Resorbable vs Non-resorbable Bone Substitute at Immediate Post-extractive Single Implants

Summary

This study compares two bone graft materials used when placing a dental implant right after tooth removal. One graft fully dissolves (GTO®), the other only partly (Apatos®). The goal is to see which one better preserves bone and improves appearance around the implant.
