New Bone Formation Using an Extracted Tooth as a Biomaterial: A Case Report with Histologic Evidence.

This case report aims to demonstrate the regenerative potential of particles obtained from a crushed extracted tooth. Following tooth removal, the clean root was ground and the dentin and cementum granules were grafted into a fresh extraction socket for a ridge preservation procedure. After 24 weeks, a successful implant placement was allowed. Tissue healing was evaluated by histologic and radiologic analysis. The volume of the ridge was preserved. Histologically, a dentin-bone complex was reported. New bone formation was evident, with an intimate contact between bone and both dentin/cementum. This novel procedure suggests the use of tooth particles as graft material.
