ABSTRACT:
A method of making a mouthguard by fabricating a relatively more rigid main body of a material, such as ethylene/vinyl acetate copolymer for example, and directly molding onto the troughs of the main body a liner which is of a relatively less rigid material, such as ethylene/vinyl acetate copolymer for example, that bonds directly to the material of the main body to form a mouthguard in which the trough liner is tooth-impressionable after having been so bonded. The mouthguard has a tri-laminar occlusal wall composed of the lower durometer liner sandwiching the higher durometer main body material, and the mouthguard exhibits surprising impact-absorbing characteristics that are helpful in protecting certain cranio-facial bone structure in response to certain impacts.
