Research objective is to increase effectiveness of teeth protection by use of an individual protective dental splint which is produced by method of thermoforming of layers of copolymer of ethylene with vinyl acetate with the help of apparatus THERMOFORMER 2.1. Within the framework of the research a method was developed for production of a vector pattern which allows to transfer borders of the individual protective dental splint onto a blank in order to increase the quality of production of protective splint and to increase comport of its use. While modeling the pattern we used the vector graphics editor CorelDRAW. results of the research show that the maximum value of retention depends on pressure force during formation of the first layer of the splint. Borders of basis of an individual protective dental splint have a minimal effect on level of retention of the splint. This allows to adjust splint borders maximally and to make the cut from the side of palate up to base of alveolar bone of the upper jaw and incisive papilla at the front. Thereby the probability of vomiting reflex is lowered and adaptation time is reduced. Key words: THERMOFORMER 2.1, CorelDRAW, mouthguard, EVA.
