| Outline of Final Research Achievements |
This study aimed to evaluate the effect of fiberglass reinforcement method in MG material for improvement toward high functionality of mouth guard (MG) which is the protective device against the orofacial injury.
The ethylene vinyl acetate copolymer was the most suitable MG material as base material for fiberglass reinforcement method among the commercial MG materials via evaluating the three points bending strength and the delamination strength between the base material and the reinforced material. It was suggested that the setting of buffering space for glass fiber reinforced MG was effective drastically via evaluating the shock absorption properties, which showed shock was attenuated effectively and the spread of impact became slow compared with a conventional base MG material.
Further investigation should be carried out to be satisfied the requirement for the fabrication of MG with clinical applications of fiberglass reinforced material.
