Selection among

A selection made for you among my 356 publications

Note: Please See page “research and publications” for more information’s (include all my 356 personnel’s publications from 1973 to 2021

To allow you to inform yourself quickly, this page presents a personal selection of 24 references (in black) that seem interesting and representative of my work for 50 years and more particularly 12 (in red) which deserve more attention in my eyes for anyone interested in the birth of digital dentistry, artificial intelligence and, of course, optical impression and dental CadCam.

These selected publications deserve a minimum of explanations, which you will find more detailed in the following pages.

First of all, and through my thesis (first chosen text) you will see that it was described in 1973 the totality of digital dentistry and artificial intelligence in dentistry. You will also see, in the various chapters, that if the CadCam was detailed, it was only detailed for the example, because my work focused on the contribution of digitization in the whole of our daily activity (see in particular chapter 9).  Finally, we may be surprised to see described techniques such as internet and clouds that did not exist in the early 1970s (??).

The following 11 references were selected with the aim of detailing and validating the master application at the time: the CadCam. For this reason, the components and software you use today are described for the first time as early as 1981. In particular, it includes the implementation of IOS with a CCD, image processing cards or surface modelling transmitting their information to numerically controlled machine tools (Ref # 14). Everything will be presented publicly and live in 1983 in Paris (video and ref #45). These publications or videos also show the first models of prostheses, including inlays, in STL by Bézier tiles in 1982 (ref # 14 and 20). Unlike other rather primary systems, they were already built with environment and static and dynamic occlusion. In the same year, you will also find a description of all the applications (fixe and removel prostheses, post, circular preforms, cone beam or thermal measurements) (ref # 30,31-35). It is in a 1985 article, No. 50 of the “cahiers de prothèses”, that everything will be detailed for dentists with in addition the introduction of the first workflow (ref. # 62-63). I would also like to draw your attention to the two technical documentations of specifications of 1984 (ref # 54) and 1987 (ref. #100) because they show that all the CadCam of today was already described there. (see 1990 Strasbourg video).

Then many will discover that the first real dental CadCam system on the market was the Hennson system (ref # 62-63). This French system was also the first to be presented in public and in congress (video 1985). It was not intended only for laboratories, as we read too often, but also for dental offices or in a mixed practice/laboratory situation (ref # 123).

It was not until November 1985, when I sealed in my mouth and in public the first real crown made by CadCam, adapted to its environment and respecting the occlusion as any prosthesis must, that I considered myself the inventor of this technology that I had imagined and described 15 years earlier in my thesis. Before this date we read in the professional press only more or less fanciful working hypotheses.

You will also discover that this French Dental CadCam System «Hennson» device was not just a prototype but that it worked regularly in cabinets or laboratories (more than 60 were sold) including at the University of USC (USA) and that, if the manipulation was not always simple, His results were satisfactory to those who knew him (ref # 171).

Beyond and in the other 24 references, you will also discover other of my often unknown inventions, the CadCam taking up all the space, such as the RVG in 1984 (ref. # 50), heterogeneous 3D structured composites (ref. # 78) fiber studs (ref. #145), the digital articulator (ref. #119), correlation systems used today in implantology (ref. 121 and 156-159), rapid polymerization (ref. #179), PLY (ref. 198), active bleaching (ref. #223), the optical imprint holder (ref. #288) described in my 1973 thesis, or other augmented reality (ref. #331 and 340).
