[摘 要]目的 探讨后牙牙列缺损患者采用改良粘接固位种植义齿修复术的临床效果。方法 选取2020年6月-2021年12月优德口腔门诊部收治的80例后牙牙列缺损患者，以随机数字表法分成观察组(40例)与对照组(40例)。对照组给予常规粘接固位修复，观察组给予改良粘接固位种植义齿修复治疗，比较两组修复效果、咀嚼功能、牙周相关指标[牙菌斑指数(PLI)、龈沟出血指数(SBI)]、并发症发生情况。结果 观察组近中、远中牙槽骨高度、宽度大于对照组，骨吸收量低于对照组(P<0.05)；两组术后咬合力大于术前，且观察组大于对照组(P<0.05)；两组术后PLI、SBI低于术前，且观察组低于对照组(P<0.05)；观察组并发症发生率为5.00%，低于对照组的22.50%(P<0.05)。结论 针对后牙牙列缺损患者给予改良粘接固位种植义齿修复治疗能够提高修复效果，促进咬合功能恢复正常，改善出血情况，降低牙菌斑形成，减少并发症发生几率。
