Mounting method for false tooth biting test

Abstract

The invention discloses a mounting method for false tooth biting test. The method specifically comprises the following steps: a, producing tooth models; b, producing tooth model bases; c, producing abiting cushion board, namely, c1, producing an upper bearing plate and a lower bearing plate, and correspondingly mounting the upper bearing plate and the lower bearing plate onto an upper jaw plate and a lower jaw plate of a biting rack; c2, preparing gypsum, arranging a lower gypsum layer between the upper bearing plate and the lower tooth model base, and making one side, close to the upper jawplate, of the lower tooth model base in the vertical center of the biting rack; c, biting and positioning the upper tooth model and the lower toot model after the lower gypsum layer is dried; c4, rotating the upper jaw plate until a top column on the upper jaw plate is propped against a jaw plate; calculating the distance between the upper tooth model and the upper jaw plate; c, arranging an uppergypsum layer between the upper bearing plate and the upper tooth model base; c6, arranging a balancing weight on the upper side of the upper jaw plate; d, modulating, namely, reducing the expansion of the gypsum in the vertical direction during mounting for biting test, and thus the biting test accuracy is high.

Description

technical field [0001] The invention relates to an installation method for denture occlusal experiments. Background technique [0002] Dentures are artificial teeth that replace missing natural teeth, also known as dentures. Severe periodontal disease, dental caries and trauma can cause partial or even complete loss of dentition. Tooth loss can affect the face, pronunciation, and chewing functions, and increase the burden on the stomach. If it is not repaired in time, the adjacent teeth will tilt and shift, and the opposing teeth will elongate, causing occlusal disorder. Partial loss of dentition can be repaired with fixed dentures or removable dentures, or with complete dentures (total dentures) when there are no teeth. [0003] In the process of denture restoration, the dental model is firstly designed according to the specific conditions of the patient, then the dental model is installed on the articulator for occlusal experiments, the dental model is tested, and the to...

Problems solved by technology

[0005] In the prior art, when the dental mold is made, the upper dental mold and the lower dental mold will be respectively fixed on the upper jaw plate and the lower jaw plate. During the fixing process, since the upper and lower dental molds are not directly fixed on the upper and lower jaw plates Can be in good contact, so when installing the upper and lower dental models, place plaster between the upper dental model and the upper jaw plate, the lower dental model and the lower jaw plate, until the upper dental model and the lower dental model can be occluded So far, in the actual operation process, the upper and lower dental models are separated, and the gypsum layer will expand during the solidification process, thereby changing the thickness of the gypsum layer and changing the distance between the upper and lower dental models, making the occlusal test inaccurate
