Proper selection of the mouthguard design can result in better breathing and speech performance during sports activities. This study emphasizes the design of air flow channels on mouthguard, which is very scarce to be found in literature so far. Air flow simulations based on actual design of mouth mould wearing a mouthguard using computerised fluid dynamics (CFD) simulation are carried out. Modelling and simulation analysis are conducted through various air flow channel designs utilizing a stock mouthguard as a benchmark. The selection criterion was based from previous dental studies which emphasized on the good effect of high exhale flow rate and low exhale pressure when designing the mouthguard’s air flow channel. Based from the current simulation results, it is apparent that the developed model satisfied those criterions and might be proposed for fabrication.
