Abstract

PURPOSE
The purpose of this study was comparison of survival rate of implant as two sinus elevation techniques and when window opening procedure had done it was comparison of survival rate of implant between the procedure of implantation after 6 month of sinus elevation to allow healing period and that of implantation with sinus elevation simultaneously. MATERIAL AND METHODS: All 79 of patients treated at DanKook University Dental Hospital Dept. of Periodontics for 164 implantation of maxillary posterior edentulous area with sinus elevation. Sinus elevation technique was divided of the technique : Osteotome technique and window opening technique. RESULT: 14 implants among 96 implants was failed implants of using osteotome for sinus elevation whereas one implant of 68 implants was failed of using window opening technique.
CONCLUSION
Window opening technique had higher survival rate than osteotome technique. In case of window opening, there was no significant difference of immediate implantation and delayed implantation.
