    [摘 要]目的 探讨经牙槽嵴顶提升术在上颌后牙种植修复中的应用效果。方法 选取我院2019年1月-2021年1月收治的100例上颌后牙种植修复患者为研究对象，按照随机数字表法分为对照组和观察组，各50例。对照组采用侧壁开窗上颌窦底提升术联合同期种植，观察组采用经牙槽嵴顶提升术联合同期种植，比较两组手术指标、近远期疗效及疼痛程度。结果 两组上颌窦提升高度、种植体直径和种植体长度比较，差异无统计学意义(P>0.05)；观察组手术时间短于对照组，差异有统计学意义(P0.05)；观察组术后12、24个月种植体稳定性系数、剩余牙槽骨高度和平均获得骨高度均高于对照组，差异有统计学意义(P0.05). The operation time of the observation group was shorter than that of the control group， and the difference was statistically significant (P0.05). The implant stability coefficient， residual alveolar bone height and average bone height of the observation group were higher than those of the control group at 12 and 24 months after operation ......
