Abstract
RÉSUMÉ
Les auteurs rapportent le cas d’une patiente âgée de 24 ans qui a reçu un implant en titane. Après quatre ans de suivi, une légère décoloration grisâtre était visible au niveau de la gencive marginale, indiquant la présence du titane sous la muqueuse. Les auteurs rapportent également celui d’un patient de 46 ans ayant été réhabilité avec un implant en zircone. Après 4 ans de suivi, aucune trace de coloration grisâtre n'était visible et l'intégration esthétique était optimale. Dans les deux cas étudiés, les implants ont présenté une stabilité fonctionnelle. L'implant en zircone a montré une meilleure intégration esthétique par rapport à l'implant en titane, confirmant ainsi l'avantage potentiel de la zircone pour les piliers implantaires en termes d'esthétique.
ABSTRACT
The authors report the case of a 24-year-old female patient who received a titanium implant. After four years of follow-up, a slight greyish discoloration was visible in the marginal gingiva, indicating the presence of titanium under the mucosa. The authors also report the case of a 46-year-old patient who was rehabilitated with a zirconia implant. After 4 years of follow-up, no traces of greyish discoloration were visible and aesthetic integration was optimal. Conclusion. In both cases studied, the implants showed functional stability. The zirconia implant showed better aesthetic integration than the titanium implant, confirming the potential advantage of zirconia for implant abutments in terms of aesthetics.
