目的：通过对美学区单个上前牙种植修复临床疗效一年的回顾性研究，评估美学修复效果及影响因素。方法：20例上颌单个无法保留患牙，拔除后即刻植入种植体，6个月后复诊取模选择合适基台制作永久金属烤瓷修复体。永久修复体戴入后1年复诊，比较刚戴入修复体（基线）与1年后随诊时种植体周软组织健康状况以及红色美学指数PES的变化情况。结果：种植体成功率为100％。基线与1年后随诊时 PES 值分别为10.2±2.1和11.3±1.8。结论：在严格选择病例的情况下，单牙即刻种植可取得良好的美学效果，是一种可行的方法。%Objective: The purpose of this clinical study was to retrospectively evaluate the clinical effect of the restoration of a single upper missing tooth with immediate implant placement in the aesthetic area. Methods: 20 consecutive patients with un-savable single teeth in the aesthetic zone were included. Teeth were extracted and replaced with immediate implantation. Suitable permanent abutments were chosen and porcelain-fused-metal restorations were made on the abutments after 6 months. Patients were followed up 1 year after permanent restorations. The soft tissue health around the implant and Pink Esthetic Score(PES value)immediately after permanent restorations and 1 year later were measured for comparison. Results: The success rate of implant was 100%. The average PES value was 10.2 ±2.1 and 11.3 ±1.8 respectively. Conclusions: For strictly selected cases, single-tooth immediate implant is an effective method. Good appearance can be achieved and the esthetics of peri-implant soft tissue can be improved over time.
