Initial Stability of Posterior Maxillary Implants With Bicortical Fixation

NCT01237184 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 45

No results posted yet for this study

Summary

The primary purpose of this study is to

1. determine whether dental implant engaging both the alveolar crest cortical bone and sinus floor using vertical stopper drill and self-threading concept (bi-cortical fixation) increases initial implant stability compared to the short implants engaging only alveolar crest cortical bone (uni-cortical fixation) and/or ones engaging both crest and sinus floor but with green stick fracture (indirect sinus lift technique),
2. study whether different surgical techniques, residual bone height, bone density, and length and width of the implants used affect initial implant stability in posterior maxilla. In addition, this study will continue to
3. compare secondary implant stability of implants fixed bi-cortically, uni-cortically and with indirect sinus lift technique at 2nd stage surgery/6 month healing and 1 year follow-up from the restoration and
4. measure amount of endo-sinus bone formation from the 1- year follow up CT (computer tomogram) scan and evaluate safety and potential post-operative complications of bi-cortical fixation and indirect sinus lift technique reported throughout the follow up periods.
