Le workshop vise à décrire le traitement des récessions au niveau des dents et des implants par la technique de tunnelisation. La technique de prélèvement ainsi que ses implications sur la bioactivité du greffon seront également abordées. Une brève séance pratique consacrée au prélèvement de greffons conclura cette session de conseils et d'astuces.

Il existe plusieurs protocoles d'augmentation des tissus durs et mous qui ont fait leurs preuves. Néanmoins, pour éviter les complications et optimiser les résultats, des protocoles stricts et rigoureux doivent être suivis. Les conditions préalables pour maximiser le taux de réussite et éviter les complications sont la sélection de la technique, la combinaison de biomatériaux (membrane/greffe osseuse), la conception du lambeau (incisions, mobilisation, fermeture de la plaie sans tension) et la stabilisation du défaut/de la greffe. Dans le cas de patients fragilisés, les géométries de défaut étendues et les protocoles chirurgicaux plus agressifs n'augmentent pas seulement le taux de complications, mais le résultat clinique devient également moins prévisible. Pour surmonter ces limites, la "biofonctionnalisation" des matériaux de greffe osseuse et des membranes barrières par des facteurs de croissance, des centrifugeuses sanguines ou de l'acide hyaluronique est devenue de plus en plus populaire. Ces additifs "bioactifs" ont le potentiel d'améliorer la cicatrisation des plaies et d'avoir un impact plus ou moins positif sur la qualité et la quantité de l'os sans qu'il soit nécessaire de modifier le protocole de greffe individuel ou la combinaison de matériaux. Au cours de cet atelier, une vue d'ensemble des preuves cliniques et scientifiques actuelles de la biofonctionnalisation est présentée et la pertinence et l'applicabilité dans la pratique clinique quotidienne sont illustrées par de nombreux cas cliniques....

La réhabilitation complète de la mâchoire peut être 100 % numérique grâce à R2Gate. Cette méthode vous permet de concevoir votre chirurgie implantaire avec la conception DSD et d'utiliser des guides chirurgicaux précis. La réhabilitation passive en zircone est réalisée directement sur le pilier, selon un protocole fiable et reproductible. Elle enseigne également comment concevoir et façonner la ligne dentaire avec une mise en charge immédiate du patient, ce qui rend les traitements fp1, fp2 et fp3 prévisibles sans avoir besoin de tibase, en passant directement à la zircone. Pour mettre en œuvre cette technique dans la pratique, il suffit d'une caméra numérique, d'un scanner intraoral et d'un CBCT.

Bone management is essential for implant long term success. There are lots of bone graft procedures to correct thin alveolar ridges (GBR, autogenous bone plates, tenting,…). Theses procedures can be performed before or during the implant placement. We will clarify indications of each surgical technique with several cases and decisional tree based on clinical and CT scan analysis. We will insist on the crucial role of the implant design for stability and mostly for bone preservation.

Over the past three decades, oral implantology has proven to be a reliable and predictable technique for the rehabilitation of edentulous spaces. Attainment of this goal, however, is predicated on the ability of the implant to achieve osseointegration with its bony environment. This process passes through a primary stage characterized by mechanical stabilization of the implant, and a secondary stage of biological anchorage, the actual osseointegration process. Different parameters such as bone density, implant macro and micro geometry and surgical techniques play a major role in achieving optimal implant primary and secondary stability. Understanding these parameters will allow us to predictably plan our future loading protocol (immediate, early or delayed). During this presentation, scientific and clinical rationale will be presented in order to give the clinician an evidence-based approach, for early and immediate loading protocol, in everyday clinical situations, by using implants with versatile thread geometry adapted to different bone densities.

New effective & predictable implant solutions in severe atrophic anterior ridge (Feat. See the Unseen)Since the initial adoption of the Branemark implant system nearly 50 years ago, there have been significant performance and technological advances in all aspects of dental implants, leading to osseointegration within a short time period and even immediate same-day prosthetics in many cases.However, placing and maintaining implants in a severely atrophic ridge in the anterior region remains a challenge when using conventional methods. Thus, a 6-unit bridge is commonly created using the relatively accessible posterior region instead of placing implants in a low and thin atrophic anterior ridge. Even when implant placement is feasible in the anterior region, esthetic considerations often require concurrent surgical procedures, such as GBR or bone augmentation, to recover the bone volume, thereby increasing the financial and psychological pressures on patients and involving longer recovery periods when compared to conventional implant treatments. Moverover, given the elderly profile of most patients seeking implant treatment, the perceived burden on patients is significantly higher, obtaining consent becomes more challenging, and there is an increased clinical concern regarding the maintenance and post-implantation issues.Therefore, using my 40 years of experience as an implant clinician, this lecture presents new effective solutions to facilitate implant placement in a severely atrophic anterior ridge, leading to an improved dental condition and higher patient satisfaction. Learning objectives - Understand the biologic concepts for hard and soft tissue regeneration and maintenance. - Understand long-term complications with immediate implant placement in anterior atrophic ridge. - Develop an understanding alveolar bone change and resorption before immediate implant placement

