Abstract
Missing of the upper posterior dentition can cause alveolar bone resorption & pneumatization of Maxillary sinus wall, which makes traditional implant placement impossible, The solution includes various methods to the posterior maxilla to provide adequate bone support for implant installation and long-term survival. -- sinus floor elevation, sinus-lift graft, inlay graft using LeFort I osteotomy, onlay graft, This is a clinical Sr. retrospective study on implant surgery & prosthodontic restoration with upper edentulous posterior jaw from Jan. 1990. to Jun. 1997 at implant clinic of Chonbuk National University Hospital. The results obtained were as follows: 1. Six hundred ninety-nine implants were placed on upper posterior jaw of two hundred seventeen patients, among them one hundred sixty-five implants were placed in forty-four patients with sinus lift. 2. The height of the remained alveolar bone was classified on the base of Misch's concept. This included seventy-nine SA-1s, ninety-seven SA-2s, sixty-five SA-3s and sixty SA-4s. 3. Ninety percent of implants were successfully integrated in non-grafted area and eighty-seven percent of implants were successully integrated in sinus lift area.
