Socket preservation or guided bone regeneration - a case report

Abstract

The greatest challenge of modern implantology is the loss of bone tissue in esthetic region of maxilla and mandible. Significant bone changes caused for example by cysts, unerupted teeth or traumatic extraction often provoke bilateral or trilateral bone defects. Thanks to the possibility of applying demineralized dentin and dentin blocks gained from extracted teeth of the patient, it is possible to successfully regenerate bone tissue especially in the esthetic zone.

Aim: The aim of the study was to present a case of a patient who underwent bone augmentation for implantation. In addition, a review of the literature illustrating the effectiveness of autogenous bone graft material derived from ground teeth in augmentation procedures was performed.

A case report: The paper presents a case of a 26-year-old man in whom bone defect was augmented with material derived from dentin blocks and partially demineralized dentin processed in the BonMaker device after extraction of the root of tooth 11. A systematic review of literature was conducted analyzing articles published between 1975 and 2020. From 80 articles, 25 were selected for this study.

Conclusions: The presented case and the systematic review of literature indicate that tooth-derived bone graft material prepared from extraction can effectively restore alveolar bone defect. The results we get so far are very satisfying. Further studies should be performed to confirm the osteogenic effects and safety use of this tooth based graft material.
