Shorter implants may spare patients from bone grafting surgery
NCT ID NCT07417293
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether very short dental implants work better than longer implants that require bone grafting in people with bone loss in the upper jaw. About 35 adults will be randomly assigned to one of the two treatments. The main goal is to see which approach leads to higher patient satisfaction and fewer complications.
