Study Summary

The purpose of this study is to evaluate the survival rate of 5 mm short implants compared to longer implants (10 mm) placed in sinus-grafted sites. Primary aim: Compare bone loss between the two groups Secondary aim: Compare surgical time and patient-reported outcomes (satisfaction and post-operative pain)

Primary Outcome

Comparing mesial-distal (M-D) bone loss between the two groups. This will be measured in millimeters using standardized radiographs of the implant site at the screening visit, surgical visit, 4 months post-op, 5 months post-op, 12 months post-op, and 24 months post-op visits.
