[0002] Dentures are artificial restorations used to replace missing teeth or completely lost teeth. Ceramic teeth are often used as a form of dentures to replace missing or damaged teeth;

[0003] When making dentures, a mold manufacturing method is generally used. After the dentures are demolded, the rough mold of the dentures generally needs to be polished and cut to improve the comfort of the patient. However, in the existing technology, when polishing and cutting the dentures, the dentures are usually pinched directly by hand, and then fine-processed by a small electric saw or a grinding head. This processing method can easily cause the processing tools to injure the fingers, and a long processing time will cause sore fingers and unstable grip, resulting in the denture falling and damage. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when cutting or grinding the existing ceramic dentures, fingers are generally used to hold the dentures to facilitate processing, but this is easy to cause the processing tools to hurt the fingers, and after a long processing time, the fingers are prone to soreness and unstable grip, resulting in the problem of the denture falling and being damaged.

[0005] To solve the above problems, the technical solution adopted by the utility model is a ceramic tooth cutting fixture, including a base, a cross supporting plate is fixed on the upper side of the base, a connecting platform is fixed on the upper side of the cross supporting plate, a groove is opened on the upper side of the connecting platform, a workbench is provided in the groove for limited rotation, two arc-shaped limiting slide grooves are opened on the upper side of the workbench, a fixture structure is slidably provided in the arc-shaped limiting slide groove, the fixture structure includes a slider slidably arranged in the arc-shaped limiting slide groove, a supporting column is fixed on the upper side of the slider, a rotating shaft is rotatably provided inside the supporting column, a positioning splint is fixed on the top of the rotating shaft, limiting plates are fixed on both sides of the positioning splint, a movable splint is slidably provided between the two limiting plates, a boss is fixed on one side of the positioning splint, a threaded hole one is opened on one side of the boss, an adjusting bolt is threadedly rotatably connected in the threaded hole one, and one end of the adjusting bolt is rotatably connected to one side of the movable splint.

[0006] As a further solution of the utility model: a protrusion is fixed on the side of the support column, and a second threaded hole is opened on the upper side of one end of the protrusion. A positioning bolt is rotatably connected to the thread in the second threaded hole, and the bottom end of the positioning bolt contacts the upper side of the workbench. The positioning bolt is rotated to make its bottom contact with the upper side of the workbench, thereby fixing the position of the clamp structure.

[0007] As a further solution of the utility model: two clamp structures are slidably provided in each arc-shaped limiting slide groove, and the clamp structures in the arc-shaped limiting slide groove can be adjusted to adapt to dentures with different structures.

[0008] As a further solution of the utility model: an annular plate is fixed on the lower side of the workbench near the edge to facilitate the rotation of the workbench.

[0009] As a further solution of the utility model: an anti-slip button is fixed to one end of the adjusting bolt and the positioning bolt to facilitate the rotation of the adjusting bolt and the positioning bolt.

[0010] As a further solution of the utility model: a tooth-shaped anti-skid pad is fixed on one side of the positioning splint opposite to the movable splint to facilitate clamping of the denture.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model adds a clamp structure, and fixes the denture by positioning the splint and the movable splint, so as to facilitate the grinding of the denture and the cutting and grinding of the ceramic teeth on the denture. There is no need to use fingers to fix the denture, which improves safety, and the denture will not fall off during the grinding and cutting process, reducing the probability of damage.
