I claim:
1. Process for the production of a dental guard suitable for sportsmen, comprising the following steps:
- (a) a dental impression tray having a biting area which has been approximately adapted to the upper or lower teeth, has at least one aperture in the biting area, and is made of thermoplastics material, is softened at a temperature in the range from 50° C. to 80° C., and is then individually adapted by light pressure to the upper or lower row of teeth and associated gum area to produce a dental guard, any surplus material is removed, and the individualised tray is hardened by cooling;
- (b) molding material is provided in said tray and it is again pressed onto the upper or the lower row of teeth;
- (c) the molding material is polymerised to form a soft buffer zone between the relatively hard materials of the tray and the teeth and to penetrate partially into and via said at least one aperture to form a soft buffer zone between the tray and the opposite row of teeth.
