Abstract
- The authors performed the clinical and radiographic evaluation in the 29 patients with sinus bone graft and Osstem(R) implant placement between Sep 2003 and Jan 2006 and got the following results. 1. Fifteen complications developed in the 13 patients. Intraoperative sinus membrane perforation and postoperative maxillary sinusitis developed frequently. 2. The mean preoperative residual alveolar bone height was 4.5 mm, postoperative height 18.5 mm, height 1 year after operation 16.9 mm. 3. Three primary osseointegration failures(3.7 percent) developed in 3 patients. 4. The survival rate of prosthodontics was 100 percent at the final follow up. The mean marginal bone resorption around the implants was 0.69 mm 1 year after prosthodontic loading. Marginal bone resorption more than 1.5 mm developed in nine implants and the success rate was 88 percent.
