Traditionnellement, il y a de nombreuses variables au sein des procédures de restauration indirecte, ainsi la qualité du résultat final est pratiquement imprédictible. Des erreurs pendant le processus de production peuvent s’ajouter les unes aux autres et conduire à un ajustage imprécis de la prothèse, voir même la refaire. En conséquence, des réglages fastidieux sont nécessaires.

Comme le montre l'expérience des laboratoires dentaires, l'intégration des technologies de production numérique est une étape décisive vers plus de prédictibilité.

Empreintes optiques

C'est ce qui s'est réellement passé dans l'esprit de ceux qui ont écouté le Président de séance le Dr Daniel Poticny (Texas) et les dix experts en dentisterie conservatrice, en prothèse et en implantologie. Durant leurs présentations, ils se sont focalisés sur les faits scientifiques et l'expérience clinique concernant l'utilisation des caméras intra-orales ainsi que sur les étapes ultérieures du flux numérique de la dentisterie restauratrice.

Le point de vue scientifique présenté par le Professeur Dr. Bernd Wöstmann (Gießen, Allemagne), les caméras intra-orales disponibles peuvent être recommandées pour les numérisations par quadrant pour produire une prothèse unitaire et des bridges. De plus, 3M™ True Definition Scanner offre une précision supérieure aux matériaux d’empreintes et aux autres caméras lorsqu'il s'agit d’enregistrer des arcades complètes. Cela a été révélé par le Dr. Jan-Frederik Güth (Munich, Allemagne) qui a présenté les résultats de son étude menée in vitro. Dans l'environnement clinique, les enregistrements d’arcades complètes sont déjà utilisés avec succès. Dans ce processus, la prédictibilité est assurée en raison de l'option de contrôle de la qualité de la préparation et de la réalisation d’un modèle entièrement numérique immédiatement après la prise d’empreintes.

Les caméras

Toutefois, avec la prise d’empreintes, le potentiel des caméras intra-buccales est loin d'être épuisé : le Prof. Dr. Albert Mehl (Zürich, Suisse) a démontré que le processus d’usure et les modifications parodontales peuvent être visualisées en superposant différents enregistrements (scans). Le Dr. Paulo Monteiro (Caparica, Portugal) a suggéré de garder les acquisitions de chaque patient dans une base de données numériques pour d’éventuelles restaurations futures et pour des recherches médico-légales.

Une porte vers la dentisterie "dentisterie minimale invasive"

En outre, les systèmes de prise d’empreintes numériques fournissent un accès direct à de nombreux matériaux innovants qui, à leur tour, permettent des restaurations de moins en moins invasives. Par exemple, une nouvelle classe de matériaux hybrides comme Lava™ Ultimate de 3M ESPE est devenue l'option préférée de nombreux orateurs lorsqu'il s'agit de restaurations fonctionnellement exigeantes. Le Prof. Dr. Stefan Koubi (Marseille, France) a montré qu'il utilise ce matériau élastique pour les patients avec une usure importante pour éviter de sacrifier la structure saine de la dent.

Une approche similaire a été adoptée par le Prof. Daniel Edelhoff (Munich, Allemagne). Il a présenté des cas cliniques de patients avec parafonction dues à une dysplasie cleidocraniale et des maladies parodontales qui ont été restaurées avec la Résine Nano-Céramique. Le Prof. Dr. Gerwin Arnetzl (Graz, Autriche) préfère utiliser pour la production et des couronnes sur piliers implantaires Lava Ultimate puisqu'il fonctionne comme un amortisseur du fait de sa forte résilience.

Guide pour le mode d’assemblage: scellement ou collage

Les recommandations sur la manière d’assembler les différentes sortes de restaurations CAD/CAM ont été données par le Prof. Dr. Claus-Peter Ernst (Mayence, Allemagne). Il a montré qu'en fonction de la résistance du matériau de restauration et de l'indication, un scellement conventionnel, par composite auto-adhésif ou par collage avec un composite de collage avec adhésif peuvent être nécessaires.

Combinaison de technologies numériques

Le Prof Daniel Wismeijer (Amsterdam, Pays-Bas), axé sur les autres technologies numériques a montré que face aux scanners, les CT scans, 3D technologies d'impression numériques, etc. , pourront bientôt être combinés avec les empreintes numériques. De cette façon, il sera possible de mettre en œuvre complètement des flux de productions numériques par exemple dans le domaine de l’implantologie. Pour une utilisation plus pratique, les technologies disponibles seront développées sur des applications smartphone comme illustré par le Dr Walter Devoto (Sestri Levante, Italie).

Dans la discussion finale, les conférenciers et les participants ont convenu qu'il y a de nombreux avantages résultant des procédés numériques. Afin de les exploiter, il est essentiel de ne pas attendre, mais de passer au numérique dès maintenant!
