Design factors contributed to the fracture of removable partial dentures in the elderly

WANG Hai-ying (Department of Stomatology, General Hospital of PLA, Beijing 100853)  
Objective: To analyses the design factors contributed to the fracture of removable partial dentures in the elderly in order to improve the design level and the quality of the dentures. Methods: According to Wang Zhen-shou's classification the common patterns in the fracture of removable partial dentures were summed up by observing 216 clinical cases in the elderly, and the weakness locations and the design factors which caused fracture of removable partial dentures were analysed. Results: The fracture of mesiodistal direction was often occurred in the first type dentures when patients'occlusion was lower; the fracture of mesiodistal direction was occurred sometimes at the extension base of the second type dentures especially at the maxillary tuberosity and the mandibular retromolar pad when patients'occlusion was very lower; the palatine and lingual base plate of the third type and the fifth type dentures were broken frequently across with the dental arch at the location between two edentulous spaces especially nearing the edentulous spaces; the fourth type dentures were often suffered from the fall off of artificial teeth and the fracture of horizontal direction at the palatine base plate; the vertical fractures were easy to be seen at the palatine and lingual base plate of the sixth type dentures especially at the common boundary between the artificial teeth and the abutment teeth. There are some design and facture factors in all the fractures of removable partial dentures, and some proper measures against the fractures are also brought forward in this paper. Conclusions: It is important for improving the quality of the restoration with removable partial dentures that we must add more attention to the proper design and measures against the denture fractures.
