Description

  The present invention relates to a bite tightening suppressor that suppresses the expression of muscle / fascial pain by suppressing the act of biting.

  Conventionally, the presence of pain called muscle / fascial pain is known, but the cause of this muscle / fascial pain is the muscle that controls the movement of the jaw by unconsciously biting the teeth. It is considered that excessive stress is applied to the skin, and pain such as headache is caused based on this stress.

  Therefore, it has been proposed to eliminate the headache by suppressing the occurrence of stress by using a mouthpiece.

Specifically, the mouthpiece is composed of a U-shaped frame having a length of a dentition composed of a plurality of teeth, and an elastic material attached to the inside of the frame. In order to maintain the shape, a relatively hard material such as a plastic material is used (for example, see Patent Document 1).
Japanese National Patent Publication No. 10-509084

  However, when a mouthpiece made of an elastic material is attached to a tooth, if an unintentional involuntary strong bite appears, excessive mechanical pressure is developed in the temporomandibular joint, and this pressure is reduced. There was a risk of new displacement or pain in the temporomandibular joint.

  Therefore, in the clenching suppressor of the present invention, the first plate portion that contacts the inner surface of the tooth, the second plate portion that contacts the outer surface of the tooth, and the first plate portion and the second plate portion are connected. It is a clenching suppressor that can be attached to teeth as a portal with the third plate portion, and the third plate portion is made of an elastic material.

Furthermore, the clenching suppressor of the present invention is also characterized by the following points. That is,
(1) The third plate portion has a thickness of 0.5 mm or less at the maximum deformation.
(2) The third plate portion is made of polyurethane foam.
(3) The first plate portion, the second plate portion, and the third plate portion are integrally formed of polyurethane foam.
(4) A through hole is provided in at least one of the first plate portion, the second plate portion, and the third plate portion.
(5) The first plate portion and the second plate portion are provided with engaging protrusions that engage with the undercut of the tooth neck portion or the interdental space.

  According to invention of Claim 1, the 1st board part contact | abutted to the inner surface of a tooth | gear, the 2nd board part contact | abutted to the outer surface of a tooth | gear, and the 1st board part which connects a 1st board part and a 2nd board part are connected. It is a clenching suppressor that can be attached to teeth as a portal with three plate parts, and the third plate part is made of an elastic material so that the bite suppressor is mounted when the mouth is closed Persistent periodontal sensation can be induced for the paired teeth that become occluded. Therefore, the onset of muscle / fascial pain can be suppressed by maintaining the lower jaw position without the user of the clenching suppression tool biting. In particular, when unintentional involuntary strong biting occurs, it is possible to avoid applying excessive force to the temporomandibular joint due to elastic deformation of the elastic material.

  According to a second aspect of the present invention, in the clenching suppressor according to the first aspect, the thickness of the third plate portion is 0.5 mm or less when the third plate portion is maximum deformed, so that the user of the clenching suppressor is involuntary. When a strong bite appears, the thickness of the third plate is 0.5mm or less, and it hardly affects the occlusal relationship between the upper and lower jaws and induces a new displacement or pain in the temporomandibular joint Can be surely prevented.

  According to the invention described in claim 3, in the clenching suppressor according to claim 1 or 2, the third plate portion is made of foamed polyurethane, so that the restorability after deformation by biting is high, It can withstand relatively long periods of use for more than one day.

  According to the invention described in claim 4, in the clenching suppressor according to claim 1 or 2, the first plate portion, the second plate portion, and the third plate portion are integrally formed of foamed polyurethane. Therefore, it is possible to easily manufacture the bite restraining tool and to provide an inexpensive bite restraining tool. In addition, when integrally molded with foamed polyurethane, the contact with the teeth by the first plate portion and the second plate portion can be improved, it can be difficult to come off from the teeth, and different teeth of individuals It is only necessary to provide a clenching suppressor that can improve the follow-up to the shape and that is different in size only in stages.

  According to invention of Claim 5, in the clenching suppression tool of any one of Claims 1-4, at least any one of a 1st board part, a 2nd board part, and a 3rd board part. By providing the through hole in the one, it is possible to ensure the safety when accidentally swallowing the biting suppressor.

  According to a sixth aspect of the present invention, in the clenching suppressor according to any one of the first to fifth aspects, the first plate part and the second plate part include a tooth neck part or an interdental space. By providing the engagement protrusion that engages with the undercut, it is possible to prevent the occlusion suppressor from falling off from the teeth.

  The clenching suppressor of the present invention suppresses biting by using it while it is attached to a tooth, thereby suppressing the occurrence of muscle / fascial pain, etc. As shown in FIG. A is the 1st board part 11 contact | abutted to the inner surface of a tooth | gear, the 2nd board part 12 contact | abutted to the outer surface of a tooth | gear, and the 3rd board part which connects the 1st board part 11 and the 2nd board part 12. The gate shape is a reverse U-shape when viewed from the side, and can be fitted to the teeth.

  In the present embodiment, the first plate portion 11, the second plate portion 12, and the third plate portion 13 are each formed in a flat plate shape to form a side view portal shape, but are not limited to the gate shape. The plate part 11, the second plate part 12, and the third plate part 13 may be formed in a circular arc shape when viewed from the side. In particular, since the tooth root side of the crown is thin and the tip end side of the tooth is thick, the bite restraining tool can be closely fitted to the tooth by making it arc-shaped in a side view and can be made difficult to come off. .

