摘要
目的 探究光纤内镜辅助穿牙槽嵴上颌窦底提升同期种植的临床效果.方法 选取2017年9月至2018年9月于广州医科大学附属口腔医院种植科行冲顶法穿牙槽嵴上颌窦底提升同期种植的35名患者(共51颗种植体)作为研究对象.术中采用光纤内镜直视对比捏鼻鼓气法检查上颌窦黏骨膜完整性,探讨牙槽骨骨质类型、上颌窦底骨皮质厚度、上颌窦底黏骨膜厚度和窦底提升高度与上颌窦黏骨膜穿孔的关系,并探讨上颌窦黏骨膜穿孔对术后6个月时种植体稳定系数(implant stability quotient,ISQ)的影响.结果 51例穿牙槽嵴上颌窦底提升中以捏鼻鼓气法检出上颌窦黏骨膜穿孔2例,内镜辅助下检出穿孔10例,结果具有显著差异(P=0.013).上颌窦黏骨膜穿孔与牙槽骨骨质类型、上颌窦底黏骨膜厚度(＜3 mm)和窦底提升高度皆无明显相关,而与窦底骨皮质厚度显著相关(P=0.001);上颌窦黏骨膜穿孔直径＞2 mm时需更长愈合时间以获得理想的ISQ.结论 穿牙槽嵴上颌窦底提升中,光纤内镜可显著提高上颌窦黏骨膜穿孔检出率,利于术者判断窦底黏膜的情况以及选择更为合适的修复时机.
Abstract
Objective To investigate the clinical effect of fiber-optic endoscope-assisted transalveolar technique for sinus floor elevation with simultaneous implant placement.Methods 35 patients who visited the Affiliated Stomatology Hospital of Guangzhou Medical University from September 2017 to December 2018 were selected as research subjects.A total of 51 transalveolar sinus floor elevations with simultaneous implant placements were performed.The integrity of the sinus floor mucoperiosteum was examined intraoperatively using a fiber-optic endoscope with direct visualization compared with the Valsalva test.The relationship between maxillary sinus mucoperiosteal perforation and the following factors:alveolar bone quality(Lekholm and Zarb classification),sinus floor bone cortical bone thickness,sinus floor mucoperiosteal thickness,and sinus floor elevation height was also explored.The effect of perforation of the mucoperiosteum on the implant ISQ at 6 months postoperatively was also investigated.Results Among the 51 cases of transalveolar sinus floor elevation,only 2 cases of mucoperiosteal perforation were detected by the Valsalva test,while 10 cases of perforation were detected by the endoscope,and the results showed a significant difference(P=0.013).There was no significant correlation between sinus mucoperiosteal perforation and alveolar bone quality classification,sinus floor mucoperiosteal thickness(＜3 mm),or sinus floor elevation height,while there was a significant correlation with sinus floor cortical bone thickness(P=0.001).Maxillary sinus mucoperiosteal perforations with a diameter of＞2 mm required a longer healing time to obtain the ideal implant ISQ.Conclusion The fiber-optic endoscope can significantly improve the detection rate of sinus mucoperiosteal perforation in transalveolar sinus floor elevation,which is helpful for the operator to judge the condition of the sinus floor mucoperiosteum and to choose a more appropriate timing for restoration.
