Préparation pré-implantaire par comblement sinusien et gestion de ses complications: une étude rétrospective de 81 cas au CHU de Dijon

Abstract

Introduction: The restitution of bone volume by sinus floor elevation (SFE) or sinus lift is the reference technique for dental implant rehabilitation in the atrophic posterior maxilla. The objective of this study was to investigate the implant survival rate after SFE and describe the different complications and their management during this procedure. Materials and methods: A retrospective cohort study was conducted on all cases of SFE in the Odontology Department in Dijon between January 2005 and December 2014. Two procedures were recorded: the first with implant placement simultaneously with the SFE, and the second with implant placement secondarily. Results: Eighty-one SFEs were performed on 69 patients. Of these 81 SFEs, 163 implants were placed. Four implants had to be filed, all because of peri-implantitis. Nine cases of sinus membrane perforation were noted without impact on the implants. A case of significant resorption of the bone graft did not allow implant placement. No cases of surgical wound dehiscence, massive bleeding or fibrointegration were found. Conclusion: SFE is the first-line technique in the preparation of implants in the atrophic posterior maxilla. The correct management of complications ensures survival of the implant and prosthetic success.
