Conferences

  • Thursday 3 October am
    • 10h-12h – Challenge Ose ta conf’ !
    • 12h-13h – Jacky and Franck PENNARD – The way of aesthetics. Understanding failures and successes in all ceramics
      • Zirconia and lithium di-silicates can meet the aesthetic expectations of patients and practitioners. Manufacturers are constantly changing the characteristics of these materials. Therefore, a better knowledge of their properties makes it possible to establish adapted protocols, guaranteeing the durability of the prostheses. What translucency and strength will be adapted to make a full zirconia or implant bridge? What are our choices to optimize manufacturing processes and colour control? What are the most frequent causes of failure? The carving of the preparations, the design of the infrastructures, the chipping, the work on colour, the cooking are all elements that we will study in response to these problems mentioned in different studies. It is through the mastery of materials and their implementation that we can hope to reach our aesthetic ambitions.

    • 15h-16h – Michel BASTIDE and Rodolph MARTIN (HENRY SCHEIN) – Primescan the daily Connection of the dental clinic to the Laboratory
      • In the era of digital flow, communication between the dental office and the laboratory, through an intraoral scanner, has become a reality. Michel Bastide and Rodolph Martin will make you discover their everyday life, from simple restoration to complex implant cases. How thanks to the common digital flow they communicate in a safe and fast way to each step of the prosthetic realization, and this winning partnership which brings them precision, and durability.
    • 14h-17h45 – Pascale CORNE (COLLEGE NATIONAL OCCLUSODONTOLOGIE) – Occlusion management for fixed prosthesis by direct CAD/CAM
      • At a time when everything is going digital and as digital impression technology via intra-oral camera is increasingly used by dental firms, design management for the general practitioner remains a particularly delicate phase of direct CAD/CAM. Design aid tools are there to help us provide the very best management of the future dental anatomy, in particular at the level of the occlusal surface. This lecture aims to present and show the use of CAD/CAM tools and the advantages of optical impression in the context of unit restorations and even comprehensive prosthetic rehabilitation.
    • 14h-17h45 – Olivier ROBIN (COLLEGE NATIONAL OCCLUSODONTOLOGIE) – BruXense: a connected device for recording bruxism
      • Bruxism is a frequent parafunction that results in an often unconscious behaviour of clenching and/or grinding of the teeth, causing sometimes severe aesthetic and functional damage (wear, dental or prosthetic fracture, myalgia, joint dysfunction, etc.).
        Currently, there is no reliable device for detecting bruxism that can be used in outpatient settings. The clinical signs usually associated with the diagnosis of bruxism (hypertrophy of the masseters, dental wear) are not sufficient and all too often lead to an underestimation of this phenomenon.
        The aim of this lecture is to present a device, designed and developed by a team from INSA Lyon, to record bruxism during the night. This device (BruXense), consisting of an instrumented occlusal splint and a refill base, allows to characterize the episodes of tooth clenching and grinding in terms of frequency, duration and intensity. This presentation will be illustrated by the description of the device and examples of recordings carried out on different subjects in the context of a clinical study.
    • 14h-17h45 – Guillaume BONNET (COLLEGE NATIONAL OCCLUSODONTOLOGIE) – When the complete removable prosthesis meets the digital world: How digital tools are becoming an answer to the problems of occlusion management
      • The complete removable prosthesis is one of the oldest prosthetic disciplines. Yet, more recently, when preparing oral-dental prevention campaigns, the feeling has been that this oral rehabilitation method was on the decline. The increase in life expectancy, however, is leading, on the one hand, to an increasing number of prosthetic renewals and, on the other hand, to an increasing number of new patients to be rehabilitated, and these tend to show that this discipline is still relevant in 2019. At the same time, alternatives to this first-line rehabilitation (implant therapy) remain relatively expensive and are not feasible in certain medical or surgical situations.
        Digital tools, already highly developed in the industrial world, made their debut in the field of dentistry in the early 1980s. These tools which form a real digital chain (acquisition, modelling, production) are today a daily alternative in fixed prosthetic rehabilitation.
        The first research work on complete, digital, removable prostheses dates back to the mid-1990s. This new technical evolution of Computer Aided Design and Manufacturing (CAD/CAM) has grown exponentially since then, alongside published research. Based on the PUBMED database, only one article was referenced in 1998, 15 articles in 2008 and 78 articles in 2018. In 2019, several complete systems are available on the international market. In 2015, the Odontology Department of the Clermont-Ferrand University Hospital acquired the complete Ivoclar Digital Denture system.
        This presentation aims to explain the interest and limits of these new digital tools for what is a highly specialised discipline, namely the complete removable prosthesis, and in particular the management and implementation of the most favourable occlusion.
    • 14h-17h45 – Maxime JAISSON (COLLEGE NATIONAL OCCLUSODONTOLOGIE) – 4D Dentistry. New digital dentistry driven by 3d modelling, jaw motion, and dynamic occlusion
      • The concept of 4D dentistry introduces a new way of entering into the reality of our patient by using his true mandibular kinematics as well as his dynamic occlusion, which is then combined with 3D modeling. The principle is based on the idea that static and dynamic parameters should be taken into account in order to allow for the development of tailor-made rehabilitation and a complete functional diagnosis. We will see how this new dimension can simplify our procedures, increase our knowledge and encourage exchanges in the tryptic patient practitioner-prosthetist.
    • 14h-17h45 – Thomas FORTIN (COLLEGE NATIONAL OCCLUSODONTOLOGIE) –
      • Work in progress
  • Friday 4 October am
    • 9h-18h – Christian COACHMAN – Digital Smile Design Day
    • 10h-11h – Christophe SIREIX (CIRCLE) – Digitalization of dental practice by Circle and the Biotech Dental Group
      • Work in progress
    • 11h-12h – Jean-Pierre LE VOT (ZIRKONZAHN) – New challenge for the dental technician
      • During his presentation, the author will focus on new software possibilities. It is now possible for dental technicians to respond to requests from practitioners to design and manufacture surgical guides in the laboratory.
        In perfect consultation with its clients, the laboratory technician can now offer a pre-implant study, corresponding precisely to a available bone volume while integrating perfectly the future prosthetic project.
        These case studies, validated by the practitioner will then allow the manufacture of surgical guides, either by additive technique, 3D printing, or by machining In perfect consultation with its dentist or stomatologist clients,
        the laboratory technician can now offer a pre-implant study, integrating all STL files from the laboratory, as well as Dicom files from the dental office. All these correlated data will make it possible to use as much as possible the available bone volume, while respecting the future prosthetic project.
    • 12h-13h – Germano ROSSI and François LELIEVRE (DENTAURUM) – 10 keys for success in full zirconia restorations
      • Zirconia has improved more in the last 5 years than in the previous 15 years. The opaque material of the beginnings has become a formidable challenger to all conventional materials used for the prosthetic restorations. .
        What can we expect from this material today?
        What are the limits from an aesthetics point of view ?
        Which advantages can you take of its physicochemical properties?
        What are the latest finishing techniques?
        Improve in safety and cost : Myth or reality?
        Germano Rossi ceramic dental technician and François Lelièvre engineer in material sciences will address these questions and many others during a presentation with scientific data and clinical cases.

