【摘要】：目的:评价牙槽突扩张联合引导骨再生术(GBR)和植骨术同期植入ITI种植体的远期效果。方法:回顾分析对55名患者(男35名,女20名)行牙槽突扩张联合GBR植骨术,同期植入ITI Straumann种植体83颗的临床效果。结果:患者平均年龄36.3岁(18~60岁),平均骨愈合时间6.9个月(4.0~20.7个月)。完成56例修复体,其中种植单冠28例,种植联冠8例,种植单端桥5例,种植固定桥13例,种植支持式覆盖义齿2例。修复完成后每年定期随访,包括临床检查和X线测量,累计观察期8年。2名患者(3.6%)术中发生唇侧骨板骨折。4名患者(7.5%)修复后失访。49名患者平均随访时间3.1年(0.5~7.5年),种植体8年累计存留率为100%。种植体平均边缘骨高度为颈缘下2.57 mm。10例修复体发生修复并发症。结论:针对严重牙槽突宽度骨量不足的患者,牙槽突扩张联合GBR植骨牙种植术是一种可行的种植方案。
[Abstract]:Objective: to evaluate the long-term effects of alveolar process dilation combined with guided bone regeneration (GBR) and bone graft implantation with ITI implants. Methods: 55 patients (35 males and 20 females) were treated with alveolar process dilation and GBR bone grafting. 83 ITI Straumann implants were implanted simultaneously. Results: the average age of the patients was 36.3 years (1860 years) and the average bone healing time was 6.9 months (4.0 ~ 20.7 months). 56 cases of prostheses were completed, including 28 cases of single implant crown, 8 cases of implant combined crown, 5 cases of implant single end bridge, 13 cases of implant fixed bridge, 2 cases of implant supported overdenture. The repair is followed up regularly every year, including clinical examination and X-ray measurement. The cumulative observation period was 8 years. 2 patients (3.6%) developed labial bone plate fracture during operation. 4 patients (7.5%) lost their visit after repair. 49 patients were followed up for an average of 3.1 years (0.5 ~ 7.5 years). The accumulative survival rate of implant was 100%. The mean marginal bone height of the implant was 2. 57 mm.10 below the cervical margin. Conclusion: alveolar process dilation combined with GBR implantation is a feasible implant for patients with severe alveolar process width deficiency.
