Abstract
Mechanical behaviour of removable partial dentures is a priority among experimental papers, in order to define the fracture mechanism of acrylic resins. Present paper presents experimental results concerning mechanical behaviour of two different dental acrylic resins, respectively Meliodent and Royaldent. There are determined mechanical characteristics on Zwick Roell Equipment with testXpert system. The fracture samples were examined on stereomicroscope Olympus. The difference in mechanical behaviour is explained in terms of stereomicorscopic analysis. Keywords: dental resins, removable partial denture, stereomicroscopy, fiber, composite material
