Abstract

The invention discloses a method for transferring occlusion relationship and form design in dental occlusion reconstruction and restoration, belonging to the technical field of dental occlusion reconstruction and restoration. The method is characterized by comprising the following steps of: a, digitally scanning a model; b, designing a virtual aesthetic diagnosis wax pattern; c, performing 3D printing on the aesthetic diagnosis wax pattern; d, conducting tooth preparation and carrying out digital scanning for formulation of models; e, performing model fitting; and f, completing the design andmanufacturing of a temporary restoration body. According to the invention, data fitting is carried out twice, a working model completing tooth preparation is overlapped and fitted with the virtual aesthetic diagnosis wax pattern, and the jaw position relationship determined by an occlusal pad type restoration body is transferred to the temporary restoration body, so a tissue surface can be tightlyattached to butments after intraoral preparation, repeated relining, adjustment and modification of the temporary restoration body are not needed, and restoration efficiency and restoration precisionare greatly improved.

Description

technical field [0001] The invention relates to the technical field of dental occlusal reconstruction and restoration, in particular to a method for transferring occlusal relationship and shape design in dental occlusal reconstruction and restoration. Background technique [0002] Severe tooth wear often destroys the shape of the tooth body and shortens the clinical crown, which in turn leads to a decrease in the vertical distance and shortening of the lower 1 / 3 of the face, which seriously affects the masticatory function and even leads to temporomandibular joint disorders. Using fixed occlusal reconstruction technology to restore severely worn teeth with dentition defects, including making occlusal pad restorations to change the patient's occlusal vertical distance, making aesthetics on the jaw position determined by occlusal pad restorations Diagnose the wax-up, transfer the occlusal relationship and shape design of the aesthetic diagnosis wax-up to the temporary restorat...
