The present invention provides a dental member which has a reduced size and therefore does not damage a tooth root upon implantation thereof, has high strength and low elasticity, and exhibits excellent engraftment stability after implantation thereof.The dental member is produced from an amorphous alloy having a chemical composition represented by the formula: ZraNibCucAld [wherein each of a, b, c and d represents a value of at.%, wherein a represents 60 to 75 at.%, b represents 11 to 30 at.%, c represents 1 to 16 at.%, and d represents 5 to 20 at.%]. The dental member can be used as an orthodontic anchor screw which has a screw part having a core diameter of 0.5 to 1.0 mm or having a length of 2 to 5 mm, a one-piece dental implant which has a screw part having a largest diameter of 0.5 to 2.9 mm and a length of 2 to 13.4 mm, or a two-piece dental implant which has a screw part having a largest diameter of 0.5 to 2.9 mm and a length of 2 to 5.9 mm.
