[摘 要]目的 研究拔牙位点保存技术对口腔种植患者美学效果的影响。方法 选取2021年3月-2023年3月于本院接受前牙口腔种植的96例患者为研究对象，以随机数字表法分为对照组(n=48)和观察组(n=48)。对照组应用常规口腔种植拔牙修复技术，观察组应用拔牙位点保存技术，比较两组牙槽骨高度、宽度与骨密度、牙龈乳头指数(PIS)、附着龈宽度、美学效果、种植体稳定系数(ISQ)、种植成功率及并发症发生情况。结果 观察组治疗后牙槽骨高度、宽度、骨密度高于对照组(P<0.05)；观察组治疗后PIS评分高于对照组，附着龈宽度大于对照组(P<0.05)；观察组治疗后美学效果评分高于对照组(P<0.05)；观察组ISQ评分、种植成功率均高于对照组(P<0.05)；观察组并发症发生率为2.08%，低于对照组的14.58%(P<0.05)。结论 拔牙位点保存技术对提高口腔种植患者美学效果具有积极影响，可减轻拔牙操作对牙槽骨高度、宽度及骨密度的影响，减少骨量丢失，有利于提高种植体稳定度及种植成功率，且患者满意度较高。

    [Abstract]Objective To study the effect of tooth extraction site preservation technology on the aesthetic effect of oral implantation patients. Methods From March 2021 to March 2023， 96 patients who received anterior dental implant in our hospital were selected as the research objects. They were divided into control group (n=48) and observation group (n=48) by random number table method. The control group was treated with conventional oral implant extraction repair technology ......
