In this study, a 3D finite element model of an intact mandible was used for the simulation of the movement of the lower jaw and analysis of the effects of TemporoMandibular Joint (TMJ) prosthesis replacement on the jaw movement. Seven bundles of muscle fibers were inserted in their appropriate positions following anatomical data. | Analysis of temporomandibular joint prosthesis using finite element method and a patient specific design Engineering Solid Mechanics 7 2019 83-92 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Analysis of temporomandibular joint prosthesis using finite element method and a patient specific design Alireza Omidia Christophe Jeanninb Mohammad Ali Nazaria and Masoud Shariat Panahia a Department of Mechanical Engineering University of Tehran Tehran Iran b Faculty of Odontology Claude Bernard Lyon University Lyon France A R T I C L EI N F O ABSTRACT Article history In this study a 3D finite element model of an intact mandible was used for the simulation of the Received 10 July 2018 movement of the lower jaw and analysis of the effects of TemporoMandibular Joint TMJ Accepted 8 October 2018 prosthesis replacement on the jaw movement. Seven bundles of muscle fibers were inserted in their Available online appropriate positions following anatomical data. Digastric geniohyoid and lateral pterygoid 8 October 2018 Keywords muscles were considered for opening the mouth while medial pterygoid superficial masseter deep Temporomandibular Joint masseter and temporalis muscles were used for closing the mouth. Then the TMJ was replaced by TMJ two different types of TMJ prostheses in the same way as in a surgery operation. One of the FEM prostheses was designed based on anatomical shape of the ramus and condyle of the mandible TMJ prosthesis while the other one was taken similar to the commercial TMJ prostheses. Eventually all three Muscle Mechanics models underwent an opening jaw simulation and produced an identical range of motion while were mismatched in other parameters. The results show that since the anatomical TMJ prosthesis resembles the shape and structure of an intact mandible therefore it is more capable of simulating the motion of mandible compared to the commercial TMJ prosthesis.
