Embodiment 1

[0074] A kind of articulator, comprises support, and support comprises upper support 1 and lower support 2, as figure 2 , Figure 15 As shown, the lower support includes a support base 21, one end of the support base is provided with a fixed column 22 on both sides, and the opposite side of the two fixed columns is provided with a cylindrical head 23. The cylindrical head is used to slide in the track of the upper bracket cavity, and the support base The other end is provided with adjustable column 24.

[0075] The upper support includes a top plate 11, such as image 3 As shown, movable grooves 12 are arranged symmetrically at both ends of the top plate, and the upper part of the movable groove is opened, and a cavity 13 is formed inside, and a cylindrical head 23 of the lower bracket is placed in the cavity, and the cylindrical head is movably connected with the movable groove to realize the upper bracket and the lower bracket. Turn and slide.

[0076] The cavity in the ...

Embodiment 2

[0080] An articulator, its structure is as described in Embodiment 1, the difference is that the side of the baffle plate in contact with the cylindrical head is provided with a groove, and the cylindrical head slides in the groove.

Embodiment 3

[0082]An articulator, its structure is as described in Embodiment 1, the difference is that the condyle guide slot spacer is a right-angle plate, including a short plate 142 and a long plate 143 connected at a right angle, such as Figure 10 , Figure 11 As shown, the short board is connected with the movable groove wall through threads, the long board is provided with an arc-shaped slope 144, and the arc-shaped slope surface is provided with strip guide rails 141 .

Abstract

The invention relates to an articulator and a use method, and belongs to the technical field of oral rehabilitation. The articulator comprises a support, wherein the support comprises an upper support and a lower support, the lower support comprises a support base, fixed columns are arranged on two sides of one end of the support base, cylindrical heads are arranged on opposite sides of the two fixed columns, the cylindrical heads are used for sliding in a track of a cavity of the upper support, and an adjustable stand column is arranged at the other end of the support base; the upper support comprises a top plate, movable grooves are symmetrically formed in two ends of the top plate, openings are formed in upper portions of the movable grooves, cavities are formed in the movable grooves, cylindrical heads of the lower support are placed in the cavities, and the cylindrical heads are movably connected with the movable grooves and used for achieving rotation and sliding of the upper support and the lower support. A personalized artificial joint structure is formed by collecting oral cavity related information, establishing a model and applying a 3D printing technology, and natural movement of human joints is completely simulated. A denture manufactured according to the articulator is closer to an original occlusion state in the mouth, and due to high accuracy, the denture can be worn into a patient without or with a small amount of occlusal adjustment.

Description

technical field [0001] The invention relates to an articulator and a using method thereof, belonging to the technical field of oral restoration. Background technique [0002] The articulator is a simulation instrument that imitates the upper and lower jaws and temporomandibular joints of the human body to fix the upper and lower jaw models and the occlusal tray, and to a certain extent simulate the contact relationship between the upper and lower jaw teeth. Articulators play a vital role in the field of clinical restoration and are important in the study of the theory of the hinge axis in occlusion, mandibular margin movement, temporomandibular joint movement, bruxism, occlusal trauma, orthodontics, etc. Played a pivotal auxiliary role. In order to obtain the static and dynamic information of the patient's joint motion, the articulator is now widely used clinically. [0003] Articulators can be simply divided into simple dental pedestals, semi-adjustable articulators and f...
