摘　　要：目的:对前牙区牙槽嵴较狭窄病例采用微创技术和锥状种植体进行前牙区即刻加载修复并评价其远期临床疗效。方法:收集1998～2000年临床病例21例,应用非翻瓣式一期法环切术,将一段式锥状种植体植入前牙缺失区,57枚种植体分为即刻加载修复组(治疗组)27枚和常规延期修复组(对照组)30枚,术后观察指标为:GI、种植体周围炎、植体稳定性,拍摄X线片了解牙槽嵴吸收情况,随访10～12年,评价其远期临床效果。结果:治疗组和对照组的临床成功率分别为96.3﹪和96.7﹪,统计学无显著性差异。结论:小直径一段式种植体较适合国人前牙区牙槽嵴解剖结构,不易引起骨壁侧穿,初期稳定性好;非翻瓣式环切手术入路,可保留龈乳头的完整性,使患者免除二次手术痛苦。Objective：The alveolar ridge of anterior teeth for Chinese patient is relatively narrow.The bone tissue is not adequant for implant placement,which is main cause for implant lost.The purpose of this clinical study is to evaluate the efficacy of immediate loading of CDIC 1-stage screw-type implants in anterior teeth.Method：By using flapless surgery,the implant were placed in anterior missing teeth;57 implant were divided into two groups.In the test group（27 implants）,prostheses were using for the implants after surgery;In the control group（30 implants）,patients were given prostheses as usual.GI,peri-implantitis,implant stability and radiographic changes of ridge were recorded and assessed in 10～12 years follow-up.Result：The survival rates were 96.3 ﹪ and 96.7 ﹪ respectively for test group and control group;There is no significant difference in statistics.Conclusion：CDIC 1-stage screw-type implants is suitable for narrow alveolar ridge of anterion teeth in Chinese patients.It can prevent bone renetration and achieve good primary stability.Flapless surgery can keep intact of gingival and avoid second incision.
