“oral design



Keywords:  oral design, movie 

In the transition era of metal ceramics to all ceramics, esthetic dentistry has evolved.  This evolution is not only due to materials but also the development of digital technology, including cameras.  Unlike film photography, which is technical sensitive, digital photography enables users to understand the method of photography more easily.  In addition, we should keep in mind that there is a possibility of data manipulation done.  In other words, we never know what the reality is.  Digital photography has changed the way we handle photography completely.  


While I have doubted what the reality is, I encountered videography.  I felt that it is the best way to convey my own daily work, not only restorations but also the patient’s personality and expression.  Documentation of the restorations can be done multi-directionally.  This may be the best way so far to present the restorative treatment, which improves the patient’s oral condition and personality.


In this lecture, I will present a movie for you to see and feel my daily practice through explaining how I design the patient’s oral condition.

DENTSCAPE: Dental Photography for Dentist - Laboratory Communication



Keywords: Basic knowledge of photography, facial view, analysis of midline and incisal plane, analysis of shade

The advancement of digital cameras made photography more popular than ever. However, many dentists and dental technicians are still struggling to photograph images which precisely convey esthetic elements for fabrication of restorations.


In this presentation, Naoki Aiba, CDT will address the following three points to explain the fundamental of dental photography as a communication tool, photographing methods, and applications.


1. Basic knowledge of photography that dentists and dental 

    technicians should know

2. Method of photographing facial view, and analysis of midline

    and incisal plane

3. Method of photographing shade photos, and analysis of



Numerous clinical case examples will be discussed to illustrate how the photographic information was materialized into ceramic restorations.

Keywords: Emergence Profile, S Shape Profile, Fluorescence, Two types of Values  

I got an opportunity to study under Mr. Willi Geller in Zurich, Switzerland.  Every time a patient comes to the lab, Mr. Geller showed me how the restorations looked in the mouth.  It was a very valuable experience for me.  What I was impressed the most was that the restorations made by Mr. Geller harmonized in the mouth – I could not distinguish the restorations from natural dentition – not only the restoration itself but also the harmony of the cervical aspect of the gingiva was amazing.  I felt that Japanese dental technicians at that time were focusing on fabricating the restorations that looked realistic on the models, but not in patients’ mouths, and so were the cases published in dental journals.  I was convinced that something was wrong in clinical practices in Japan.  It was in February of 25 years ago when I was 29 years old.


It has been more than 20 years since I have been working in a clinical setting.  During that time, my focus has been on harmony between restorations and gingiva, utilizing the concept of “S Shape Profile” advocated by Dr. Katsunori Nameta, in conjunction with working on emergence profile.  In clinical cases, in order to achieve a natural appearance, it is also important to match the shade of the cervical region, which interfaces free gingiva, while blending with surrounding dentition.  An appropriate amount of translucency, chroma, and fluorescence are essential to make a cervical shade of the restoration blend to the tissue.  The fluorescence of the crown part of the restorations has been often discussed in Japan, but what is most important is that fluorescence delivers the light to surrounding gingiva: thus; tissue appears healthy.  Dental professionals in Japan often overlooked this phenomenon.  In addition, in natural dentition with low chroma, the shade is not always just white; there is a tendency that other factors influencing the value to be high, which does not mean low chroma equals high value.  Natural dentition has intrinsic high value, which presents vitality unlike shade tabs, but at the same time, natural dentition has translucency.  It is challenging to replicate this type of characteristics, particularly in the shade matching of the cervical region. 


In this lecture, I will discuss the harmony by shape and that by shade, and procedure.

“Pursuit of Simplicity”



Keywords: Reducing remakes, Reducing production time, Producing high-quality restorations

It has been 26 years since I became a dental technician.  Time flies - we are at the mercy of time, and dental laboratory industry is no exception.  As the material evolves, "techniques," "precision," and " work philosophy" have greatly changed for better or worse.  Mr. Willi Geller’s presence and his philosophy have been constantly influencing me through the time.  For about three years, I was fortunate enough to study under Mr. Geller.  That experience is the motivation (motivation, desire, maintaining the quality) to my work now, and it is my continued passion.


