Dimensional Changes After Different Alveolar Ridge Preservation Techniques for Posterior Region: A Randomised Controlled Clinical Trial
Aim
Alveolar ridge preservation (ARP) after tooth extraction aims to maintain ridge dimensions for future implant placement. However, limited evidence is available for posterior sites. We evaluated the dimensional changes in posterior extraction sockets using four approaches: modified free gingival graft (MFGG); MFGG with xenograft (MFGG + XG); guided bone regeneration with titanium membrane and xenograft (TM + XG); and unassisted socket healing (USH).
Materials and Methods
Patients requiring posterior tooth extraction were randomly assigned to one of four groups (n = 22/group). Cone-beam computed tomography (CBCT) was performed immediately after operation and at 6 months to assess vertical and horizontal alveolar ridge changes and implant-related outcomes.
Results
Significant dimensional changes occurred in all groups (p < 0.05). The TM + XG and MFGG + XG groups showed better preservation of vertical ridge dimensions than the USH and MFGG groups (p < 0.05). Horizontal reductions were significant in all groups (p < 0.05). USH presented the highest sinus floor elevation rate (67% of maxillary cases) and the most frequent use of short implants (< 8.5 mm; 71%). Postoperative pain was significantly greater in the MFGG groups compared to the USH group (p < 0.05).
Conclusion
Bone grafting with MFGG or a titanium membrane enhanced ridge preservation and reduced the need for additional surgery compared to USH.
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.
