摘　　要：背景:圆锥形套筒冠义齿具有能够自行摘戴、清洁方便、固定义齿异物感小、功能恢复良好等优点,所以近年来应用广泛,但随之也出现了一些问题。目的:综述分析圆锥形套筒冠义齿修复的常见问题并提出对策。方法:应用计算机检索1980至2013年中国知网及PubMed数据库,中文检索词为"圆锥形套筒冠,基牙,临床观察",英文检索词为"Cone sleeve crown,abutment,Clinical observation",并且利用主题词补充扩展,广泛查阅近年来有关套筒冠的文献,限定文献语言为英语及中文。结果与结论:圆锥形套筒冠义齿作为修复牙周病伴发牙列缺损的较为理想修复方式,总体来说效果良好,但维持长期稳定的临床效果是套筒冠修复技术面临的主要难题。近年来学者也通过多种方法提高其长期稳定性,例如改变内冠材料效果最为突出,但这些方法在实际临床应用中的远期效果还需要长期观察。圆锥形套筒冠义齿修复后出现的基牙折裂、内冠脱落、基托折裂、牙周问题、固位力降低等为常见症状,通过修理一般不影响套筒冠义齿的继续使用。BACKGROUND：Telescopic crown-retained removable partial dentures are characterized as pick to wear voluntarily, convenient to clean, smal foreign body sensation of the fixed denture, and good functional recovery, and have been widely used in recent years. However, there are also some problems existing. OBJECTIVE：To review the common problems of the telescopic crown-retained removable partial dentures and to raise the countermeasures. METHODS： A computer-based search of CNKI and PubMed （1980-2013） was performed for relevant articles addressing the telescopic crown using the keywords of “cone sleeve crown, abutment, clinical observation” in Chinese and English, respectively. RESULTS AND CONCLUSION：Telescopic crown-retained removable partial dentures are an ideal method for repair of dentition defects associated with periodontal disease. In summary, the telescopic crown-retained removable partial dentures have good clinical effects, but how to maintain the long-term stability is the main chalenge. In recent years, a variety of ways have been developed to improve the long-term stability, such as changing the inner crown material, which obtains the most prominent achievements, but these methods need to be further observed in clinical applications. Common complications for telescopic crown-retained removable partial dentures include abutment fracture, inner crown shedding, denture fracture, periodontal problems, and reduced retention force, which generaly cannot influence the application of telescopic crown-retained removable partial dentures through repair.
