Abstract

A mouthguard is a protective device that covers the teeth, gums and soft tissues of cheek and mouth. The mouthguard functioning as a buffer from trauma and provide level of protection based on the type of protection while playing sports. However, many athletes choose not to use the mouth guard during playing sports. This is because athletes facing the difficulty in breathing properly due to poor ventilation space at the mouthguard and current design are uncomfortable. It thus reduces their stamina. This study was conducted by analysis existing design of mouthguards. In this study, three designs of mouthguard with same type are selected and each of them have different number, shape and design of air flow holes. These existing mouthguards will be analyzed by using computational fluid dynamic (CFD) approach. Ansys CFX is one of the software fully integrated in the Ansys Workbench 15.0 platform and also CFD analysis tool. The Ansys CFX software was used to analyze the existing mouthguard and to obtain the required air flow characteristic. The objective of this research was to determine the parameter related such as velocity, pressure and type of air form inside the athlete’s mouth. Overall, it can be concluded that the minimum and the maximum value for velocity profile and pressure has been obtained, at the same time the type of air form has been observed at the end of this research.
