GHEORGHE VOICU, GABRIEL ALEXANDRU CONSTANTIN, ALEXANDRU SARACIN SIMULATION OF MECHANICAL BEHAVIOUR IN MILLING AND POLISHING OF DENTAL POLYMERIC (RESIN) COMPOSITES Dental resin composites have a wide applicability in the dental field. They exhibit their own chemical composition that imparts certain physico-mechanical properties. The machining of the pieces of these composites must be sufficiently light, without affecting their strength. For processing these parts, respectively of the dental work, is used or carbide burs, or diamond burs, depending on the mechanical strength of the composite. To determine composite behaviour under action of the conical finishers was simulated their behaviour in specific simulation programs. As a result, stress concentrators may appear from the first processing which may affect the later resistance of the piece or dental work.
