Guided Bone Regeneration in a Periodontally Compromised Individual with Autogenous Tooth Bone Graft: A Radiomics Analysis

Abstract

Background: Autogenous tooth bone graft material (AutoBT) has been advocated as a bone substitute when conducting alveolar ridge preservation. This study is aimed at using a radiomics approach in order to evaluate and testify whether AutoBT can stimulate bone growth during socket preservation in severe periodontal cases. Materials and Methods: For this study, 25 cases with severe periodontal diseases were selected. The patients ' AutoBTs were inserted into the extraction sockets and covered with Bio-Gide((R)) collagen membranes. 3D CBCT scans and 2D X-rays were taken of the patients before surgery and after 6 months post-surgery. For the retrospective radiomics analysis, the maxillary and mandibular images were compared in different groups. Maxillary bone height was analyzed at the buccal, middle, and palatal crest sites, while the mandibular bone height was compared at the buccal, center, and lingual crest sites. Results: In the maxilla, the alveolar height was increased by -2.15 +/- 2.90 mm at the buccal crest; -2.45 +/- 2.36 mm at the center of the socket, and -1.62 +/- 3.19 mm at the palatal crest, while the height of the buccal crest was increased by 0.19 +/- 3.52 mm, and the height at the center of the socket was increased by -0.70 +/- 2.71 mm in the mandible. The three-dimensional radiomics analysis demonstrated significant bone growth in the local alveolar height and high density. Conclusion: Based on clinical radiomics analysis, AutoBT could be used as an alternative bone material in socket preservation after tooth extraction in patients with severe periodontitis.
