Reinforcement of Unsupported Enamel by Restorative Materials and Dentin Bonding Agents: An In Vitro Study
OBJECTIVE Preservation of unsupported occlusal enamel after removal of underlying carious dentin may result in maintenance of aesthetics as well as wear resistance against the opposing enamel. This study investigates the influence of different restorative materials and bonding agents on reinforcement of unsupported enamel in molars and compares it with sound dentin. MATERIALS AND METHODS In t...

متن کاملComparative study of mechanical properties of dental restorative materials and dental hard tissues in compressive loads
There are two objectives. One is to show the differences in the mechanical properties of various dental restorative materials compared to those of enamel and dentin. The other is to ascertain which dental restorative materials are more suitable for clinical treatments. Amalgam, dental ceramic, gold alloy, dental resin, zirconia, and titanium alloy were processed as dental restorative material s...
متن کاملFriction and wear of restorative dental materials.
Many different instruments have been developed for the measurement of friction and wear.1-5 Often the instrument was designed to accommodate some particular type of material, environment, or test condition. Studies reported in the dental literature have been limited to wear measurements with simulated toothbrushing methods,6-9 or on prosthetic teeth mounted on an articulator.10 This study will ...
متن کاملCrackling noise in three-point bending of heterogeneous materials.
We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of convex polygons and cohesive elements are represented by beams. Computer simulations revealed that fracture proceeds in bursts whose size and waiti...
