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.
