Introduction: Autogenous teeth have the potential to be employed as a bone graft material that is both osteoconductive and osteoinductive. Dentin and bone have comparable biochemical features (80% hydroxyapatite crystals and 20% type I collagen), and dentin also includes growth factors such as insulin-like growth factor II (IGF-II), transforming growth factor (TGF-b), and bone morphogenic protein (BMP).
Objectives: the aim of this study was to evaluate socket preservation using a combination of both socket shield technique and grafting. Alloplastic bone graft was compared to Autogenous graft of dentin (prepared from the palatal part of the tooth) using a split-mouth design.
Materials and methods: Seven patients received maxillary implants in previously preserved extraction sockets using alloplastic graft material with socket shield technique on the right side and Autogenous dentin graft with socket shield on the left side. Bone dimensional changes, bone density and implant stability were evaluated.
Results: Sockets preserved using both Socket Shield Technique and Autogenous Dentin graft showed a statistically significant higher Implant stability and higher Bone Density than sockets of the contralateral side preserved with socket shield and alloplastic graft material.
Conclusions: Autogenous dentin graft, combined with Socket Shield Technique gave very promising outcomes as a dual socket preservation method.
