery and the goals of the treatment, we decide to use guided surgery for maxilla and mandible.
