Problems solved by technology

[0023] In order to solve the above problems, the present invention provides a Gothic bow and a method for digitally obtaining the median jaw position. Through digital design and 3D printing to personalize the Gothic bow, the cumbersome steps are simplified and the production cost is reduced. cost; through the personalized design of tracing board and tray, the present invention can deal with , cases with teeth on one side or cases with insufficient occlusal space; in addition, because the present invention is a 3D printed resin product, no metal artifacts will be produced when shooting CBCT, and it can be made by adding radiation points on the Gothic bow The gothic bow also has the function of a radiation guide, reducing the doctor's operating steps and the number of patient visits; at the same time, it can be added to the printed personalized tray The handle with the fork connected to the universal joint can save the doctor from repeatedly dismantling the tracing board and installing it in the traditional steps. Fork step, direct transfer of maxillary relationship, reducing clinical operation steps

Embodiment 1

[0114] like Figure 1-11 , 19, a method of digitally obtaining the median jaw position is actually a method of digitally obtaining the median jaw position to make dentures, using a personalized Gothic bow, which is mainly suitable for edentulous upper and lower jaws case, the specific steps are as follows:

[0115] a) Take the initial impression: use silicone rubber to make the initial impression of the patient, and obtain the preliminary occlusal height. The specific steps are as follows: adjust the patient chair position; select the appropriate tray; take the impression of the lower jaw; take the impression of the upper jaw; Embankment or bite registration; check impression.

[0116] b) on Rack: The initial impression is reproduced as a model, using the preliminary occlusal height and the upper surface of the model shelf. The steps are as follows: turn over the plaster model; model trimming; use The dyke or occlusal registration fixes the upper and lower jaws as a ...

Embodiment 2

[0128]like Figure 12-15 As shown in 、19, a method of digitally obtaining the median jaw position is actually a method of digitally obtaining the median jaw position to make dentures, using another personalized Gothic bow, which is mainly suitable for teeth on one side. In the case of edentulous on one side or insufficient distance between the jaws, compared with the upper and lower jaws being edentulous (embodiment 1), this embodiment does not Embankment, the tracing board is directly connected with the personalized tray as a whole. In this embodiment, the specific steps are as follows:

[0129] a) Take the initial impression: use silicone rubber to make the initial impression of the patient, and obtain the preliminary occlusal height. The specific steps are as follows: adjust the patient chair position; select the appropriate tray; take the impression of the lower jaw; take the impression of the upper jaw; Embankment or bite registration; check impression.

[0130] b) ...

Embodiment 3

[0142] like Figure 16-19 As shown, a method of digitally obtaining the median jaw position is actually a method of digitally obtaining the median jaw position to make dentures. It uses a standard Gothic bow and is mainly suitable for those who do not need to make very precise pressure impressions. models with sufficient distance between them. The concrete steps of this embodiment are as follows:

[0143] a) Making impression: choose a standard tray of appropriate size, if it does not fit properly, adjust the tray appropriately; use silicone rubber to make the initial impression of the patient, trim the initial impression, inject silicone rubber light-body material, and obtain the final impression mold. The steps are as follows: adjust the patient chair position; select the appropriate tray; prepare the lower jaw model; prepare the upper jaw model; check the initial impression; trim the initial impression, inject silicone rubber light-body material, and obtain the final impr...

Abstract

The invention relates to a Gothic arch and a method for obtaining long median jaw in a digitization mode. The Gothic arch comprises an upper jaw Gothic arch and a lower jaw Gothic arch; the upper jawGothic arch comprises an upper jaw tray, a radiation point, an upper jaw bite rim, an upper jaw Gothic arch tracing plate, a tracing needle and a bite fork; and the lower jaw Gothic arch comprises a lower jaw tray, a radiation point, a lower jaw bite rim, a lower jaw Gothic arch tracing plate, a centric lock disc and a retention pin. The method for obtaining the long median jaw in the digitizationmode comprises the steps that a) taking a preliminary impression; b) loading an articulator; c) designing a personalized Gothic arch in a computer-aided manner; d) preparing a final impression; e) mounting the upper jaw Gothic arch tracing plate on the upper jaw tray through the upper jaw bite rim, and mounting the tracing needle on the upper jaw Gothic arch tracing plate; f) rotating the tracingneedle to adjust the height of the tracing needle to a proper position; and g) obtaining the long median jaw and the like. The Gothic arch and the method for obtaining the long median jaw in the digitization mode can be suitable for cases without teeth on one side and with teeth on the other side or cases with insufficient occlusion space, and the number of treatment times of a patient can be reduced.

Description

technical field [0001] The present invention relates to a Gothic bow and a method for digitally obtaining the median jaw position, which is used to determine the patient's median jaw position, and finally to make dentures. In fact, it is a digital method for obtaining the median jaw position and making dentures. It belongs to the field of stomatology. [0002] technical background [0003] In the field of stomatology, for patients with fully edentulous or partially edentulous jaws, before making restorations for the patients, the most important thing is to determine the patient’s median height and median jaw position. Median jaw position refers to: when The upper and lower dentition are in contact, and the front teeth are in normal overlay covering, back teeth There is a staggered contact relationship between peaks and dimples between the surfaces, and the upper and lower For the widest contact, the position where the mandible is equivalent to the maxilla is called the ...