Creation ceramic system developed by Mr. Geller has recognized as a porcelain for multicolor build-up, and it has misunderstood as a "difficult ceramic system," which required surpassed skills to handle.  Unfortunately, this is the reputation of Creation in Japanese dental industry.


Any dental technician aims the followings: 


(1) Technique for less chance of remakes

(2) Reducing production time

(3) Produce better quality restorations


To realize the above, it is understood to use user-friendly ceramic systems, which do not require complicated handlings.  It is less known that Creation porcelain can be handled simple method to achieve good result while achieving the above-mentioned aims.  


In this lecture, I will enlighten a new side of Creation porcelain – the original side - by illustrating the clinical cases utilizing Creation porcelain, focusing on the three points above.

“A Biological Approach to

Restorative Design” 




Keyword: S shape profile 

A research paper by Dr. Yoshinori Nameta, titled

Considerations on Free Gingiva in the Aesthetic Prosthesis: A Clinical Viewpoint on Epithelial Attachment” was published in 1995.  In 1991, Mr. Geller came to Japan to give a lecture.  I was a student at the Osaka Ceramic Training Center then.  I still remember clearly that I was impressed with his metal ceramic restorations that looked ordinary on the model looked so natural once they were seated in the mouth.


However, about the same time, some Japanese dentists, including Dr. Nameta, were also seeking gingiva-conscious prosthetic treatments.  Since then, I have been following the footsteps of Mr. Geller, who developed the Creation porcelain, and the team of Dr. Nameta and Mr. Odanaka by studying their prosthetic concept. As a result, it became clear that dental prosthetics fabricated with biological approach contribute not only esthetic but also longevity.


In this lecture, the advantage of S shape profile concept in dental prosthesis on natural abutment, and it’s applications on implant prosthesis will be discussed.

”My porcelain build up technique using CREATION porcelain. ”




Keywords: Opacity control,Opal control 

If the value control of the anterior restorations can not be approached in the patient's mouth. It will be forced to reproduce with high probability.  I still feel that it is a challenging task for dental technicians.


I would like to introduce my porcelain build up based on the value of transmitted light for the difference in transparency of individual porcelain powder with creation porcelain. In this lecture, I will explain two themes and the clinical case.


1.Consideration of the opacity level of each company's Dentin

   using a transmitted light measuring instrument.

2. How to control the opal effect strongness and weakness.

“Creating Emergence Profile & Color ”



Keywords: Emergence Profile, Natural Scalloped Form  

Any dental technician has experienced working with the cases that force him or her to create crown forms, which is far from that of the natural dentition, when the position of abutments and shape of margins contradict with ideal crown morphology.  This is because the fit of the margin is absolute and it cannot be ignored.


However, if a margin is set subgingivally, it enables for a technician to design the sub-gingival aspect of a crown, which is the concept of emergence profile.  If dental technicians can design an emergence profile, not only the contour of the crowns but also the gingival contour can be designed by the dental technician in some extent, and the dental technician would be able to contribute more on aesthetic outcome and prognosis.


In my lecture, I will explain how to achieve natural scalloped form by controlling the emergence profile with malaligned cases.  In addition, it is important to manage the value of dentin structure in shade matching: therefore; I will address how to achieve shade while considering the factors of value.

“Doing the Best for Smiles”




Keyword: Communication with patients

For 25 years since I became a dental technician, I strived to improve my skills desiring “I want to make a full mouth reconstruction case like what Mr. Geller makes.”


Two years ago, I encountered a patient who changed the way I think.  By that time, I was able to make the restorations with decent shade and shape.  When fabricating the restorations, it is normal for us to consider shade, morphology, tissue contour, tooth arrangement, smileline, and etc.  However, this patient changed me to think “what he or she want” from their point of view rather than our point of view.   I felt it is very important to understand what they want, and respect it, and support it to make modifications on the restorations.  As a result, the patient finally can smile – dentists and dental technicians should feel it as a pleasure - this is the success of the treatment.  


Therefore, I would like to share with next generation technicians the pleasure for fulfilling patient’s desires through communicating effectively.
