Abstract

The aim of this study was to evaluate the clinical results of implants which were installed with maxillary sinus elevation using outfracture osteotomy. 80 patients with atrophic posterior maxilla were selected for this retrospective clinical study. The mean follow-up period was 20.3 months(ranged from 12 months to 46 months).

1. Unilateral sinus elevation were performed in 75 patients and bilateral sinus elevation were performed in 5 patients.
2. The sinus elevation and simultaneous implant installation was performed in 60 sinuses and 121 implants were installed.
The sinus elevation and delayed implant installation was performed in 25 sinuses and 61 implants were installed. The average healing period after sinus elevation was 6.8 months in delayed implant installation.
3. Some complications arise, such as swelling, perforation of sinus membrane, ecchymosis, wound dehiscence and infection. 2 implants were removed in the infected sinus.
4. The survival rate of implants with maxillary sinus elevation using outfracture osteotomy was 98.9%.

This results indicate that the outfracture osteotomy to maxillary sinus elevation is a acceptable method at atrophic maxillary posterior area.
