摘要： A jaw repositioning appliance has a maxillary plate fit to a maxilla, a mandibular plate fit to a mandible, and at least one connecting wire constituted with a wire rod, which has the Young's modulus of 100 GPa or lower, which has tensile strength value of 0.01 or higher with respect to the Young's modulus, and which can deform elastically. The connecting wire has at least one curved portion. One end (34, 44) of the connecting wire is attached to the maxillary plate and the other end of the connecting wire is attached to the mandibular plate.

摘要： The present invention provides a biocompatible material in which a hydrophilic substrate is protected by a metal film, the metal film being dissolved when the biocompatible material is used in a living body environment, enabling the protected hydrophilic substrate to be used in a state in which hydrophilicity is retained. The present invention provides a biocompatible material having: a biocompatible substrate that has a hydrophilic surface; and a metal film provided on the surface of the substrate, the metal film having the dissolution characteristic of dissolving in body fluids or simulated body fluids.

摘要： The present invention provides a dental member, which has a reduced size, and thus prevents damages to tooth roots upon implantation, has high strength and low elasticity, and is excellent in engraftment stability after implantation. The dental member is produced with an amorphous alloy having a composition represented by formula: ZraNibCucAld [wherein “a” ranges from 60 to 75 at. %, “b” ranges from 11 to 30 at. %, “c” ranges from 1 to 16 at. %, and “d” ranges from 5 to 20 at. %] and is used as an orthodontic anchor screw wherein the screw part has a core diameter of 0.5-1.0 mm or a length of 2-5 mm, a one-piece-type dental implant wherein the screw part has the largest diameter of 0.5-2.9 mm and a length of 2-13.4 mm, or a two-piece-type dental implant wherein the screw part has the largest diameter of 0.5-2.9 mm and a length of 2-5.9 mm.
