RESUMEN
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.
