Detailed Description

To facilitate an understanding of the present invention, the following description is made in conjunction with the accompanying drawings and examples.

Referring to fig. 1, the invention provides a composite mouthpiece 1 with an adsorption storage function, which comprises a mouthpiece body 11 and a dental socket 12 formed in the mouthpiece body 11, wherein the mouthpiece body 11 is formed by preparing a composite sheet layer comprising a membrane layer and an adsorption layer, the surface of the mouthpiece body 11, which is in contact with teeth, is the adsorption layer, the surface of the mouthpiece body 11, which is away from the teeth, is the membrane layer, the adsorption layer is polyurethane with hydrophilic groups, and the adsorption layer is used for adsorbing functional liquid medicine for treating teeth.

In the embodiment of the invention, the section of the tooth socket body is U-shaped, and the tooth sockets are customized according to different tooth shapes of people; the tooth socket body is placed in a mold through a membrane layer and an adsorption layer which are in face-to-face butt joint with the tooth jaw model, and then is subjected to plastic suction molding; the diaphragm layer is made of polyurethane, polyethylene glycol terephthalate-1, 4-cyclohexane dimethanol ester or polycarbonate, is made of medical grade materials, and is used for ensuring the wearing safety of the composite tooth socket through a biocompatibility test.

In the embodiment of the invention, the adsorption layer belongs to a medical material, has good biocompatibility, and is safe and high in comfort; specifically, The polyurethane having a hydrophilic group is TPU (hydrogel) of The Lubrizol Corporation.

The membrane layer and the adsorption layer are both made of thermoplastic materials, and the membrane layer and the adsorption layer can be connected into a whole through hot melting by utilizing the characteristics of softening by heating and hardening by cooling of the thermoplastic materials, so that no butt joint exists, the integrity is good, and the firmness is high.

In the embodiment of the invention, the thickness of the adsorption layer is 0.2-0.7 mm, and the thickness of the diaphragm layer is 0.3-0.8 mm; preferably, the wall thickness of the tooth socket body is 0.7-1.5 mm. Preferably, the thickness of the adsorbent layer is 0.3mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm or 0.65 mm. The membrane layer has a thickness of 0.4mm, 0.5mm, 0.6mm, 0.67mm or 0.76 mm.
