| description |
The aim of this study was to observe the behaviour of different gingival endings of the restorations and their significance as support agents, with the addition or not of interradicular reinforcement in relation to the possible variants that may come from internal tensions of the teeth committed by a force. The approach that determined the line of research through photoelasticity allowed the visualization itself of the forces, for this purpose an experimental prototype was built which faithfully reproduced a restored dental piece exposed to forces of mastication. The different preparations under similar charges showed different internal grades of tension as indicated by the isochromatic orders, index of the different aptitude to transmit a positive effort according to the case. The preparations without shoulder and without post were the most favourable for presenting the minor concentration of internal tensions, greater uniformity of compression and traction lines and they also had the most favourable results in terms of stress gradient. |

Vitantonio, Eduardo Dentistry; Prosthodontics section tension; shaping; stress Odontología; Prostodoncia tallado, tensiones, shaping; stress The aim of this study was to observe the behaviour of different gingival endings of the restorations and their significance as support agents, with the addition or not of interradicular reinforcement in relation to the possible variants that may come from internal tensions of the teeth committed by a force. The approach that determined the line of research through photoelasticity allowed the visualization itself of the forces, for this purpose an experimental prototype was built which faithfully reproduced a restored dental piece exposed to forces of mastication.

El objetivo de este estudio fue observar el comportamiento de las distintas terminaciones gingivales de las restauraciones y su significado como agentes de soporte, con el agregado o no de refuerzo intrarradicular en relación a las posibles variantes que pueden originarse en las tensiones internas de las piezas dentarias comprometidas por una fuerza.El enfoque que determinó la línea investigativa a través de la fotoelasticidad permitió la visualización misma de las fuerzas, para ello se construyó un prototipo experimental que reprodujo con fidelidad una pieza dental con su restauración, expuesta a fuerzas de masticación.Las distintas preparaciones bajo estado de cargas similares mostraron diferentes gradientes internos de tensiones de acuerdo a lo indicado por los ordenes de isocromáticas, índice de la diferente capacidad de transmitir favorablemente los esfuerzos según el caso.Las preparaciones sin hombro y sin perno fueron las más favorables por presentar la menor concentración de tensiones internas, la mayor uniformidad en el trazado de las líneas de compresión y de tracción y, además tuvieron los resultados más favorables en cuanto al gradiente de tensiones.
