Abstract

Many athletes use mouth guard to protect their teeth, gums and soft tissues of cheek and mouth during the game as a protection but at the same time they feel problem to breathe improperly which leads to reduction in their stamina, this is because of the design error and improper ventilation space in it for the athletes. This study was conducted to highlight these problems and analyze the effect of air flow in the design of mouthguard. Three different designs of cavity model of air flow channel were analyzed by using computational fluid dynamic (CFD) approach. In this case, an ANSYS software was used to observe the air flow characteristic for ventilation purpose and determined the parameter related to it such as velocity, pressure and type of air inside and outside of the athlete’s mouth. The minimum and the maximum value of velocity profile and pressure has been obtained for further design consideration. The design, shape and number of channel on the mouthguard slightly influence the outcome result of analysis.
