Objetivo: Mejorar la comprensión de los cambios generados por los procedimientos restaurativos a través de modelos fotoelásticos. La reconstrucción dental debe fundamentarse en principios de oclusión para no provocar puntos prematuros de contacto durante los procedimientso de preparación y restauración que pueden provocar transtornos como el trauma oclusal, disfuncion de la ATM, o fracturas. En este documento se presenta un metodo didactico para visualizar de forma objetiva las cargas oclusales y su distribución. Materiales y métodos: Se realizaron modelos fotoelasticos de dientes y segmentos maxilares, para visualizar los efectos de las preparaciones dentales y restauraciones, asi como el desgaste de puntos prematuros de contacto. Resultados: Por fotoelasticidad se analizó la dirección, intensidad y distribución de esfuerzos en la corona y soporte óseo. Conclusiones: La tecnica permite visualizar cómo se afectan las estructuras desde la preparación cavitaria, los diferentes esfuerzos con fresas de diamante o carburo, además de observar cómo un punto prematuro de contacto no solo afecta al órgano que lo contiene sino a estructuras aledañas.
Objective: To improve the understanding of the changes generated by restorative procedures through photoelastic models. Dental reconstruction should be based on principles of occlusion in order not to cause premature contact points during preparation and restoration procedures that can lead to disorders such as occlusal trauma, TMJ dysfunction, or fractures. This paper presents a didactic method to objectively visualize occlusal loads and their distribution. Materials and methods: Photoelastic models of teeth and maxillary segments were made to visualize the effects of dental preparations and restorations, as well as the wear of premature contact points. Results: The direction, intensity and distribution of stresses in the crown and bone support were analyzed by photoelasticity. Conclusions: The technique allows us to visualize how the structures are affected from the cavity preparation, the different stresses with diamond or carbide burs, in addition to observing how a premature contact point not only affects the organ that contains it but also the surrounding structures.
