新型上颌窦提升工具在开窗式上颌窦外提升术中的应用效果

摘要/Abstract

摘要： 目的研究新型上颌窦提升工具在开窗式上颌窦提升术中的应用效果。方法对34例患者共51颗上颌磨牙缺失病例进行开窗式上颌窦提升术，其中22例患者使用新型上颌窦提升工具作为实验组，12例患者使用普通球钻作为对照组，进行上颌窦开窗，黏膜提升至足够高度，填人工骨粉，同期植入种植体，人工生物膜覆盖。比较2组术中上颌窦前壁开窗时间，术中上颌窦黏膜穿孔率，术中患者主观感受及术后3天内患者反应，术后6个月进行上部结构修复时上颌窦及种植体骨结合情况。结果 ①实验组术中上颌窦前壁开窗耗时（7.34±0.72）min小于对照组（17.84±1.29）min，差异有统计学意义。②实验组上颌窦黏膜穿孔率为0，对照组上颌窦黏膜穿孔率为16.7%。③术中主观感受实验组患者较于对照组不适程度更加轻微。实验组术后3天内患者出现疼痛、肿胀程度轻于对照组。④所有病例在术后6个月行修复时均无上颌窦炎症，种植体稳固，骨吸收均小于1 mm。结论应用新型上颌窦提升工具进行上颌窦外提升术较普通球钻手术时间明显缩短，黏膜穿孔率低，患者术后反应轻，高效安全。

Abstract: Objective To assess the clinical efficacy of a new instrument in lateral window maxillary sinus lifting.Methods 34 patients with 51 posterior teeth lost were augmented with lateral window maxillary sinus lifting,22 patients using Dentium Advanced Sinus Kit as the experiment group and 12 patients using common ball drill as the control group.Then the sinus floor was elevated,filled with artificial bone,and the implant was inserted simultaneously,covered with biological membrane.The time of lateral window,the membrane perforation rate,patients′ subjective feeling during operation and the postoperative reaction three days after operation,as well as the situation of sinus and osseointegration of implant while finishing restoration in two groups were compared.Results ①The time of lateral window in the experiment group（(7.34±0.72) minutes) was less than that in the control group ((17.84±1.29) minutes).②The membrane perforation rate of the experiment group was 0,which was less than the control group (16.7%).③The painful and swelling feeling in the experiment group was slighter than that in the control group.4.All cases had no sinusitis and the bone resorption was less than 1mm.Conclusions The application of DSAK in lateral window maxillary sinus lifting could shorten the surgery time obviously with low membrane perforation rate and slighter postoperative reaction.It is safe ,quick and effective.
