Biomechanical analysis of titanium plate systems in mandibular condyle fractures: a systematized literature review

摘要

PURPOSE: To conduct a systematized review of the literature about the main methodologies used to evaluate the biomechanical fixation systems with titanium plates in fractures of the mandibular condyle. METHODS: A systematized review of literature was performed in the electronic databases PubMed, EMBASE, LILACS and MEDLINE without restriction of the publication date. The eligibility criteria were laboratory studies involving mandibular condyle fractures, studies using titanium plates, biomechanical studies, in vitro and computational studies involving the finite element method (FEM). RESULTS: Eleven articles that met the eligibility criteria were selected, including seven articles involving in vitro studies and four studies with biomechanical analysis by using FEM. CONCLUSION: Although few articles have used the finite element method, the results of in vitro studies were similar to those found in computational studies, regarding to the stable use of two titanium miniplates.
