Abstract

Bone grafting uses a wide range of materials derived mainly from exogenous sources. Autogenous teeth are often used fresh or fixed with alcohol for later use. Proposed here is a method of using cryogenically preserved autogenous extracted teeth, which could be macerated after thawing. This method avoids the possibility of tissue being denatured by alcohol and preserves intact all calcified structures for optimal bone grafting success.
