Abstract
OBJECTIVES: The purpose of this study was to evaluate the stability of tapered resorbable blasting media surface implants in the posterior maxilla. STUDY DESIGN: From September 2008 through January 2010, 20 patients (9 men, 11 women) who were treated with tapered GS III implants at Seoul National University Bundang Hospital were identified. Thirty-eight implants (14 premolar and 24 mol/L) were placed in maxillary posterior areas. RESULTS: The patients' mean age was 52.1 years, and the mean follow-up period was 12.6 months after final prosthesis delivery. The implant length was 11.8 ± 1.4 mm with a diameter of 4.6 ± 0.5 mm. The 1-year survival rate was 97.4%, and the success rate was 94.7%. The implant stability quotient value at implant placement was 63.6 and 74.4 at the second surgery, which indicated a significant difference. There was no significant difference in crestal bone loss according to implant diameter or length or sinus bone graft. CONCLUSIONS: This study showed the favorable clinical outcome of tapered implants that were placed in the maxillary posterior area.
