摘　　要：目的:观察上前牙区即刻种植即刻修复负载3年后软、硬组织的临床变化情况。方法:选择2008年10月至2012年10月期间就诊于北京大学口腔医院第二门诊部并拟在前牙区进行种植治疗的健康患者。观察即刻种植即刻修复及常规种植修复这两种方式的患者在修复即刻及3年后近远中牙龈乳头、唇侧龈缘水平高度以及种植体近远中侧骨水平的变化。结果:即刻种植组和常规种植组分别完成20例和24例,植入种植体分别为22颗和29颗。两组病例在永久修复时种植体稳定系数(implant stability quotient,ISQ)分别为76.32±3.20和76.93±3.36(P>0.05)。即刻种植组和常规种植组在修复3年后近中龈乳头高度变化分别为(0.34±0.54)mm和(0.05±0.39)mm(P=0.07),远中龈乳头高度变化分别为(0.43±0.42)mm和(0.36±0.48)mm(P=0.13),唇侧龈缘水平变化分别为(0.70±0.40)mm和(0.62±0.34)mm(P=0.23),种植体骨吸收量在近中侧分别为(1.02±0.50)mm和(0.88±0.46)mm(P=0.53),远中侧分别为(1.05±0.34)mm和(0.95±0.47)mm(P=0.21),两组间差异均无统计学意义(P>0.05),但在修复即刻,两组间牙龈乳头指数的分布情况不论是近中还是远中差异均有统计学意义(P<0.05)。结论:上前牙即刻种植即刻修复3年后的软、硬组织的变化与常规种植修复基本相当,但前者在缩短疗程、获得理想的种植体周围软组织形态方面要优于后者。Objective： To observe the change of soft and hard tissue in dental immediate implantation and immediate reconstruction in anterior region after loading 3 years. Methods： Patients with single anterior tooth loss in the Department of Second Dental Center,Peking University School and Hospital of Stomatology from October 2008 to October 2012 were enrolled. The gingival papilla height,labial gingival margin level and peri-implant bone level were measured immediately after the permanent restoration and 3 years later. Results： In the study,20 patients were treated by immediate implantation and immediate reconstruction for 22 implants; 24 patients were treated by delayed implant for 29 implants. Implant stability quotient（ISQ） value of the two groups showed no significant difference before permanent restoration（P〈0. 05）. In all the cases after loading 3 years,the average mesial gingival papilla height in implant area of the immediate group and delayed group changed by（0. 34 ± 0. 54） mm and（0. 05 ± 0. 39） mm respectively（P = 0. 07）,the distal gingival papilla height changed by（0. 43 ± 0. 42） mm and（0. 36 ±0. 48） mm respectively（P = 0. 13）,while the labial gingival margin level shrinkages were（0. 70 ±0. 40） mm and（0. 62 ± 0. 34） mm respectively（P = 0. 23）. Peri-implant bone losses in the mesial side were（1. 02 ± 0. 50） mm and（0. 88 ± 0. 46） mm respectively（P = 0. 53）,while those in the distal side were（1. 05 ± 0. 34） mm and（0. 95 ± 0. 47） mm respectively（P = 0. 21）. All these indicators showed no significant difference between the two groups（P〈0. 05）; When the permanent prostheses delivered,the distributions of the gingival papilla index were different between the two groups whether in the mesial side or in the distal side（P〈0. 05）. Conclusion： The changes of the soft and hard tissue of the immediate implantation and immediate reconstruction in anterior region after loading 3 years were basically equivalent to the convention
