The effectiveness of autologous demineralized tooth graft for the bone ridge preservation: a systematic review of the literature

Resorption of alveolar ridge after tooth extraction often compromises dental implant placement and esthetic. Alveolar ridge preservation is a common procedure performed in order to preserve the pontic site for a prosthetically ideal position. This procedure has already become an indisputable need. Tooth matrix as bone substituted material poses osteoconduction and osteoinduction properties and as autologous graft, this material is free of antigenic reaction. This biomaterial allows the threedimensional reconstruction of the bone, is easy to prepare and has a low cost. The aim of this review is to summarize and put in evidence the properties of tooth as bone substitute and its use in alveolar ridge preservation.
