Median jaw tray, method of use and method of making digital complete denture

Abstract

The invention discloses a median jaw tray, a method of use and a method for making digital complete dentures, wherein the tray comprises an upper jaw tray, a lower jaw tray, an occlusal locating pin, an occlusal locator, and an external interface, and the bottom surface of the upper jaw tray is an occlusal tray. A flat plate, an occlusal locator is installed on the occlusal flat plate, and the mandibular tray is connected with the occlusal locator through an occlusal locating pin; the external interface is set at the front end of the maxillary tray, and the external interface is connected to the handle interface or the face bow interface; one end of the handle interface can be inserted into The external interface is fixed, the other end of the handle interface clamps the middle end of the facebow ruler, and the facebow ruler is parallel to the occlusal plane plate; one end of the facebow interface can be inserted into the external interface and fixed, and the other end of the facebow interface is provided with an insertable surface For the socket of the arch component, by using the tray provided by the present invention, the positional relationship and the occlusal plane of the upper and lower jaws can be accurately obtained, which simplifies the subsequent prosthesis manufacturing process while reducing the number of patient visits and makes the occlusal relationship of the final prosthesis more accurate.

Description

technical field [0001] The invention relates to the field of denture manufacturing devices, in particular to a median jaw tray, a use method and a manufacturing method applied to a digital complete denture. Background technique [0002] At present, with the aging of the population, the number of patients with edentulous and edentulous patients is also increasing. There are several methods to measure the patient's median position and occlusal plane to guide the arrangement of the restored artificial teeth: [0003] The traditional method is generally to formulate a joint based on the plaster model made by the doctor in the patient's mouth, place a wax embankment on the joint, and determine the relationship between the upper and lower jaws through the adjustment of the wax embankment in the mouth. This method is cumbersome and relies too much on the doctor's experience; [0004] Gothic jaw measurement is based on the plaster model made by the doctor and the preliminary vertic...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that it is too difficult and not accurate enough to measure the patient's centric jaw relationship and occlusal plane. The present invention provides a centric jaw tray, which can accurately obtain the upper and lower jaw positions when the patient visits the doctor for the first time relationship and occlusal plane, while reducing the number of follow-up visits for patients, it simplifies the subsequent restoration production process, making the occlusal relationship of the final restoration more accurate, and solving the defects caused by existing technologies