  As shown in FIG. 2, the clenching suppressor A of the present embodiment is used by being attached to one tooth, and the first plate portion 11, the second plate portion 12, and the third plate portion 13 are Each has a width dimension of about 10 mm that can be fitted to one tooth. In addition, when attaching to the deciduous teeth in a child, it is desirable that the bite restraining tool is further miniaturized.

  The clenching suppressor A is not limited to a form that is mounted on one tooth, and may be mounted across a plurality of teeth. However, when the width size of the clenching suppressor is increased so as to straddle multiple teeth, the size of the clenching suppressor increases, resulting in a new sense of discomfort during use. Therefore, it is desirable that the bite restraining tool A is as small as possible.

  It is desirable that the clenching suppressor A is attached to the molars so as to easily recognize the tightened state. In particular, when it is mounted on a molar, it is difficult for the third party to visually recognize the bite suppression tool A when facing the third party with the bite suppression tool A mounted. If there is no problem, it is not necessary to remove the clenching suppressor A, and it is possible to greatly reduce the trouble of frequently attaching and detaching the clenching suppressor A.

  The third plate portion 13 is made of an elastic material, and the teeth on which the bite restraining tool A is attached and the mating teeth in an occlusal state come into contact with the third plate portion 13, thereby It is possible to induce a periodontal sensation in the user and effectively suppress the occurrence of strong bite by this periodontal sensation.

  When a strong bite occurs before the periodontal sensation is induced, such as unintentionally involuntary momentary strong bite, the third plate portion 13 is elastically deformed and is caused by bite. The power can be relaxed.

  In particular, it is desirable that the elastic material constituting the third plate portion 13 has a thickness of 0.5 mm or less at the maximum deformation.

  That is, in a strong bite state, the thickness of the elastic material is 0.5 mm or less, so that it hardly affects the occlusal relationship between the upper and lower jaws and induces a new deviation or pain in the temporomandibular joint. Can be prevented.

  In addition, in order for the thickness at the maximum deformation to be 0.5 mm or less, the thickness before the deformation is naturally related, and when an elastic material having a small Young's modulus is used, the third plate portion 13 is configured to be thin. When an elastic material having a large Young's modulus is used, the third plate portion 13 is made relatively thick.

  As the elastic material to be the third plate portion 13, foamed polyurethane is suitable. Since the polyurethane foam has a large Young's modulus, even when the thickness of the third plate portion 13 is about 3 to 5 mm, the thickness at the maximum deformation can be 0.5 mm or less. In addition, the polyurethane foam is highly recoverable from the deformed state due to the bite, and can be used stably without being damaged even when used for a relatively long time of one day or longer.

  In particular, in the present embodiment, the first plate portion 11, the second plate portion 12, and the third plate portion 13 are all made of foamed polyurethane. That is, the bite restraining tool A is formed by integral molding of polyurethane foam. Thus, when the bite restraining tool A is integrally formed of foamed polyurethane, the bite restraining tool A can be easily manufactured, and an inexpensive bite restraining tool A can be provided.

  In addition, when the first plate portion 11 and the second plate portion 12 are made of foamed polyurethane, the contact area between the first plate portion 11 and the second plate portion 12 and the teeth tends to be large, so it is difficult to come off the teeth. can do.

  Furthermore, since the first plate portion 11 and the second plate portion 12 made of foamed polyurethane are easily deformed due to their large Young's modulus, it is possible to improve the followability to different tooth shapes for individual individuals. It is not necessary to form the clenching suppressor A in accordance with the shape of the teeth, and it is sufficient to provide the clenching suppressor A having a stepwise difference in size.

  In addition, a sheet material harder than foamed polyurethane is pasted on the outer surface of the first plate portion 11 and the second plate portion 12, and in some cases the third plate portion 13, and the first plate portion 11 and the second plate portion. 12 or the shape retention of the third plate portion 13 may be improved. In addition, instead of the sheet material, a frame material composed of an appropriate rod may be attached, or a coating film by an appropriate coating may be formed.

  As shown in FIGS. 1 and 2, the third plate portion 13 is provided with a through hole 13a. When the bite restraining tool A is accidentally swallowed, the through hole 13a becomes a gas or liquid flow hole. As a result, it is possible to prevent obstruction of the trachea and the esophagus. The through hole 13 a may be provided not only in the third plate portion 13 but also in the first plate portion 11 and the second plate portion 12.

  As shown in FIG. 3, the first plate portion 11 and the second plate portion 12 are provided with a first engagement piece 11a and a first engagement piece, which are engagement protrusions that protrude from the lower edge toward the contact surface side with the teeth. Two engagement pieces 12a are provided.

  As shown in FIG. 4, the first engagement piece 11a and the second engagement piece 12a are engaged with the undercut T2 of the tooth neck T1, and the first engagement piece 11a and the second engagement piece The engagement of 12a and the undercut T2 makes it difficult for the clenching suppressor A to fall off the teeth.

  In addition, as shown in FIG. 3B, the first engagement piece 11a and the second engagement piece 12a swell in the protruding direction of the first engagement piece 11a and the second engagement piece 12a on both side edges, respectively. A protruding bulge h is provided.

  The bulging portion h is further engaged with the undercut of the interdental space, thereby further preventing the occlusion suppressor A from falling off from the teeth and engaging the bite. It is possible to prevent the displacement of the crimping suppressor A from occurring.
