Description

Technical Field

[0001] This utility model relates to the field of dental bionic device technology, and in particular to an inclined tooth arrangement structure and an artificial oral cavity machine. Background Technology

[0002] An external artificial oral cavity machine is a device designed based on the actual human oral cavity to simulate the human oral cavity's chewing process. It can be used to study the release of nutrients, active substances, toxic substances, and food contaminants, as well as saliva impregnation and oral chewing digestion. Currently, external artificial oral cavity machines generally use bionic teeth for chewing food, with the upper and lower teeth typically positioned vertically and directly opposite each other, making the chewed food bolus more similar to that of a human.

[0003] In existing bionic teeth, each tooth has four cusps. The upper bionic tooth 4 and the lower bionic tooth 5 interlock during chewing. (See attached diagram.) Figure 1 As shown, when using bionic teeth to chew a lot of food, the occlusal position of the teeth is unstable, and there are cases of incorrect occlusion, which causes some food to be unable to be chewed or not broken down enough, requiring longer chewing time and greater chewing force. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the existing technology where the occlusal position of the prototyping teeth is unstable, resulting in food not being able to be chewed or not being broken down sufficiently.

[0005] To solve the above-mentioned technical problems, this utility model provides an inclined tooth arrangement structure, comprising:

[0006] The jaw assembly includes a pair of first mounting slots and a plurality of first teeth. The first teeth have first cusps on their chewing side. The pair of first mounting slots are arranged in parallel. The first mounting slots are fitted with a plurality of first teeth along their length axis.

[0007] The maxillary assembly includes a lower pressure seat and a plurality of second teeth. The lower pressure seat has a pair of second mounting slots on its surface, which are arranged parallel to each other. The lower pressure seat is positioned at the top of each second mounting slot, which is directly opposite to the first mounting slot. A plurality of second teeth are embedded in each second mounting slot along its length axis. The chewing side of each second tooth has a second cusp. The second teeth are inclined relative to the height axis of the second mounting slot. The horizontal distance between two first teeth is less than the horizontal distance between two second teeth.

[0008] The lower jaw assembly fits into the upper jaw assembly, causing the first cusp to overlap with the second cusp.

[0009] In one embodiment of the present invention, the jaw assembly further includes a support seat, which is fitted onto the outside of the lower pressure seat, and the first mounting groove is embedded in the support seat.

[0010] In one embodiment of the present invention, the support base is provided with a fixing groove that mates with the first mounting groove, and the fixing groove extends through the support base.

[0011] In one embodiment of this utility model, the height of the fixing groove is equal to the height of the first mounting groove.

[0012] In one embodiment of the present invention, a feed inlet is provided on one side of the support base, and a discharge outlet is provided on the other side of the support base.

[0013] In one embodiment of this utility model, a fixing block is provided on the lower pressure seat, and an elastic element is provided inside the fixing block. The axial direction of the elastic element is perpendicular to the length direction of the first mounting groove.

[0014] In one embodiment of the present invention, the first tooth is detachably connected to the first mounting groove, and the second tooth is detachably connected to the second mounting groove.

[0015] In one embodiment of the present invention, a filler is provided between the first tooth and the first mounting groove.

[0016] In one embodiment of this utility model, four of each of the first and second tooth cusps are provided.

[0017] An artificial oral cavity machine includes the aforementioned inclined tooth arrangement structure.

[0018] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0019] The present invention relates to an inclined tooth arrangement structure and an artificial oral cavity machine. In this invention, the distance between the first teeth on both sides of the lower jaw is smaller than the distance between the second teeth on both sides of the upper jaw. At the same time, the second teeth of the upper jaw are inclined. When the upper and lower jaws bite, the staggered first and second tooth cusps will completely fit together, making the bite of the first and second teeth tighter and increasing the contact area of ​​the first and second teeth. When chewing food, this can enhance the food crushing effect and improve chewing efficiency. Attached Figure Description
