Abstract

The purpose of the present invention is to provide a toothguard which has a good feeling of wearing and is not susceptible to breakage or deformation. In order to solve the problem, the tooth protector according to the present invention comprises: a pair of tooth protector main bodies comprising an upper jaw tooth protector main body to be worn on the upper jaw and a lower jaw tooth protector main body to be worn on the lower jaw; a positioning member for restricting rearward displacement of the lower jaw toothguard main body; and a support part which is disposed between the positioning member and the main body part so as to cover a part of a surface of at least one of the maxillary tooth guard main body part and the mandibular tooth guard main body part, said surface facing a surface to be worn on a tooth row, and which supports the positioning member. The support portion includes a material having a bending elastic constant different from that of the toothguard body portion.

Description

technical field [0001] The present invention relates to mouthguards. Background technique [0002] For obstructive sleep apnea syndrome, it is said that the main cause is that the mandibular retraction displaces to obstruct the airway. Therefore, various mouth guards have been proposed in order to improve obstructive sleep apnea syndrome. These mouthguards limit the rearward movement of the user's jaw, keeping the airway wide, thereby improving sleep apnea or snoring. [0003] For example, Patent Document 1 proposes a mouthpiece including a pair of mouthpiece body parts corresponding to the upper jaw and the lower jaw, and a metal connection member connecting them. The mouthpiece adjusts the relative positions of the upper mouthpiece main body and the lower mouthpiece main body through the connecting member, and displaces the lower jaw of the user wearing the mouthpiece forward. In addition, in this mouthpiece, the connecting member is fixed to the mouthpiece main body ma...
