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 allceramic 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)mm 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 nonfunctional prosthetsis is an effective method. Good appearance can be achieved and the esthetics of peri-implant soft tissue can be improved over time.
