Abstract

The invention discloses a non-Newtonian fluid-based motion tooth protection tooth socket which has two types of a single surface and a double surface and corresponds to different motion requirements, and comprises an outer wall (1), a non-Newtonian fluid buffer layer (2), an occlusal surface (3), an inner wall (4) and a V-shaped intra-labial ligament bayonet (5). The whole tooth socket is U-shaped and is matched with the tooth arrangement shape of a human tooth; the inner wall, the occlusal surface and the outer wall form a concave alveolus, a cavity is reserved in the middle of the outer wall, and a V-shaped intra-labial ligament bayonet is arranged in the middle of the upper end of the outer wall; the non-Newtonian fluid fills the cavity in the outer wall. The invention can keep the original shape under high-speed impact based on the characteristic of non-Newtonian fluid, plays a remarkable buffering role and protects teeth from oral cavity injury.

Description

Motion protects tooth facing based on non-Newtonian fluid

Technical Field

The invention belongs to the technical field of motion safety protection, and relates to a motion tooth protecting tooth socket. The tooth socket buffer layer can effectively resist external impact force and protect teeth and oral cavities.

Background

In daily production and life, accidents of falling off and oral cavity bite caused by the impact on teeth occur, and the teeth are more easily damaged particularly in high-confrontation sports such as boxing, basketball, free combat, rugby and the like. Tooth loss causes inconvenience to life and high medical and care costs. The tooth protecting tooth socket can protect teeth during the movements and simultaneously avoid injuries such as oral cavity bite, cerebral concussion and the like.

The protection capability of the existing tooth protecting tooth socket for sports to external impact is often related to the material and the thickness of the tooth protecting tooth socket, when the material is the same, the protection capability is improved by increasing the thickness of the tooth protecting tooth socket, but the comfortable feeling and sports of people are affected by the overlarge thickness of the tooth protecting tooth socket, and in some fierce high-resistance sports, the protection capability to the impact is limited.

Disclosure of Invention

In order to improve the impact protection capability of the tooth protection tooth socket, the invention provides a non-Newtonian fluid based moving tooth protection tooth socket.

The invention realizes the purpose through the following technical scheme:

a motion tooth protecting tooth socket based on non-Newtonian fluid has a single-side type and a double-side type, and comprises an outer wall (1), a non-Newtonian fluid buffer layer (2), an occlusal surface (3), an inner wall (4) and a V-shaped intra-labial frenum bayonet (5). The whole tooth socket is U-shaped and is matched with the tooth arrangement shape of a human tooth. The inner side and the outer side of the occlusal surface are respectively and vertically connected with the inner wall and the outer wall to form a concave alveolus. A cavity is reserved in the middle of the outer wall, and a V-shaped intra-labial lacing bayonet is arranged on the upper surface of the front end. The non-Newtonian fluid buffer layer is located in the cavity in the middle of the outer wall.

Preferably, the inner wall, the occlusal surface and the outer wall can be made of EVA (ethylene-vinyl acetate copolymer) materials, the EVA is safe and odorless, the hardness is moderate, the plasticity is high, the reshaping is allowed, the EVA is placed in a mouth after being soaked in hot water, the EVA can be reshaped according to the tooth shape, the fixing is facilitated, and meanwhile, the comfort level is improved. And a cavity is reserved in the middle of the outer wall and is used for filling non-Newtonian fluid to serve as a buffer layer.

Preferably, the non-Newtonian fluid is obtained by thoroughly mixing silicon dioxide micro-particles and polyethylene glycol, and the two substances and the mixture thereof are non-toxic and harmless to human bodies.

Preferably, the non-Newtonian fluid is injected into the cavity in the outer wall through the V-shaped intra-labial ligament bayonets on the outer wall, and the injection port is sealed through high temperature.

The invention has the beneficial effects that: when the tooth socket is impacted violently, the viscosity of the non-Newtonian fluid layer in the tooth socket is instantly enhanced under high-speed impact, so that the tooth socket keeps the original shape, the protection capability of the tooth socket on limited thickness is improved, the damage of tooth injury, oral cavity bite, cerebral concussion and the like is avoided, and the effect is better than that of a common tooth socket with the same thickness.

Detailed Description

The following detailed description of the invention refers to specific examples to assist those skilled in the art in further understanding the invention, but are not intended to be limiting in any way. Several variations and modifications are possible in light of the present claims and are within the scope of the invention.

Example 1

As shown in figures 1, 2 and 3, the non-Newtonian fluid based one-sided type sports tooth protection mouthpiece is provided. Comprises an outer wall (1), a non-Newtonian fluid buffer layer (2), an occlusal surface (3), an inner wall (4) and a V-shaped intra-labial ligament bayonet (5). The tooth socket is U-shaped and matched with the tooth arrangement shape of a human. The inner side and the outer side of the occlusal surface (3) are respectively vertically connected with the inner wall (4) and the outer wall (1) to form a concave alveolus. The V-shaped intra-labial ligament fluid is characterized in that a cavity is arranged in the middle of the outer wall (1), the upper surface of the front end is provided with the V-shaped intra-labial ligament bayonet (5), an opening (6) in the bayonet (5) is communicated with the cavity layer in the middle of the outer wall (1), the non-Newtonian fluid (2) is injected from the opening (6), and the non-Newtonian fluid is sealed through high temperature after being filled.

Example 2

As shown in FIG. 4, a double-sided non-Newtonian fluid based sports mouthpiece having upper and lower sides, each of which has a structure and a non-Newtonian fluid layer, is the same as the single-sided sports mouthpiece described in example 1. Two ends of the occlusal surface of the upper surface and the lower surface are respectively connected to form a whole.
