520			_aTemporomandibular Joint (TMJ) is one of the most critical parts of the human body that connects the human jaw to the skull. The muscles connecting and supporting the joint are one of the most frequently used elements of the body. The functionality of these muscles and thereby, the joint gets disturbed due to multiple underlying conditions resulting in various ailments. One such major ailment is the Trismus or Lockjaw, where the muscles get heavily stressed such that the patient is unable to have adequate mouth opening. The condition necessitates surgical treatments followed by external intro-op measures to rehabilitate the functioning of jaws. The present thesis work aims to develop a rehabilitation device that allows controlled mouth opening by following a clinically correct trajectory, provides comfort during the exercise, and serves ergonomic and aesthetic aspects. A conceptual linkage is derived from the basic four-bar mechanism to trace the human jaw trajectory using an optimization algorithm. The algorithm considers either the analytical equation of desired jaw trajectory or point datasets to derive desired linkage dimensions such that the error between the desired and actual path is minimized.The algorithm is implemented using MATLAB® and Genetic Algorithm (GA) toolbox. The linkage dimensions are further transformed into the functional mechanism by selecting appropriate structural elements. The aesthetic and ergonomic aspects of the functional mechanism are achieved subsequently using the computational tool, Creo Parametric®. It is desirable to have a lightweight design for effective usage by clinical professionals and patients. A preliminary design analysis has been carried out for weight reduction by using a topology optimization tool using ANSYS®. The proposed design has good potential for commercialization as it offers multiple advantages in comparison to alternate options in the market.Keywords Temporomandibular Joint (TMJ); Trismus; Jaw rehabilitation; four-bar mechanism; Genetic Algorithm; Topology optimization; Product design and Development
