A milling tooth splint is performed monolithically by getting an optical impression of the patient??s oral cavity clinical situation, by computer modelling of the tooth splint on the lingual surface of the splinting teeth with an opportunity to fix the tooth splint not less than 1 mm from the marginal gingiva. The tooth splint thickness is 2 mm. The production of the dental splint with a high accuracy of fit which is identical to the patient??s oral cavity clinical situation is the technical result of the technical result of the invention. Digital model helps to get optical impression of patient??s dentition and occlusial roller to compare them in modeling program. Modelling of the future tooth splint stars on digital model. The program models the tooth splint surface on the lingual surface of the splinting teeth automatically, following the contours of the teeth anatomical features. The constructions is fixed with the help of the composite cement of double rejection after being polished and fitted.
