单颗上颌前牙即刻种植与即刻修复的临床和美学效果

目的 研究单颗上颌前牙即刻种植即刻修复和延期种植修复的临床疗效和美学效果差异。 方法 将60例需要进行单颗上颌前牙种植修复的患者随机分为即刻种植组（n=30）和延期种植组（n=30），分别比较即刻种植组和延期种植组的3年种植成功率、术后3年后种植体骨质吸收情况和红色美学指数（PES）白色美学指数（WES）评分。 结果 即刻种植组和延期种植组的植成功率和术后3年种植体骨质吸收差异没有统计学意义（P>0.05）；即刻种植组PES评分和WES评分均高于延期种植组，差异有统计学意义（P<0.05）。 结论 即刻种植即刻修复和常规的延期种植修复相比，能明显的提高修复的美学效果，并且种植的成功率和种植体周围骨组织吸收并没有明显差异，具备一定的临床推广价值。  

Clinical and aesthetic effect of immediate implantation and immediate prosthesis on a single maxillary anterior tooth

Objective To explore the clinical and aesthetic effect of immediate implant immediate prosthesis and delayed implant delayed prosthesis on single maxillary anterior teeth. Methods Sixty cases who need for single maxillary anterior dental implants were randomly divided into immediate implantation group (n=30) and delayed implant group (n=30). The 3 years implant success rate, postoperative 3 years after implant bone absorption and Pink Esthetic Score (PES) and White Esthetic Score (WES) were compared. Results The differences of graft success rate and postoperative 3 years after implant bone resorption in 2 group were not significant (P>0.05). PES and WES score in immediate implantation group were higher than that of delayed implant group (P<0.05). Conclusion Compared to conventional repair, immediate implant and restoration can improve the aesthetic effective. The success rate of planting and the bone resorption around implants have no significant difference. It has a certain clinical value.
