Experimental and Numerical Evaluation of an Orthognathic Implant with Facial Asymmetry and Skeletal Class III

A numerical evaluation of an orthognathic prosthesis used in patients with facial asymmetry and mandibular prognathism was performed for this study. Mechanical testing was also performed by using axial tomography (computed tomography scan), and experimental methods such as photo-stress and image correlation were included. Our clinical case was a patient diagnosed with prominent mandible and abnormal size; atypical morphology, abnormal mastication and sense of smell, and difficulty talking as a consequence of the bone deformity; bad alignment of the mandible and upper maxilla, atypical movement of the tongue and deficiency for the occlusion process (closing of the mouth). This study aimed mainly to characterize the mechanical stress and structural behavior of numerical models obtained by the patient’s clinical and morphological profile through a computational approach based on the finite element method.
