摘要
目的分析后颌骨引导骨再生（GBR）联合种植体植入后增强骨的稳定性及其影响因素。材料与方法102例患者共165颗种植体。记录一般信息、种植体周围软组织参数和并发症。收集术前（T0）、术后即刻（T1）、愈合后（T2）和最新随访（T3）的锥形束计算机断层扫描图像。评估颊骨宽度、高度、骨距（BD）和增强骨体积（ABV）。根据BD值将骨增强范围分为内轮廓（IC）组和外轮廓（OC）组。分析影响增强骨体积吸收率的因素。结果随访12 ~ 88个月，平均ABV%为47.56%±20.29%，主要发生在T1和T2之间。与IC组相比，OC组ABV%较高(p <；0.001)。IC组和0 ~ 1 mm OC组的BD < 0, 1 ~ 2 mm OC组和1 ~ 2 mm OC组的BD < 0；2 mm OC组在T3时接近0。骨增强范围(p <；0.001)，不含缺陷（p = 0.001）和2mm愈合基台（p = 0.008）显著影响ABV%。结论GBR与种植体同时植入后颌骨可提供可预测的增强骨体积稳定性。OC移植物向个体表型尺寸吸收，而1-2毫米的过度增大可能会优化轮廓维持。非包含缺陷损害了体积稳定性，而2毫米愈合基台与盖螺钉相比增强了稳定性。
Stability of Augmented Bone and Its Influencing Factors After Simultaneous Guided Bone Regeneration With Implant Placement in the Posterior Mandible: A Retrospective Study
Aim
To analyse the stability of augmented bone and its influencing factors after simultaneous guided bone regeneration (GBR) with implant placement in the posterior mandible.
Materials and Methods
A total of 165 implants in 102 patients were included. General information, peri-implant soft-tissue parameters and complications were recorded. Cone-beam computed tomography images at preoperative (T0), immediate postoperative (T1), post-healing (T2) and the latest follow-up (T3) were collected. Buccal bone width, height, bone distance (BD) and augmented bone volume (ABV) were assessed. Bone augmentation range was classified into inside-contour (IC) group and outside-contour (OC) group based on BD values. Factors influencing the augmented bone volume resorption rate (ABV%) were analysed.
Results
During the follow-up period of 12–88 months, the mean ABV% was 47.56% ± 20.29%, predominantly occurring between T1 and T2. The OC group showed higher ABV% compared to the IC group (p < 0.001). BD of the IC and 0–1 mm OC groups was less than 0, while BD of the 1–2 and > 2 mm OC groups was near 0 at T3. Bone augmentation range (p < 0.001), non-contained defects (p = 0.001) and 2-mm healing abutments (p = 0.008) significantly influenced ABV%.
Conclusions
Simultaneous GBR with implant placement in the posterior mandible provided predictable volumetric stability of the augmented bone. OC grafts resorbed towards individual phenotypical dimensions, whereas 1–2 mm over-augmentation might optimise contour maintenance. Non-contained defects compromised volumetric stability, while the 2-mm healing abutments enhanced stability compared to cover screws.
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.
