摘要
目的探讨美学区单个上前牙即刻种植即刻非功能修复临床疗效。方法7例上颌单个无法保留患牙,拔除后即刻植入种植体,当日制作并戴入临时树脂冠,6个月后复诊取模,选择合适基台制作永久金属烤瓷或全瓷修复体,最终修复体戴入后1年复诊,比较刚戴入修复体与1年后随诊时种植体周骨组织水平以及红色美学指数(PES)的变化情况。结果种植体成功率为100%,种植体近、远中周牙槽骨变化分别为(0.79±0.48)mm、(0.71±0.46)mm;刚戴入修复体与1年后随诊时PES值分别为(8.6±1.3)和(11.1±1.8),Walcoxon统计学分析,两者差异有统计学意义(P=0.027)。结论在严格选择病例的情况下,单牙即刻种植即刻非功能修复,可取得很好的美学效果,种植体周软组织美学效果随着戴入时间增长可得到改善,是一种可行的方法。
Objective To observe the clinical effect of the restoration of a single upper missing tooth with immediate implant placement and non-functional prosthesis in the aesthetic area. Methods Seven consecutive patients with un-savable single teeth in the aesthetic zone were included. Teeth were extracted and replaced with immediate implant and non-functional provisional crowns. Suitable permanent abutments were chosen and porcelain-fused-metal or all-ceramic restorations were made on the abutments after 6 months. Patients were followed up 1 year after crown insertion. The marginal bone level around the implant and Pink Esthetic Score （PES） value immediately after crown insertion and 1 year later were measured for comparison. Results The success rate of implant was 100%, mesial and distal peri-implant bone changes were （0.79 ± 0.48）mm and （0.71 ± 0.46）ram respectively. The average PES value was （8.6 ± 1.3） and （11.1 ± 1.8）, respectively. Significant difference was found by Walcoxon analysis （P=0.027）. Conclusions For strictly selected cases, single-tooth immediate implant and immediate non-functional prosthetsis is an effective method. Good appearance can be achieved and the esthetics of peri-implant soft tissue can be improved over time.
