【摘 要】目的 探究上颌窦外提升联合引导骨组织再生技术进行上颌后牙种植修复的临床效果。方法 选取2021年7月-2022年9月聊城市退役军人医院收治的60例上颌后牙区牙体缺失患者为研究对象，按照随机数字表法分为对照组与试验组，每组30例。对照组采用CBCT引导下单纯上颌窦外提升进行修复，试验组采用CBCT引导下上颌窦外提升联合引导骨组织再生技术进行修复，比较两组种植成功率、骨厚度、骨密度及修复后咀嚼情况。结果 试验组种植成功率、种植治疗3个月后骨密度、骨厚度、咀嚼效率均高于对照组（P<0.05）。结论 上颌后牙种植修复采用上颌窦提升联合引导骨组织再生技术治疗效果较好，能提高种植治疗成功率及植体植入区的骨密度和骨厚度，改善患者的咀嚼效率，值得临床应用。

【Abstract】Objective To investigate the clinical effect of maxillary sinus elevation combined with guided bone regeneration technique for maxillary posterior tooth implant restoration. Methods Sixty patients with missing teeth in the maxillary posterior region admitted to Liaocheng Veterans Hospital from July 2021 to September 2022 were selected as study subjects and divided into control group and experimental group according to the random number table method， with 30 patients in each group. The control group was restored by CBCT-guided external maxillary sinus elevation alone， and the experimental group was restored by CBCTguided external maxillary sinus elevation combined with guided bone regeneration technique. The success rate of implantation， bone thickness， bone density and chewing after repair were compared between the two groups. Results The success rate of implantation， bone mineral density， bone thickness and masticatory efficiency in the experimental group were higher than those in the control group （P<0.05）. Conclusion The maxillary posterior dental implant restoration treated with maxillary sinus elevation combined with guided bone regeneration technique is more effective， which can improve the success rate of implant treatment and the bone density and bone thickness of implant placement area， and improve the masticatory efficiency of patients， and is worthy of clinical application.

隨着种植修复的普及以及种植区软硬组织增量技术的广泛应用，临床中越来越多牙列缺损病例能够通过种植修复实现治疗[1]。在此区域进行种植修复可能会出现因骨量不足导致的种植失败或造成上颌窦穿孔、炎症浸润等情况发生[2]，因此采用上颌窦提升技术进行骨增量是十分必要的[3]。上颌窦外提升技术（maxillary sinus elevation）指通过开窗等方式在直视上颌窦窦腔情况下于上颌窦黏膜下植入骨替代材料以解决上颌窦与上颌牙槽嵴之间垂直骨量不足情况，目前主要应用于垂直骨高度不足5 mm的患者[4]。引导骨组织再生技术（guided bone regeneration）指将骨替代材料植入骨缺损区，并覆盖屏障膜以保护骨替代材料，从而实现缺损区的骨增量[5]。上颌窦提升技术进行骨增量可以为植体植入提供更加稳定的环境，同时可避免上颌窦穿孔等相关并发症的发生。……
