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

[0105] Such as Figure 4 As shown, one end of the handle interface 1401 can be inserted into the external interface 1105 and fixed, and the other end of the handle interface 1401 clamps the middle end of the face bow ruler 1402, and the face bow ruler 1402 is parallel to the occlusal plane plate 1201;

[0106] Such as Figure 5 As shown, one end of the facebow interface 1501 can be inserted into...

Embodiment 2

[0109] Embodiment 2: A method of using the centric jaw tray, which includes the following steps:

[0110] Step 1: Assemble the upper jaw tray 1101 and the lower jaw tray 1102 into one;

[0111] Step 2: Place silicone rubber on the top surface of the maxillary tray 1101 and the bottom surface of the mandibular tray 1102 and put them into the patient's mouth to obtain the shape of the maxillary alveolar ridge and the shape of the mandibular alveolar ridge;

[0112] Step 3: Install the handle interface 1401 on the external interface 1105, connect the facebow ruler 1402 to the handle interface 1401, make the facebow ruler 1402 parallel to the occlusal plane 1201, and adjust the upper jaw tray 1101 by observing the position of the facebow ruler 1402 The front part of the facebow ruler 1402 is parallel to the pupil line, and the side is parallel to the nasal alar tragus line;

[0113] Step 4: Separate the maxillary tray 1101 from the mandibular tray 1102, insert the tracing needle ...

Embodiment 3

[0115] Example 3, a multifunctional final impression device

[0116] Such as Figure 6-7 As shown, a multi-functional final impression device, which includes a maxillary base 2101, a mandibular base 2102, a maxillary dentition 2201, a mandibular dentition 2202, and an external interface 2103. The bottom of the maxillary base 2101 is provided with matching maxillary teeth The maxillary dentition interface 2104 of row 2201, the top of the mandibular base 2102 is provided with the lower jaw dentition interface 2105 matching the lower jaw dentition 2202;

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...
