摘　　要：目的:对比传统法临时冠和镜像翻转法临时冠在前牙种植软组织塑形方面的效果,为提升前牙种植美学效果提供参考。方法:选取2022年1月~2022年12月就诊于河北医科大学口腔医院修复科行单颗前牙种植病例50例,二期手术时按照随机原则分为传统组(n=25)采用传统技术制作临时冠并行软组织塑形,镜像组(n=25)采用镜像翻转+CAM打印临时冠。对比即刻修复时与1个月临时冠塑形后美学修复效果与软组织形态。结果:镜像翻转+CAM在临时冠塑形修复后的美学效果优于传统法,修复后1个月镜像组近、远中牙龈乳头高度相比即刻修复明显增加(P<0.05),传统组未见明显改变(P>0.05);且红色美学评分(pink esthetic score,PES)高于传统组。结论:镜像翻转+CAM复制并模拟天然牙的颈部穿龈形态,可以控制穿龈袖口形状和维持软硬组织的形态,获得可预期的美观效果和牙周健康,同时简化现有制作步骤,缩短疗程,为前牙种植修复的软组织塑形重建和维持提供一定的临床参考。Objective:To compare the effect of traditional method and mirror inversion method in soft tissue shaping of anterior dental implant,and to provide reference for improving the aesthetic effect of anterior dental implant.Methods:From January 2022 to December 2022,50 patients who underwent single anterior tooth implantation in the Department of Prosthodontics,Hospital of Stomatology,Hebei Medical University were selected.According to the random principle,they were divided into traditional group(n=25,used the temporary crowns)and the mirror group(n=25,used the technique of Mirror flip+CAM)to print temporary crowns.The aesthetic effect and soft tissue morphology were compared between the immediate restoration and 1 month after the temporary crown shaping.Results:The aesthetic effect of the mirror-flipped+CAM method after temporary crown molding restoration was better than that of the traditional method.The height of the proximal and distal gingival papilla in mirror group increased significantly at 1 month after restoration(P<0.05),but no significant change was found in traditional group(P>0.05).The pink esthetic score(PES)was higher than the traditional method.Conclusion:Mirror-flip+CAM can replicate and simulate the shape of the neck cupping of natural teeth by controlling the shape of the cupping cuff and maintaining the morphology of soft and hard tissues,so as to obtain predictable aesthetic effect and periodontal health.At the same time,it can simplify the existing manufacturing steps and shorten the treatment time,and provide certain clinical reference for the soft tissue remodeling and maintenance of implant restoration in anterior teeth.
