Auto-tooth bone graft material for reconstruction of bone defects in the oral region: case reports

We present some clinical cases of autogenous tooth graft - a modern method in which the extracted teeth are processed into a demineralised dentin matrix (DDM) and are then immediately transplanted into the post-extraction sockets or bone defects.We included patients with jaw lesions due to chronic inflammatory conditions, cystic formations, or peri-implantitis. After removing the pathological processes and tissues, we performed curettage with an Er-YAG laser and treated the bone structures in the borderline area. Then auto-tooth bone (ATB) graft material was applied. The clinical results showed favourable wound healing and good bone integration of implants. Radiological studies showed stimulation and acceleration of bone regeneration with alveolar crest resorption of graft material of no more than 10%. Histological examination found new bone formation which was induced by the osteo-inductive material.On the basis of the clinical outcomes and the favourable healing process with a very good bone integration of the DDM, we can recommend this method as an option for bone defect reconstruction. The satisfactory quantity (up to 3 grams per molar) and quality of the demineralised dentin matrix determine a relatively low cost of bone grafting.
