摘要

摘牙后牙槽嵴保存(ARP)的目的是保持牙槽嵴的尺寸,以便将来种植体的放置。然而,关于后侧部位的证据有限。我们采用改良游离龈移植(MFGG)四种方法评估后牙槽位的尺寸变化;MFGG与异种移植(MFGG + XG);钛膜异种骨移植引导骨再生(TM + XG);和无辅助窝骨愈合(USH)。材料与方法将需要拔牙的患者随机分为4组(n = 22/组)。术后立即进行锥形束计算机断层扫描(CBCT),并在6个月时评估垂直和水平牙槽嵴的变化和种植体相关的结果。结果各组患者均出现显著的维数变化(p < 0.05)。TM + XG和MFGG + XG组比USH和MFGG组更能保留垂脊尺寸(p < 0.05)。各组水平降低均显著(p < 0.05)。上颌USH的窦底抬高率最高(67%),使用短种植体最多(< 8.5 mm;71%)。MFGG组术后疼痛明显大于USH组(p < 0.05)。结论与USH相比,MFGG或钛膜植骨可增强骨脊的保存,减少了额外手术的需要。临床试验注册号:NCT06081296。

Dimensional Changes After Different Alveolar Ridge Preservation Techniques for Posterior Region: A Randomised Controlled Clinical Trial

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.
