摘　　要：目的:探讨前牙区即刻种植永久修复后的牙龈美学效果。方法:22例前牙缺失病例,行不翻瓣拔牙同期植入28颗种植体,上颌前牙24颗采用非埋入式种植术,下颌前牙4颗采用埋入式种植术,种植体愈合3～4个月进行永久修复。随访12～30个月(平均18个月)。根据Miller牙龈边缘组织退缩分类及Jemt牙龈乳头指数,分别观察种植体永久修复12个月后的牙龈边缘退缩及牙龈乳头状况;根据Albrektsson种植体成功标准,观察所植入的种植体状况。结果:28颗种植体留存率100%。Miller分类,18颗种植体牙龈边缘无退缩;8颗种植体牙龈边缘Ⅰ类退缩;2颗种植体牙龈边缘Ⅱ类退缩。种植修复体近远中Jemt牙龈乳头指数均为Ⅱ级以上。结论:前牙区即刻种植,延期修复是一项较成熟的手术方法,但须严格掌握适应证,才能获得良好的修复效果。Objective： To discuss the esthetic outcomes of immediate implant placements in anterior jaw region.Methods： 28 single-tooth implants（twenty-two patients） were included in the study.These implants placed immediately while ten fractured teeth and eighteen residual roots in the anterior region were extracted without flap reflection.24 nonsubmergible implants were placed in the maxilla and 4 submergible implants were placed in the mandible.Final prostheses were restored after 3 to 4 months.The follow-up time was from 12 to 30 months（mean： 18 months）.The marginal tissue recessions were analyzed according to Miller＇s classifications.The interproximal papillae were analyzed according to Jemt＇s classification.The stabilities of the implants were analyzed according to Albrektson＇s criteria of success.Results： The cumulative implant survival rates were 100% in these observation periods.No marginal tissue recessions were found in 18 implant sites.The marginal tissue recession index score at 1-level were found in 8 implant sites,the tissue recession index score of 2-level were in 2 implant sites.The mesial and distal papilla index score of 3-level were observed in 20 implant sites,the papilla index score of 2 in 8 implant sites.Conclusions： Immediate implant placement and delayed loading is a skilled technique.Strictly control of indications seem to be the key factor.
