Abstract
Para alcanzar resultados óptimos en la confección de prótesis completas se deben utilizar materiales con un comportamiento adecuado para asegurar buena oclusión y estética duradera. En este sentido son los dientes de resinas los materiales más utilizados. Se han desarrollado nuevos dientes fabricados con resinas reforzadas y composites nanohíbridos con la intención de ofrecer propiedades mejoradas respecto a otros tipos de dientes. El presente trabajo de investigación se trata de un ensayo clínico que pretende estudiar y comparar el comportamiento de prótesis completas realizadas con protocolos clínicos tradicionales confeccionadas con dientes de resinas acrílicas y con dientes de composite nanohíbrido. OBJETIVOS: El objetivo principal fue la determinación de las diferencias obtenidas entre ambos materiales teniendo en cuenta el desgaste y la estabilidad cromática de ambos tipos de dientes...
In order to achieve optimal results in the elaboration of complete dentures, suitably‐behaving materials must be used to ensure good occlusion and durable aesthetics. In this sense, resin is the material most used. New teeth made with reinforced resins and Nano Hybrid composites have been developed with the intention of offering improved properties with respect to other types of teeth. This research consists of a clinical trial that aims to study and compare the performance of complete dentures made following traditional clinical protocols and produced with SR Vivodent PE® acrylic resin teeth and with SR Phonares® Nano Hybrid composite teeth, both by Ivoclar Vivadent. OBJECTIVES: The main objective was to determine differences between the two materials, with regards to the wear and chromatic stability of both types of teeth. With regard to wear, vertical wear was compared at a macroscopic and microscopic level after six months of use by the same group of patients. For both types of materials statistically significant differences were looked for depending on the type of material, dental group, arch, quadrant and type of teeth. Chromatic stability was evaluated with a spectrophotometer on three front teeth at the 0 and 6 month periods in both types of teeth...
