Impact of a Alveolar Ridge Preservation Technique on the Need of Performing Guided Bone Regeneration for Dental Implant Placement

Impact of Alveolar Ridge Preservation on Optimal Implant Placement

The aim of this study is to investigate how a socket preservation procedure may reduce the need of guided bone regeneration surgery after tooth extraction and facilitate the placement of a dental implant in the optimal, prosthetic-driven position.

The main gol of the study is to assess the efficacy of a socket preservation procedure in reducing the need of additional surgeries in order to augment alveolar bone volume before placing a dental implant in optimal position. Bone volume at 6 months will be compared to initial volume in order to assess volume variations and how they affect the positioning of a prosthetically driven, implant.
