<p>A dental-care device is constructed from a planar base (2) and a wire receiving part (3) positioned on the top surface of the planar base (2). Slots (4) extending straight horizontally are formed at the center of the wire receiving part (3), and wire (7) is passed through these slots. The device is preferably manufactured by a metal powder injection molding method, and is composed of metal material which contains Ti as the base component, C in an amount of from about 0.03-0.5wt% by weight of the metal material, O in an amount of from about 0.08-0.8wt% by weight of the metal material, and N in an amount of from about 0.03-0.6wt% by weight of the metal material. A large number of pores may be scattered at least in the vicinity of the surface of the metal material. This device can be easily manufactured, has a good surface wetness characteristic, and has functional portions, such as portions of low friction and portions of superior adhesiveness. <IMAGE></p> |
