Introduction This study was intended to determine the survival rate of implants placed in grafted maxillary sinuses and compare the results obtained with timing of implant placement under 4mm residual bone height.
Materials and Methods: I retrospectively reviewed the medical records of 52 cases of implants from 24 patients, who were treated at gong-dan dental clinic from April 2006. Simultaneous implant placement after sinus bone graft were 40 cases, and number of delayed protocol were 14 cases.
Result: The survival rate of simultaneous protocol group was 95% and the survival rate of delayed protocol was 100%.
Conclusion: It is considered that the clinical outcome of sinus bone graft and simultaneous implant placement is similar to thedelayed placement. So, simultaneous implantation is recommended if primary stability is obtained although under 4mm residual bone height.
