上颌前牙单牙即刻种植术后即刻修复和延期修复的临床效果比较

摘要/Abstract

摘要： 目的比较上颌前牙单牙缺失即刻种植术后即刻修复与延期修复的临床效果。方法收集2015年1月至2017年9月在安徽省口腔医院种植中心完成修复的58例上颌前牙单牙种植病例，其中即刻种植即刻修复组29例（II组），即刻种植延期修复29例（ID组）。分别于患者永久修复时，修复后3个月、6个月、12个月，检测种植存留率，比较两组的红色美学评分（PES）、白色美学评分（WES）、种植体边缘骨吸收以及患者满意度。结果种植体存留率：两组种植体存留率皆为100%；边缘骨吸收：垂直骨吸收：3个月时远中位点骨吸收量即刻种植即刻修复组为（0.34±0.18）mm，即刻种植延期修复组为（0.45±0.13）mm，差异有统计学意义(P<0.05)，而永久修复3个月近中位点、6个月12个月近远中位点两组均无统计学差异(P>0.05)，水平骨吸收：永久修复12个月，MP1位点骨吸收量即刻种植即刻修复组（0.67±0.16）mm，即刻种植延期修复组（0.65±0.15）mm；MP2位点骨吸收量即刻种植即刻修复组（0.54±0.14）mm,即刻种植延期修复组（0.56±0.12）mm，MP1、MP2两个位点两组水平骨吸收量均无统计学差异； PES得分：即刻种植即刻修复组的PES总分在戴牙时，永久修复3个月、6个月、12个月得分分别为（9.69±1.04）、（10.00±1.03）、（10.59±1.20）、（10.79±0.98），均显著高于即刻种植延期修复组（P<0.05）；WES评分：即刻种植即刻修复组为（7.41±0.83），即刻种植延期修复组为（6.66±1.04），两组得分有统计学差异（P<0.05）；患者满意度：即刻种植即刻修复组患者满意度（9.12±0.28），即刻种植延期修复组为（8.89±0.35），两组得分有统计学差异（P<0.05）。结论即刻种植术后即刻修复与延期修复永久修复1年后在种植体存留率、边缘骨吸收方面无显著差异，但在美学效果方面优于即刻种植延期修复，患者满意度高。

Abstract: Objective To compare the clinical effects of single implant crowns in the anterior maxilla following immediate placement with immediate prosthesis or delayed prosthesis. Methods 58 patients within single implant crown in the anterior maxilla were included in the study. Among them, 28 patients received immediate implant placement and immediate prosthesis (II group), and 28 patients were given immediate placement and delayed prosthesis (ID group).The implant survival rate, pink esthetic score(PES), white esthetic score(WES), marginal bone resorption surrounding implants and patients satisfaction were compared between two groups 3 months,6 months and 12 months after final restoration. Results The implant survival rates of the two groups both reached 100%. The vertical bone resorption at distal sites at 3 months in II group was (0.34±0.18)mm, and in ID group was (0.45±0.13)mm, and the difference was statistically significant (P<0.05), but at 6 months and 12 months it showed no statistical difference between two groups. Horizontal bone resorption:At 12 months, the bone resorption at MP1 site in II group was (0.67±0.16) mm, (0.65±0.15) mm in ID group, at MP2 site in II group it was (0.54±0.14) mm, (0.56±0.12) mm in ID group, and there was no significant difference at MP1 and MP2 sites between the two groups. PES:The scores of PES at permanent restoration, 3 months, 6 months and 12 months were (9.69±1.04), (10.00±1.03), (10.59±1.20), (10.79±0.98), which were all significantly higher than those in ID group (P<0.05). WES and patients’ satisfaction at 12 months in II group were both higher than the other group, and there were statistical differences in them between the two groups. Conclusion There is no statistical difference in the marginal bone resorption of implants and implant survival rate between two groups, but in terms of aesthetic effect，immediate prosthesis is superior to delayed prosthesis, and patients satisfaction is also higher.
