摘要/Abstract

摘要： 目的： 研究上颌前牙拔除后即刻修复的临床效果。方法： 于2017年1月~12月开展本研究,并纳入此期间在我院行上颌前部单牙拔除和种植的150例患者。随机分为对照组和观察组。对照组给予常规拔牙、种植牙治疗。观察组给予拔牙后即刻种植牙治疗。术后当天、术后3个月、术后6个月,观察牙龈厚度、颈部骨吸收量、骨密度、种植体乳头指数分级,术后6个月实施红色美学指数(PES)评分、种植体边缘骨吸收(MBL)评分。结果： 术后3个月和术后6个月,两组牙龈厚度逐渐减小、颈部骨吸收量及骨密度均逐渐增加,与术后当天相比,P< 0.05。术后3个月,观察组颈部骨吸收量及骨密度均大于对照组,P< 0.05。术后6个月,观察组颈部骨吸收量及骨密度均大于对照组,牙龈厚度小于对照组,P< 0.05。在术后3个月和术后6个月,两组种植体乳头指数分级均呈逐渐降低趋势,且观察组种植体乳头指数分级优于对照组,P< 0.05。术后6个月,观察组PES评分和MBL评分均高于对照组,P< 0.05。结论： 上颌前牙拔除后立即给予种植牙修复的临床效果明显,术后恢复情况好,可提高美观性。

Abstract: Objective： To study the clinical effect of dental implant restoration immediately after maxillary ante- rior extraction. Methods： This study was conducted from January to December 2017 and included 150 pa- tients who underwent single-tooth extraction and implantation of the maxillary front in our hospital during this period. They were randomly divided into control group and observation group. The control group was given conventional tooth extraction and implant treatment. The observation group was given immediate dental implant treatment after tooth extraction. On the day after surgery, 3 months after surgery, and 6 months after surgery, gingival thickness, cervical bone resorption, bone density, and implant nipple index were graded. Red aesthetic index(PES) score and planting were performed 6 months after surgery. Body edge bone resorption(MBL) score. Results： At 3 months and 6 months after operation, the thickness of gin- giva decreased gradually, and the bone resorption and bone density of the neck increased gradually, com- pared with the day after surgery, P<0.05. At 3 months after operation, the bone resorption and bone miner- al density of the observation group were higher than those of the control group, P<0.05. At 6 months after operation, the bone resorption and bone mineral density of the observation group were higher than those of the control group, and the thickness of the gingiva was smaller than that of the control group, P<0.05. At 3 months and 6 months after operation, the nipple index of the two groups showed a gradual decrease, and the nipple index of the observation group was better than that of the control group, P<0.05. At 6 months af-ter operation, the PES score and MBL score of the observation group were higher than the control group, P <0.05. Conclusion： The clinical effect of the restoration of the implant after the extraction of the maxil- lary anterior teeth is obvious. The postoperative recovery is good and the appearance can be improved.
