Comportamiento biomecánico de prótesis híbridas implanto soportadas en el maxilar inferior en función de las características geométricas de la subestructura: Estudio de caso de un paciente totalmente edéntulo con pérdida ósea severa

Abstract

Hybrid implant-supported prostheses are used for totally edentulous patients, in 0.17% of the population. The failure of this type of prosthesis is related to mechanical failures due to occlusal overload and a geometry of the substructure that does not allow an adequate distribution of stresses on the prosthesis, the bone and the implants, specifically in patients with severe bone loss. For this reason, it is important to determine the biomechanical behavior of an implant-supported hybrid prosthesis in the lower jaw based on the geometric characteristics of the substructure for a totally edentulous patient with severe bone loss, by planning the clinical case for the personalized design of the substructure of the substructure. implant-supported hybrid prosthesis in order to establish the geometric characteristics and the material for the design of the substructure of the prosthesis considering the anatomical conditions of the patient and in this way numerically determine the state of stresses and deformations by means of computational simulation of the implant-bone interface according to the conditions established for the design of the hybrid prosthesis.
