Embodiment 1

[0035] A method for transferring occlusal relationship and shape design in dental occlusal reconstruction restoration, comprising the following steps:

[0036] a. Digitally scan the model, transfer the jaw position relationship determined by the occlusal pad restoration to the working model of the mechanical articulator, use the model scanner to scan the working model, convert the working model into a digital working model 1, and The occlusal relationship of the mechanical articulator is transferred to the digital virtual articulator;

[0037] b. Design the virtual aesthetic diagnosis wax-up, use CAD design software to design and complete the virtual aesthetic diagnosis wax-up on the digital working model 1, check the virtual aesthetic diagnosis wax-up to achieve mutual protection of occlusion, and combine the digital working model 1 and the virtual aesthetic diagnosis wax-up Save as two data;

Abstract

The invention discloses a method for transferring occlusal relationship and shape design in dental occlusal reconstruction and restoration, which belongs to the technical field of dental occlusal reconstruction and restoration, and is characterized in that it comprises the following steps: a. digital scanning model; b. designing virtual aesthetic diagnosis wax-up ; c, 3D printing aesthetic diagnosis wax-up; d, tooth preparation and digital scanning model taking; e, model fitting; f, complete the design and production of temporary restorations. The present invention overlaps and fits the working model of the completed tooth preparation and the virtual aesthetic diagnosis wax-up through two data fittings, transfers the jaw position relationship determined by the occlusal pad restoration to the temporary restoration, and can make the tissue surface and The abutment teeth after intraoral preparation fit closely, and there is no need for repeated relining and adjustment of the temporary restoration, which greatly improves the restoration efficiency and accuracy.

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...
