Derived Dentin Graft as Autologous Bone Regeneration in Implant Surgery: A Histological and Radiographic Investigation

Abstract

Background: This study has been conducted to evaluate the dentin regeneration potential as an autologous graft material for the preservation of the bone volume in the post-extraction socket. Tooth Transformer has been used as the device required to demineralize the dentin got from the extracted elements, which led to obtaining a granular material rich in collagen and growth factors. Methods: All 8 patients selected for the study underwent two surgical procedures. During the first surgery, the affected elements have been extracted, the Tooth Transformer protocol has been run, and the material has been grafted into the existing bone defects and post-extraction socket. After three months, the biopsy of the regenerated areas has been performed and the implants required for prosthetic rehabilitation were placed in the same site. For two of the 8 patients, the implant has been placed with the support of a surgical guide. Result: CBCT and histological analysis’ results after 3 months confirmed the actual replacement of grafted material and the regeneration of bone tissue suitable for implant rehabilitation. Conclusion: Thus, the Tooth Transformer proves to be an effective device to produce an innovative autologous material from dentin, which is capable of predictable viable bone tissue regeneration able to support prosthetic implant rehabilitation in edentulous sites.
