Impact of Socket Preservation Technique Using Autogenous Dentin Graft and Hydroxyapatite Crystals on Primary Stability of Dental Implants in Same Individuals: A Pilot Study

A pilot study was conducted to analyze and compare the stability of dental implants using 2 different graft materials (autologous dentin graft and an alloplastic hydroxyapatite [HA] crystal) in the same patient. As far as we know, this study is first of its kind where socket preservation has been done using 2 different grafts in the same patient. Ten patients undergoing extraction of at least 2 teeth were selected. Atraumatic extractions were performed. Out of the 2 extraction sockets, 1 was grafted with autogenous tooth graft and other with HA crystals. Computed tomography scan was performed 3 months after grafting to evaluate bone mineral density. Primary implant stability was measured using resonance frequency analysis. It was observed that among both sites, autogenous tooth grafted sites showed better results.
