title: [A clinical retrospective study of 10 years implant results].
abstract: OBJECTIVE
  To evaluate ten years clinical results of dental implant treatment.
  
  
  METHODS
  A total of 5,590 endosseous implants were consecutively placed from Aug. 1994 to Aug 2004 in Center of Implantation, Peking University School and Hospital of Stomatology. Among them, 161 were Brånemark implants, 1,436 were Frialit-2 implants, 1,012 were IMZ implants, 767 were Ankylos implants, 2,189 were Camlog implants, and 25 were Komet implants. A total of 2,629 prostheses were delivered, including 2,314 fixed prostheses and 315 implant-supported removable dentures. The patient age range was between 17 and 82. The mean follow-up time was 77.2 months (7 to 121 months). Clinical examination and X-ray films were conducted. The results were evaluated with Wheeler's survival criteria.
  
  
  RESULTS
  With the final prostheses, 2,624 patients were satisfied. Five patients were unsatisfied with the prostheses. With refabricating the prostheses, 4 patients were satisfied and one expressed as acceptable. Peri-implantitis was observed in 178 implants of 105 cases. Prostheses loose was observed in 21 cases and fracture in 4 cases. Ceramic crack was observed in 51 cases. The documented implants lost were 68. The implant survival rate was 96.7% according to Wheeler's survival criteria.
  
  
  CONCLUSIONS
  Implant prostheses were with high satisfaction. The implant survival rate was as highly as 96.7%. Implant prostheses were indicated for almost all the partial and complete edentulous cases due to modern implant surgical technique.
