Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a simple articulator. Background Art

[0002] Currently, an articulator is a device often used in dentistry for making dentures. It is an instrument that imitates the human upper and lower jaws and the temporomandibular joint, used to fix the upper and lower jaw models, and can simulate the movement of the lower jaw to a certain extent. By fixing the patient's model to the articulator and transferring the height and jaw position relationship of the patient's upper and lower jaws to the articulator, or by means of a facebow, the inherent positional relationship between the patient's upper jaw and the temporomandibular joint can be transferred to the articulator and maintained stable, so as to perform denture-making processes such as tooth arrangement, waxing, making wax patterns, and occlusal adjustment outside the mouth. It can be used to make complete dentures, removable partial dentures, inlays, crowns, fixed bridges, and implant dentures, etc. Various dentures completed on the articulator can conform to or be close to the actual situation of the patient.

[0003] In the related art, an articulator is disclosed, which includes an upper jaw body and a lower jaw body. At one end of the lower jaw body, two symmetrically arranged struts are provided. A connecting frame arranged in a substantially W-shaped manner is fixed between the upper ends of the two struts. At one end of the upper jaw body close to the connecting frame, a rotating member arranged in a substantially T-shaped manner is provided. On both sides of the middle position of the connecting frame, a hinge support is respectively provided. A rotating rod is rotatably connected to each of the two hinge supports. At the middle position of the rotating member, two fixing blocks are provided. The two rotating rods respectively pass through the two fixing blocks. A circle of protrusions is provided on the outer walls of the two rotating rods. A through hole arranged in a stepped shape for inserting the rotating rod is provided on each of the two fixing blocks. Springs with both ends respectively abutted against the protrusions and the through holes are sleeved on the outer walls of the two rotating rods. Nuts are threadedly connected to the ends of the two rotating rods extending out of the fixing blocks. A notch for the two hinge supports to pass through is provided at the middle position of the rotating member. When adjusting the rotation center position of the upper jaw body, loosen the nut, and the upper jaw body slides outwards to the designated position under the action of the spring and then tighten the nut. The operation is simple and is suitable for the denture test of special tooth-jaw relationships. When using the articulator, fix the denture to the upper and lower jaw bodies and rotate the upper jaw body to simulate the chewing action.
