暂时修复体牙龈塑形对改善上颌前牙区种植义齿美学效果的临床研究

Clinical study on aesthetic effect of gingival shaping with temporary implant restoration in maxillary anterior teeth

目的:探讨上颌单颗前牙种植后采用暂时修复体进行牙龈塑形的美学效果。方法:随机选取80例上颌单颗前牙种植修复患者,根据是否进行牙龈塑形随机分为实验组和对照组,每组40例。实验组采取临时基台制作暂时修复体行牙龈塑形,对照组不进行临时冠牙龈塑形。修复完成后3个月、6个月、12个月,比较2组患者的种植体成功率、临床红色美学评分(pink esthetic score,PES)、影像学参数以及患者满意度。结果:两组患者的种植成功率均为100%。修复术后3个月,两组PES比较,差异无统计学意义;术后6个月、12个月,实验组的PES均高于对照组(P<0.05)。修复术后12个月,两组骨丢失量相比无统计学差异。修复完成后3个月、6个月、12个月,实验组患者满意度均高于对照组(P<0.05)。结论:美学区单颗前牙种植后采用暂时修复体进行牙龈塑形可以获得较好的软组织美学效果。

Objective:To explore the aesthetic effect of gingival shaping with temporary crown on single maxillary anterior teeth after implantation.Methods:Eighty patients with maxillary single anterior implant restoration were randomly divided into experimental group and control group,with 40 cases in each group.The experimental group was treated with temporary crownfor gingival shaping,while the control group without temporary crown.Follow-up examinations were conducted at 3,6 and 12 months after the restoration.The implant succ ess rate,the pink esthetic score(PES),radiographic parameter and patient satisfaction were compared between the two groups.Results:The success rate of implantation was 100%in both groups.Three months after the restoration,there was no significant difference in PES between the two groups.At 6 and 12 months after operation,PES in the experimental group was higher than thatin the control group(P<0.05).There was no significant difference in bone loss between the two groups at 12 months after the restoration.At 3,6 and 12 months after the restoration,the satisfaction of patients in the experimental group was higher than that in the control group,respectively(P<0.05).Conclusion:In the aesthetic area,better soft tissue aesthetic effect can be obtained by using temporary crown for gingival shaping after single anterior tooth implantation.
