上颌单前牙即刻种植修复和延期种植修复的美学效果比较

目的:比较上颌单前牙即刻种植即刻修复和延期种植延期修复的美学效果。方法:收集42例上颌单前牙种植修复病例,A组行即刻种植即刻修复(20例),B组行延期种植延期修复(22例)。采集永久修复后6个月复查的口内数码照片,用红白美学指数对其评分。统计分析以比较2组病例得分有无差异。结果:A组的种植体留存率(95.0%)和B组的种植体留存率(100%)相当,差别无统计学意义。A组红色美学指数(PES)得分(12.05±0.97)和白色美学指数(WES)得分(8.00±1.41)均高于B组PES(10.50±1.57),WES(6.95±1.21),差别具有统计学意义。A组PES≥12的病例所占比例(68.4%)高于B组(22.7%),差别具有统计学意义。结论:即刻种植即刻修复组的短期美学效果较延期种植延期修复组更好,且两者的种植体留存率没有显著差别。

Esthetic Outcome of Single Implant Crowns following Immediate Implant Treatment and Delayed Implant Treatment in the Anterior Maxillary.

Objective: To compare the esthectic outcome of single implant crowns following immediate implant treatment (IIT) and delayed implant treatment (DIT) in the anterior maxillary. Methods: Forty-two dental implants were included in the study, 20 implants received immediate implant treatment and 22 implants received delayed implant treatment. Intra-oral digital photographs were obtained 6 months after final restoration. Pink esthetic score (PES) and white esthetic score (WES) were calculated. Statistical analysis was performed to compare the parameters between two groups. Results: The implant survival of IIT was 95.0% and that of DIT was 100%. There was no significant difference between two groups. Mean values of PES were 12.05±0.97 for IIT and 10.50±1.57 for DIT. Mean values of WES were 8.00±1.41 for IIT and 6.95±1.21 for DIT. Significant differences were found between the two groups in PES and WES. 68.4% of the IIT group showed perfect pink esthetic outcome (PES≥12), but only 22.7% in the DIT group. These values showed statistically significant differences. Conclusion: The IIT group showed a better pink and white esthetic outcome than the DIT group in a short observing period, and they can get comparable implant survival.
