【摘要】：目的评价上颌窦侧壁小窗口窦底外提升同期种植体植入在上颌后牙区骨量不足中应用的近期临床效果。方法 7例(共8侧)上颌后牙缺失患者,上颌窦底与牙槽嵴顶之间的剩余牙槽骨高度均5 mm(平均3.7 mm),行上颌窦侧壁小窗口窦底外提升同期植入种植体16枚,术后6个月上部结构修复,随访6~24个月,平均(11.6±5.7)个月。观察种植体存留率、种植体周围骨结合和骨量改变情况,以及上颌窦底外提升术的并发症。结果观察期内本组种植体留存率为100%,16枚种植体均成功负载,骨结合状况良好,无不良自觉症状,本组病例术中未出现窦底黏膜穿孔破裂,仅有2例术后轻度颌面部肿胀。比较术后当天与术后6个月X线显示上颌窦内种植体周围骨高度平均增加10.1 mm;边缘骨丧失平均0.4 mm。结论上颌窦侧壁小窗口窦底外提升同期种植体植入是上颌后牙区剩余牙槽高度严重不足种植修复的有效解决方案,操作简便安全、并发症发生率低,减少手术及诊疗次数,缩短治疗周期,近期临床效果好,值得临床进一步研究和推广应用。
[Abstract]:Objective to evaluate the clinical effect of simultaneous implants implantation in the maxillary posterior dentition region with osseous deficiency in the lateral wall of maxillary sinus. Methods in 7 patients (8 sides) with maxillary posterior teeth missing, the height of residual alveolar bone between the maxillary sinus floor and the alveolar crest was 5 mm (mean 3.7 mm). 16 implants were implanted at the same time. The superstructure was repaired 6 months after operation and followed up for 6 ~ 24 months, with an average of 11.6 卤5.7 months. The survival rate of implants, the changes of osseous binding and bone mass around implants, and the complications of extramaxillary sinus lifting were observed. Results during the observation period, the retention rate of the implants was 100 and 16 implants were successfully loaded, the osseous bond was good, and there was no bad conscious symptom. There was no perforation and rupture of the mucosa in the sinus floor, only 2 cases had slight maxillofacial swelling after operation. The height of bone around implants in maxillary sinus was increased by 10.1 mm on the same day and 6 months after operation, and the average loss of marginal bone was 0.4 mm. Conclusion simultaneous implant implantation in lateral wall of maxillary sinus is an effective solution to the severe shortage of residual alveolar height in the maxillary posterior region. It is simple and safe to operate, with low incidence of complications, and reduces the frequency of operation and diagnosis and treatment. Shorten the treatment cycle, clinical effect is good in the near future, worthy of further clinical research and application.
