TRENTO, Guilherme dos Santos et al. Assessment of masticatory forces in a mandibular reconstruction titanium plate through finite element analysis. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2016, vol.16, n.1, pp. 13-17. ISSN 1808-5210.

Surgical ressection is a radical treatment of some pathologies that affect the mandible and its structures. The technique is based on total removal of the lesion with a safe margin in all extension of the bone. Partial mandible resection results in a difficult to obtain the aesthetic and functionality of the stomatognathic system. In such cases, is recommended a titanium plate commonly used to mandibular reconstruction. Finite Element Analysis (FEA) is a form of math analysis which is based on division of a structure in a finite number of small areas. In general, FEA has the ability to mathematically model structures making possible applying forces in any point and/ or direction. Thereby, it can bring forth datas of displacement and tension being possible representing in vivo situation. This study aims to analyze and simulate the tensions generated by the masticatory forces, using FEA in a mandibular reconstruction with titanium plate after partial resection.
