拔牙位点保存技术在口腔种植临床的应用

Clinical application of extracted site preservation in dental implantation

目的:探讨拔牙位点保存技术在口腔种植临床中的应用方法。方法:将63例150颗种植体通过微创拔牙、即刻种植、引导骨再生方法植入拔牙位点,随访1年,观察种植效果。结果:1本组150颗种植体均符合种植成功标准;2拔牙位点的牙槽嵴高度降低约1 mm,颊舌向间宽度降低约2 mm;3软组织外形对称。结论:微创拔牙、即刻种植、引导骨再生3种方法交叉或结合使用,能达到拔牙位点的保存,是种植成功的重要保障。

PURPOSE：To introduce the method of extracted site preservation in dental implantation. METHODS：One hundred and fifty implants in 63 patients were placed by minimally invasive extraction, immediate implantation and guided bone regeneration for extracted site preservation. All the patients were followed-up for 1 year. RESULTS： （1）One hundred and fifty implants were placed successfully according to the criteria. （2）Alveolar ridge of extracted site preservation reduced 1 mm in height, buccal-lingual distance in alveolar ridge of extracted site reservation reduced 2 ram; （3）The shape of soft tissue was symmetrical. CONCLUSIONS： Minimally invasive extraction, immediate implantation and guided bone regeneration technique can be used to achieve extracted site preservation, which is the key to successful implantation.
