Abstract
Aim: To compare the dimensional stability of a self-retaining synthetic block bone (srBB) and synthetic bone particles (SBP) for alveolar ridge augmentation (ARA) in damaged extraction sockets.
Materials and methods: ARA was randomly performed in two centres on 57 participants presenting damaged extraction socket in a non-molar tooth: (i) srBB and collagen membrane (srBB group, n = 29) or (ii) SBP and collagen membrane (SBP group, n = 28). Cone beam computed tomography (CBCT) was performed immediately after ARP (baseline, T0) and at 6 months (T1). T0 and T1 CBCTs were superimposed, and horizontal widths (H0-H5), vertical heights and volume changes were assessed using t-test.
Results: Due to wound dehiscence, srBB was removed in 10 patients. The change in horizontal width at the most coronal level (H0) was significantly lower for srBB compared to SBP (srBB: 0.8 ± 1.0 mm; SBP: 1.9 ± 2.2 mm, p < 0.05). Significantly less volume decrease was seen at the bucco-coronal level for srBB (srBB: 3.2 ± 0.6 mm3; SBP: 10.4 ± 2.3 mm3, p < 0.05).
Conclusion: Compared to synthetic bone particles, synthetic bone blocks have the potential to more effectively augment and maintain the coronal horizontal dimension and width of damaged extraction sockets for up to 6 months. However, this advantage is offset by their relatively high rates of early wound dehiscence.
Trial registration: Korean Clinical Research information service (CRIS) (KCT0005462).
期刊介绍：
Journal of Clinical Periodontology was founded by the British, Dutch, French, German, Scandinavian, and Swiss Societies of Periodontology.
The aim of the Journal of Clinical Periodontology is to provide the platform for exchange of scientific and clinical progress in the field of Periodontology and allied disciplines, and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope.
The Journal publishes original contributions of high scientific merit in the fields of periodontology and implant dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, and the comprehensive rehabilitation of the periodontal patient. Review articles by experts on new developments in basic and applied periodontal science and associated dental disciplines, advances in periodontal or implant techniques and procedures, and case reports which illustrate important new information are also welcome.
