Résumé -IntroductionQuatre implants furent déposés pour cause de péri-implantite. Neuf cas de perforation de membrane sinusienne peropératoire furent notés sans incidence sur les implants. Un cas de résorption importante du greffon a empêché la pose d'implants. Aucun cas de désunion de voie d'abord, d'hémorragie massive ou de fibro-intégration ne fut constaté. Conclusion : La GCS reste la technique de première intention dans la préparation préimplantaire des secteurs postérieurs maxillaires édentés. La correcte gestion des complications assure la survie implantaire et la réussite prothétique.Abstract -Retrospective study of sinus lift complication: about 81 cases treated at Dijon University Hospital. 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 firstline technique in the preparation of implants in the atrophic posterior maxilla. The correct management of complications ensures survival of the implant and prosthetic success.
Résumé -Introduction :Les lymphomes primitifs osseux mandibulaires ont été décrits pour la première fois par Parker et Jackson. Les lymphomes constituent le deuxième cancer de la tête et du cou, après les carcinomes épidermoïdes. Les localisations mandibulaires sont rares et ne représenteraient que 0,6 % des cas. Observation : Nous exposons, à travers une observation, les caractéristiques cliniques et radiologiques du lymphome mandibulaire ainsi que ses modalités de prise en charge chez une patiente de 50 ans. Le traitement est médical par une chimiothérapie. Discussion : Les lymphomes de la tête et du cou sont presque toujours des lymphomes B à grandes cellules. Ils peuvent être confondus avec une pathologie odontogène. Le chirurgien oral ne doit pas ignorer cette pathologie dont le taux de rémission complète est de 60 à 80 % à un an.Abstract -Non-Hodgkin lymphoma of the mandible for teeth mobility: a case report. Introduction: Mandibular bone primary lymphoma was described for the first time by Parker and Jackson. Lymphoma is the second most common cancer of the head and neck after squamous cell carcinoma . Mandibular localizations are rare and represent only 0.6 % of cases. Observation: We describe the clinical and radiological characteristics of mandibular lymphoma and its management in a 50-year-old patient. The medical treatment was chemotherapy . Discussion: Head and neck lymphoma is almost always large B lymphoma cells. Oral surgeons need to know this pathology, which can be confused with odontogenic disease. The complete remission rate is 60 to 80 % at one year.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
