Abstract
Aim: to analyze autologus dentin graft and its effectiveness in regeneration histologically.
Material and method: Three implants were placed in mandibular anterior region, for which dentin graft was obtained via grade III mobile teeth 35 and 44, they were extracted, cleaned of all the remnants then grinded into particle size of 300-1200 μm in a sterile grinding chamber. Autologous dentin graft was secured using membrane (Alloderm® GBR membrane, Biohorizons, Inc) with auto tracks. At 4 months during second stage, a bone core was obtained for histological examination using 3.2 mm trephine, the core site was then grafted with beta-TCP and was sutured, following which implant prosthesis was given to the patient.
Results: The surgical procedure and the healing was uneventful and patient did not show any discomfort. Histologically, at 4 months, bone grafted section shows the presence of dentin graft along with formation of new mature bone at the junction and vicinity of graft material.
Conclusion: autologous dentin graft shows promising results as a biocompatible regenerative material with low resorption rate and can be used as a substitute for autogenous bone grafts and synthetic bone grafts.
