Biomolecular Mechanisms and Case Series Study of Socket Preservation with Tooth Grafts

The purpose of this research was to assess the effectiveness of an innovative medical device capable of extracting tooth graft materials directly from the patient’s own teeth. Twenty consecutive tooth grafting procedures were conducted, with an average follow-up period of 18 months. Methods: Twenty patients requiring tooth extraction underwent socket preservation utilizing the extracted tooth as the grafting material. Results: After a 4-month healing period, the defects were significantly filled with newly formed hard tissue. Subsequently, bone biopsies were performed during dental implant placement to evaluate histological outcomes. The tissue exhibited a similar density to medium-density bone, displaying a homogeneous and uniform appearance without any visible signs of inflammation. The post-operative healing phase was free from infective complications or indications of graft particles within the regenerated bone structure. The histomorphometric analyses revealed the following results: bone total volume, BV% 52.6 ± 13.09, vital bone VB% 40.39 ± 15.86, residual graft % 12.20 ± 12.34. Conclusion: The study demonstrated positive bony healing in guided regenerative surgery procedures using autologous tooth grafts. However, further research with an extended follow-up period is necessary to thoroughly assess the potential of demineralized dentin autografts.
