RESUMEN
PURPOSE: This study was aimed to investigate the frequency of different classes of partial edentulism and the most frequently used design components of conventional removable partial dentures. MATERIALS AND METHODS: 63 patients who were treated with removable partial denture in Kyungpook National University hospital for 2003 - 2006 were selected. A total of 76 removable partial denture frameworks were investigated. Kennedy classification was used to identify the class of partial edentulism. RESULTS: Results indicated that Kennedy class I removable partial dentures were the most frequently constructed. Most patients'cases were designed without modification areas. CONCLUSION: The most common type of direct retainer were the RPI clasp and RPA clasp in both maxilla and mandible. Lingual bar, linguoplate and anterior posterior palatal straps were the more frequently used mandibular and maxillary major connectors respectively. We did not have any case about Kennedy class IV patients.
