Technical Field

[0001] The invention belongs to the technical field of tooth product manufacturing, and in particular relates to a jaw frame. Background Art

[0002] A jaw frame is an instrumental device used to simulate the structure and function of the human masticatory organ. It has components and joints equivalent to the human masticatory organ and can simulate the movement of the upper and lower jaws to a certain extent. Therefore, the jaw frame is often used to manufacture denture molds suitable for the actual meshing conditions of the human oral cavity based on denture problems.

[0003] The existing jaw frame includes an upper fixing seat and a lower fixing seat, and the upper fixing seat and the lower fixing seat are used to simulate the upper and lower jaws of the human oral cavity. The upper fixing seat and the lower fixing seat simulate the meshing state of the denture through a rotating connecting piece. Because the meshing state of the human oral cavity is not only the upper and lower meshing, but also includes left and right, front and back meshing movements. Therefore, there is a problem of inaccurate simulation of the human oral jaw. Summary of the invention

[0004] The technical problem solved by the present invention is to provide a jaw frame to solve the problem that the jaw frames in the prior art cannot accurately simulate the meshing of the human oral jaws.
