Abstract: A coupling member includes a sliding member and a sleeve. The sliding member has one axial direction end portion coupled to a first attachment portion provided at a first attachment that is mounted to one of a maxilla or a mandible. The sleeve has one axial direction end portion coupled to a second attachment portion provided at a second attachment that is mounted to the other of the maxilla and the mandible. The sliding member is inserted into the sleeve so as to be slidable. A restricting section is formed at the sleeve between two axial direction end portions of the sleeve so as to restrict sliding of the sliding member in both directions along an axial direction of the sliding member.

Abstract: A dental coupling member which can easily adjust the position of the lower jaw of the user without increasing the size of the coupling member is provided. The dental coupling member is attached to upper and lower oral appliances to couple them, and regulates displacement of the lower oral appliance to rear side. The dental coupling member has; an outer which is a cylindrical member having a through hole, to be attached to one oral appliance; an inner having a rod-shaped insertion portion to be inserted into an interior of the cylindrical portion and slidably held by the outer, the inner to be attached to the other oral appliance; and a stopper adjustably positioned inside the cylindrical portion, the stopper serve to limit a slide width of the insertion portion inside the cylindrical portion by adjustment of its position along the axial direction of the cylindrical portion.

Abstract: A method of healing an external wound involves applying an external wound-healing agent to an external wound, or bringing the external wound-healing agent applied to a substrate into contact with an external wound, wherein the external wound-healing agent includes, as an active ingredient, at least one compound of a glycerol alkyl ester represented by defined Formula (I) or a diglycerol alkyl ester represented by defined Formula (II). In a further embodiment, the method involves bringing a fiber aggregate or a film into contact with an external wound, wherein the fiber aggregate or the film each includes a thermoplastic resin and at least one compound of the glycerol alkyl ester or the diglycerol alkyl ester.

Abstract: A mouthpiece including a constituent portion (X) that includes an olefin-based polymer (A) having a repeating unit having 2 or 3 carbon atoms and that satisfies a bending elastic modulus (?) at 23° C. of 80 MPa???1000 MPa.

Abstract: The mouthpiece according to a first aspect of the present invention comprises a pair of opposing upper jaw mouthpiece and lower jaw mouthpiece, a pair of positioning members that is provided in either one of the upper jaw mouthpiece and the lower jaw mouthpiece and to be able to carry out positional adjustment in a front-back direction, and a pair of stoppers that is provided in the other one of the upper jaw mouthpiece and the lower jaw mouthpiece, regulates a rearward displacement of the lower jaw mouthpiece by coming into abutment with the positioning members, and regulates lateral displacements of the upper jaw mouthpiece and the lower jaw mouthpiece by coming into abutment with the either one of the upper jaw mouthpiece and the lower jaw mouthpiece.

Abstract: A mouthpiece with which the advancement amount of a lower jaw mouthpiece can be more easily adjusted, without increasing the size of the mouthpiece, is provided. The mouthpiece has: a pair of upper jaw and lower jaw mouthpieces facing each other; a male screw; a female screw; a front holding part provided to one of the mouthpieces, holding the male screw or the female screw; and a rear holding part provided to the other mouthpiece, holding the female screw or the male screw further rearward than the front holding part. The female screw and the male screw position the lower jaw mouthpiece in the front-rear direction with respect to the upper jaw mouthpiece, as a result of the turning of the male screw which is screwed into the female screw at a denture tooth surface or further rearward than the denture tooth surface.