Guided Bone Regeneration (GBR) is a complicated process that involves the formation of new bone to substitute those that have been damaged or lost, due to various factors (diseases, trauma etc…). In recent years, many advances have been made in the field of GBR, offering new perspectives for bone regeneration. Among these progresses, the use of tissue regeneration membranes is a promising approach. The iGen membrane, developed and manufactured by MegaGen, is an innovative biomaterial that it’s been simplified protocols of bone regeneration. This membrane is made in Titanium and has the main advantage to be screw directly to the dental implant, without any additional screw or pins, thus making easier GBR procedures.

The concept of immediate functional loading is increasingly documented and fully validated in implant treatment plans, as it offers a number of advantages, in particular enabling patients' aesthetic and functional needs to be restored as quickly as possible.The use of information technology in implantology represents a major technological advance.Digital wax-up, implant planning, guided surgery and Cad Cam prosthetics are just some of the fields in which this technology can be applied.Working step by step throughout the implant treatment, the R2gate digital workflow makes it possible to offer immediate functional implant-prosthetic loading solutions, while optimising results in terms of predictability, precision, adaptation, safety and stability.This presentation describes and defines each of the elements of this digital workflow, and demonstrates the benefits of anticipating implant treatment by using Implantology 3.0 during the execution of all the elements in the implant chain, from the prosthetic project and the surgical phase through to prosthetic completion, for a better long-term result.

Dental implants play a crucial role in providing support, stability and retention for superstructures to achieve optimal esthetic and functional outcomes in dental rehabilitation. With the rapid advancement of implant technology, clinicians are challenged to stay abreast of the latest developments. Despite the established longevity of implants, there continues to be a strong interest in improving implant restorative treatment and outcomes. Recent innovations include novel implant macro designs tailored for optimal stability in various bone qualities and the integration of computer-aided design and manufacturing (CAD/CAM) for the fabrication of implant abutments and frameworks in various materials. Intraoral scanning and optical digitization of master casts further expand prosthetic options, facilitating the creation of customized abutments and restorations with enhanced predictability in alignment to the desired morphology. This presentation will emphasize the coordination between the restorative team and the laboratory, while critically evaluating the rationale for adopting digital workflows in implant dentistry. Emphasizing the intrinsic relationship between functional implant design and esthetic treatment approaches, the presentation delves into emerging techniques and their material nuances, offering insights into optimizing treatment outcomes.

As digital tools continue to advance, their integration into routine dental practice promises not only to improve the quality of care but also to revolutionize the patient experience by offering faster, safer, and more effective treatments. guided implant Surgery has led to the reduction of potential complications, and the enhancement of overall treatment predictability. R2GATE's Technology allows for precise surgical planning and the fabrication of surgical guides, ensuring optimal implant placement. The presentation will discuss key features of R2GATE software, including its ability to predict prosthetic outcomes, improve accuracy and its role in minimizing surgical time and improving patient comfort. This presentation delves into the innovative applications of R2GATE software in digital planning and guided dental surgery, illustrating how these advanced tools facilitate more predictable and successful treatments. Attendees will leave with a thorough understanding of how R2GATE software stands at the forefront of digital dental technology, offering tangible benefits to both practitioners and patients through innovative digital planning and guided surgical solutions.

Immediate implant placement was initially described by Schulte and Heimke, as an alternative to Branemark protocol back in 1978. Four decades passed by, thousands of case reports have been collected, prospective and retrospective studies delivered and backed upped with meta-analysis. Still, a majority of dentists consider the Immediate protocol as a risky concept, with unpredictable outcomes and a higher failure rate, compared to conventional delayed implant placement. In general immediate implant placement is considered as an option only in the aesthetic zone. However following publications analysing patient satisfaction, the conclusions show that the vast majority of negative patient feedback about dental implants is related with constant food impaction, following lost inter-proximal papilla and nature-inspired gingival contours. So what is missing in common dental practice to stop managing growing patient needs for a more satisfactory outcome of their treatment? No predictable protocols can be performed without the correct tools. So we present “ZBLC IN THE BOX”?
