Possibilities of the Manufacturing and?Simulation of the Load on a?Customised Mouthguard Used in Combat Sports

摘要

The?article presents an assessment of the state of stress and deformation of a?personalised tooth protector, taking into account various types of elastomer materials that allow optimal protection of the teeth in contact combat sports. The?load characteristics of the personalised protector, perfectly adhering to all, even clearly protruding from the anatomical line of teeth, were calculated using ANSYS 18 software. Numerical simulations of different elastomer materials were compared. Assessment of the state of stress and deformation of the protector allowed to demonstrate the legitimacy of protecting teeth with a?personalised tooth protector and to increase the safety of the teeth and soft tissues of the oral cavity in contact combat sports. Based on a?dental impression and plaster casting of the jaw made using an eviXscan 3D scanner, its model was digitalised. CAx techniques were used to design a?mouthguard. Furthermore, a?control code was generated and transmitted to a?CNC milling machine to make a?mouthguard fitted to the user’s teeth.
