Abstract

Background: Bone loss following impacted 3rd molar extractions not only lead to clinical attachment loss, deep periodontal pockets of adjacent molar, but also increases the risk of angle fracture. Guided bone regeneration with the mineralized cancellous allograft material and resorbable collagen membrane demostrates to be able to reduce those unfavorable issues. Objectives: To evaluate the healing of 2nd molar’s periodontal tissue of the adjacent after surgical extraction impacted mandibular 3rd molar followed by Guided bone regeneration with mineralized cancellous allograft and resorbable collagen membrane. Materials and methods: A Cross-sectional study was conducted on 22 patients who had their impacted mandibular 3rd molars removed from 2021 to 2023 at Can Tho University of Medicine and Pharmacy Hospital. Inclusion criterias were: partial erupted lower 3rd molar, distance from Cemento-enamel junction to alveolar bone  crest on the distal aspect of the adjacent 2nd molar ≥ 4mm measured on radiographs. The pocket depth  ≥ 5mm probed on 2 location (distolingual and distobuccal) of lower 2nd molar. Results: The periodontal health of the second molars was found to improve after 3rd molar removal in all clinical parameters. The pocket depth was reduced 2.02±0.69 at 6 month. The plaque index and gingival index coded as 0 (healthy) or 1 (minor problems). The alveolar bone height measured on radiographs was significantly gained 3.73±1.08, the average of bone density in grafted area in 3 months (1323.95±57.40 HU) and 6 months (1370±51.57 HU). Conclusion: Guided bone regeneration treatment using mineralized cancellous allograft and resorbable collagen membrane results in increasing the efficiency of wound healing, pocket depth reduction and bone height gain.
