Nivel de estr��s radicular en premolares superiores y presi��n ejercida en tejidos adyacentes: un modelo mec��nico en 3D

Abstract

RESUMEN Objetivo: Comparar el nivel de estr��s radicular y presi��n ejercida en tejidos adyacentes en premolares superiores 1.4 con efecto y sin efecto, f��rula a la compresi��n vertical y axial en pernos prefabricados; fibra de vidrio y titanio vs pernos colados de metal noble (Au) y metal colado n��quel cromo (NiCr), cementados con cemento resinoso autoacondicionante autoadhesivo mediante la t��cnica de elemento finito. Metodolog��a: Se realiz�� un estudio de tipo experimental y comparativo, con 8 modelos simulados en 3D de premolares superiores 1.4. Se utiliz�� el software FEMAP 11.1.2 para modelar el dise��o mec��nico en 3D. Resultados: El nivel estr��s radicular es mayor en los pernos prefabricados colados Au y NiCr tanto a 360 y 180�� en comparaci��n con los de fibra de vidrio y titanio; el promedio m��s representativo est�� en el NiCr a 360�� con 104.23 Mpa, y el m��s bajo en el Titanio 180�� con 83,79 Mpa. La presi��n ejercida en tejidos adyacentes en los premolares tiene mayor nivel en los pernos prefabricados a base de fibra de vidrio y titanio a 180�� en comparaci��n con los de metal noble y n��quel cromo, siendo el m��s representativo el de fibra de vidrio liso a 180�� con 1,43 y el m��s bajo el NiCr de 360�� con 1,30. Conclusi��n: El nivel estr��s radicular es mayor en los pernos prefabricados colados de Au y NiCr tanto a 360 y 180�� en comparaci��n con los de fibra de vidrio y titanio, y el nivel de presi��n ejercida en tejidos adyacentes en los premolares tiene mayor nivel en los pernos prefabricados a base de fibra de vidrio y titanio, ambos a 180��, en comparaci��n con los de Au y NiCr.
