Middle jaw tray, using method and manufacturing method applied to digital complete denture

Abstract

The invention discloses a middle jaw tray, a using method and a manufacturing method applied to digital complete dentures. The tray comprises an upper jaw tray, a lower jaw tray, an occlusion positioning needle, an occlusion positioner and an external interface, the bottom surface of the upper jaw tray is a occlusal plane plate, the occlusion positioner is arranged on the occlusal plane plate, andthe lower jaw tray is connected with the occlusion positioner through the occlusion positioning needle; an external interface is arranged at the front end of the upper jaw tray and is connected witha handle interface or a face arch interface; one end of the handle connector can be inserted into the outer connector and fixed, the other end of the handle connector clamps the middle end of a face arch ruler, and the face arch ruler is parallel to the occlusal plane plate. One end of the face bow interface can be inserted into the external interface and fixed; by using the tray provided by the invention, a position relationship between the upper jaw and the lower jaw and the occlusal plane can be accurately obtained, and the subsequent prosthesis manufacturing process is simplified while thenumber of times of reexamination of a patient is reduced, so that an occlusion relationship of the final prosthesis is more accurate.

Description

technical field [0001] The invention relates to the field of denture production devices, in particular to a centric jaw tray, a use method and a production method applied to digital complete dentures. Background technique [0002] At present, with the aging of the population, the number of patients with edentulous and edentulous jaws is also increasing. In the process of various restorations, with the increase in the number of edentulous, the corresponding positional relationship between the upper and lower jaws of patients is gradually lost. There are several ways to measure the patient's median position and occlusal plane to guide the arrangement of artificial teeth: [0003] The traditional method is generally to make a joint base based on the plaster model made by the doctor in the patient's mouth, place a wax embankment on the joint base, and determine the relationship between the upper and lower jaws through the adjustment of the wax embankment in the mouth. This met...

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
