[摘要]目的:探讨一段式细颈种植体用于缺牙间隙偏小的单牙种植修复技术的适应证、操作技巧,评价其临床疗效。方法:使用HBIC一段式种植体植入25例牙缺失患者,共植入32枚种植体。采用非翻瓣(Flapless)一期法种植,不做临时冠修复,待愈合3个月后直接行粘结永久烤瓷冠修复。经检测种植体动度、牙龈出血指数(gingival bleeding index,GI)及有无种植体周围炎、X线根尖片等指标,评价临床成功率。结果:随访1～4年,仅1例患者的2枚种植体松动、脱落,其余种植体均获成功,临床成功率为93%。结论:一段式细颈种植体用于小间隙单牙缺失种植修复要达到精良、美观的修复效果,其成功的关键取决于对适应证的把握,以及良好的手术和修复技术。

Abstract:ObjectiveSingle dental implant prosthesis of small edentulous space by one-stage narrow-neck implant is a secure simple prosthesis.The report discussed the indication operating technique and the clinical effects of the prosthesis.Methods25 patients age range from 20 to 55 years old (mean age: 38 years),were planted HBIC one-stage implant,including 32 implants.Tell patients not to morsus food with the teeth of implantation region and maintain oral hygiene,to attend the clinic on time,three months after healing, implants were restored bypermanent porcelain complete veneer crown.Primary stability,gingival bleeding index(GI),peri-implantities.apex radicis dentis X-rays films were analysed to determine the clinical results.ResultsAfter 1～4 year follow-up,2 implants in 1 case were lost.The clinical successful rate was 93%.ConclusionSingle dental implant prosthesis of small edentulous space by one-stage narrow-neck implant,want to come up to excellent, beautiful repaired result,the key is the certainty of indication and good operating technique.

近年来,种植义齿以其小巧、舒适、美观,不损伤健康邻牙而受到患者青睐,对于缺牙间隙偏小不能植入常规标准直径(3.75～4.3mm)根形种植体的缺牙修复,其种植修复方法和远期疗效一直是学者较为关注的问题。本组病例均采用国产细颈一段式牙种植体用于小间隙单牙缺失的美学修复,经临床使用观察1～4年,在功能和美观上达到理想效果,现就本组病例的适应证选择、操作方法及临床效果进行探讨与总结。
1资料和方法
1.1临床资料:本组25例(男9例,女16例)牙缺失患者,共植入32枚种植体,年龄20～55岁,平均38岁。种植牙位:上颌第一前磨牙9枚,上颌侧切牙12枚,下颌前磨牙3枚,下颌前牙8枚。适应证选择:种植区要有充分可用骨量,要求缺牙间隙近远中距离在5.8～7mm,牙槽骨颊舌向厚度不小于6mm,牙槽骨属于Lekholm和Zarb分类的Ⅰ～III级骨质和健康的软组织覆盖为宜。
1.2材料:使用国产HBIC(河北医科大学厚朴口腔种植科技中心生产)一段式细颈种植体,种植体的植入体、颈部、基台为一整体 ......
