For sports\u2010active person with malocclusion, specially designed mouthguard is often required.

The impact tests were carried out by a free\u2010falling object via testing machine and a vertical rod. The strains of the dentition with mouthguard were measured by means of strain gage system to compare between two different designs of mouthguard.
