Summary

This study tests a collagen-based bone graft material (Bio-Oss Collagen) for sinus augmentation in people with bone loss and missing teeth. The goal is to see if it helps grow enough bone to support a dental implant. The study involves 36 adults who need a single implant in the upper jaw and have limited bone height.
