Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a denture articulator. Background Art

[0002] Dentures, commonly known as false teeth, are dentures that replace teeth when they are missing. Dentures are basically divided into fixed dentures, implant dentures, and removable dentures according to their functions and effects. The denture articulator is an instrument that imitates the upper and lower jaws and temporomandibular joints of the human body to fix the upper and lower jaw models and occlusal support, and can simulate the movement of the mandible to a certain extent. The patient's model can be fixed to the articulator, and the patient's upper and lower jaw height and jaw position relationship can be transferred to the articulator. The inherent position relationship of the patient's maxilla to the temporomandibular joint can also be transferred to the articulator with the help of a face bow and kept stable, so that denture production processes such as tooth arrangement, waxing, wax model making, and bite adjustment can be carried out outside the mouth.

[0004] Although the above-mentioned denture articulator is relatively simple to fix the jaw of the denture plaster model, the general denture articulator uses a hinge to connect the two bite plates, which easily leads to the inability to adjust the relative position of the bite plates as needed during use, causing inconvenience in use. Therefore, we propose a denture articulator. Utility Model Content

[0013] Preferably, a tensile structure is formed between the support column and the telescopic column, and the support column is fixed relative to the telescopic column by bolts.

[0014] Preferably, the adjusting bolts pass through the interior of the positioning bearing and the fixing nut respectively, and the positioning bearing and the fixing nut are fixedly connected to the upper end plate and the lower end plate respectively.

[0015] Preferably, the positioning plates are symmetrically distributed about the vertical center lines of the lower end plate and the upper end plate, and the positioning plates are fixed relative to the lower end plate and the upper end plate respectively through positioning bolts and positioning holes, and the positioning holes are equidistantly distributed.

[0016] Compared with the prior art, the present invention provides a denture articulator with the following beneficial effects:

[0017] The utility model adjusts the relative position of the lower end plate and the upper end plate by turning the adjusting bolt, which cooperates with the fixing nut. The positioning bolt can cooperate with the corresponding positioning hole according to the relative position of the lower end plate and the upper end plate, and the lower end plate and the upper end plate are relatively fixed by the positioning plate, so that the relative position of the occlusal plate can be adjusted according to needs, avoiding the problem that the general denture articulator uses a hinge to connect the two occlusal plates, which easily leads to the inability to adjust the relative position of the occlusal plates according to needs during use, causing inconvenience in use.
