- the bruxism-preventing device of the present invention may be used by being attached to upper or lower teeth or a misaligned tooth, or may be used by being attached to upper teeth. From the viewpoint of stability, it is preferable to use the lower teeth. Therefore, in the following embodiment, a device that is used by attaching to the lower teeth will be described.
- the bruxism prevention device 1 is formed in a substantially U-shape along the dentition, and has a protection portion 2 covering an occlusion portion of a tooth, and an engagement portion connected to an inner peripheral portion of the protection portion 2 and covering the back side of the tooth. And a stop portion 3, and has a substantially L-shaped vertical section.
- the protective part 2 has a lower layer 2 y on the side to be attached to the teeth and a contact surface with the occlusal surface of the upper teeth.
- the upper layer 2x has a two-layer structure, and the locking portion 3 is connected to the inner peripheral edge of the lower layer 2y so as to extend downward.
- the lower layer 2y of the protection section 2 and the locking section 3 are formed of a thermoplastic resin.
- a thermoplastic resin for example, a resin having a softening temperature (for example, 50 to 90 ° C.) higher than the human body temperature but lower than the boiling temperature of water is used.
- a polyurethane resin, a silicone resin, a vinyl acetate, or the like in which an ethylene-vinyl acetate copolymer is preferably used may be used.
- the upper layer 2X of the protection part 2 is formed in a planar shape from a material that does not soften at the softening temperature.
- a material of the upper layer 2X for example, an elastomer is used, and it is particularly preferable to use silicon rubber or silicone resin.
- both the upper layer 2X and the lower layer 2y may be formed of an ethylene-vinyl acetate copolymer or the like.
- the width W in the radial direction of the protection portion 2 is formed so as to be the widest on the back tooth side 2a, which is both ends of the bruxism preventer 1, and to become gradually narrower toward the front tooth side 2b at the center.
- the curved shape of the protective part 2 may be determined by referring to a lot of data, such as the arrangement of the teeth obtained through the experience of denture making, and when the curved shape is determined in this way.
- the bruxism preventive device 1 made by one mold can be applied to many people, which also helps reduce costs.
- the locking portion 3 is provided continuously with the inner peripheral portion of the protection portion 2 and covers the back side of the teeth. That is, it is formed so as to protrude downward from the lower layer 2y of the protection part 2 from the inner edge of the tooth occlusion so as to be able to contact along the back side of the arranged teeth.
- the longitudinal section of the bruxism preventer 1 is formed in a substantially L-shape.
- a locking portion 3 ′ that slightly protrudes downward may also be formed on the outer peripheral portion of the protection portion 2.
- the height of the locking portion 3 ′ on the outer peripheral side may be sufficiently shorter than the length L of the locking portion 3 on the inner peripheral side.
- the locking part 3 has a height L from the upper surface 2 X of the protection part 2 to the upper surface of the protection part 2 of 2 to 13 mm. To facilitate close contact with the back side and improve stability during mounting,
- the locking portion 3 is formed by cutting out the end portion on the back tooth side from 5 to 10 times. This is for further reducing the feeling of foreign objects when worn, and does not impair the function of the bruxism preventive device 1.
- the thickness of the protective part 2 is the combined thickness of the upper and lower layers.
- the force is 1 to 4 hidden on the back tooth side 2a, and 3 to 8 mm on the front tooth side 2b.
- the thickness on the side is 4 mm
- the thickness on the middle is about 3 mm
- the thickness on the front teeth side is about 2 to 5 times the thickness on the back teeth side. This takes into account that the bite thickness of the back teeth and the bite thickness of the front teeth are generally said to be about 1: 3-5.
- the thickness of the lower layer 2y of the protection part 2 and the locking part 3 continuously provided along the inner peripheral edge of the protection part 2 are determined by a method described later so that the bruxism prevention device 1 does not come off when sleeping. Accordingly, the thickness is set so that a tooth profile can be formed on the ethylene-vinyl acetate copolymer or the like. For example, in this embodiment, the thickness t is set to 1 to 4.
- the bruxism preventive device 1 of this embodiment may be formed in a straight plane shape. As shown in FIG. 4, the bruxism preventive device 1 may be formed so as to be slightly curved toward the protection portion 2 as it goes to the back tooth side. preferable.
- the bruxism preventer 1 Prior to use, the bruxism preventer 1 is formed with an uneven surface which engages with the user's tooth profile by the following procedure.
- the bruxism preventer 1 is immersed in hot water heated to, for example, about 50 to 90 ° C for about 10 seconds to 1 minute depending on the material used, and the bruxism preventer 1 is brought to a softening temperature. By heating, the lower layer 2y of the protection part 2 and the locking part 3 are brought into a softened state with flexibility. Prior to this, both ends of the bruxism preventive device 1 may be cut with scissors or the like so that the device can be used in a size more suitable for the user.
- the bruxism preventive device 1 is used by inserting the bruxism preventive device 1 having the uneven portion M into the oral cavity before sleep, and forming the bruxism preventive device 1 in the lower layer 2 y of the protective portion 2.