  • Friday 4 October pm
    • 14h-15h – Alain ARDIC (ANTHOGYR) – An innovative answer to single aesthetic restorations challenge
      • When making a screw-retained prosthesis in the dental laboratory, the positioning of the screw channel in the center of the palatal face, or outside the occlusal contact points is a common problem.
        The latest Anthogyr prosthetic innovation, AxIN, is a customized screw-retained single tooth, with angulated access from 0 ° to 25 ° and a narrow screw channel, which reinforces the free edge of the prosthesis and results in a better aesthetic result.
        The objective of this conference is to present the specificities of this unique solution, which increases the field of indications of the screwed prosthesis and is part of the current trend of reduction of the risks related to the sealing.
    • 15h-16h – Eric BERGER (VITA ZAHNFABRIK) – The digital artisan : Integration of aesthetic materials in the daily practice of the laboratory
      • The world of CAD / CAM is constantly growing, offering us every day new spaces of applications. But in this new universe, what is the best material for the best aesthetics? From simulation of the smile on real achievements, we will develop our reflection for the choice of the good material. This necessary expertise for each case is changing our status as a craftsman to true digital artisans.
    • 16h-17h – Edouard LANOISELEE and Yannick GOURRIER (3 SHAPE) – The patient at the heart of the digital dentistry
        • The contribution of digital technology in the practice of contemporary dentistry has considerably changed.
          This conference will focus on the diversity and new applications of dental care offered by the digital solutions.
          From diagnosis to 3D imaging, from digital impression to prosthesis production, from planning to the prosthetic project and the guided surgery, the digital environment intervenes at each stage and brings a valuable help, allowing to propose to the patient aesthetic, functional and preservative therapeutic solutions.
  • Saturday 5 October am
    • 11h-12h – Laurent MANEVAL – Economic revolution of the digital chain in the dental field
      • While dental labs have been working for years with CAD/CAM, dentists on the other hand, were to this day unwilling to use intra-oral cameras. The obligations of the future National Agreement as well as the recent special offers, have eliminated the last blockages. Camera sales are initiating a spectacular and irreversible increase. The digital chain is therefore complete and its economic impact on the activity of laboratories and dental practices will be considerable.
        Through several practical and well-argued examples, we will explain in detail the important change to come that will upset the dentistry economy, along with the foreseeable consequences which will need to be anticipated.
