Intervertebral prosthesis ( 1 ), in particular intervertebral disk prosthesis, with a central axis ( 6 ) and comprising A) a first prosthetic component ( 2 ) having a first apposition surface ( 4 ) and a first inner surface ( 7 ), both being disposed transversely to the central axis ( 6 ) and having a spherical recess ( 11 ); B) a second prosthetic component ( 3 ) having a second apposition surface ( 5 ) and a second inner surface ( 8 ) both being disposed transversely to the central axis ( 6 ) and having a calotte ( 9 ) congruent with said recess ( 11 ); C) the first and second prosthetic components ( 2;3 ) being connectable in an articulated manner by means of the calotte ( 9 ) which may be slidably received in the recess ( 11 ); whereby D) the first and second prosthetic components ( 2;3 ) have a width B and a length H each being transverse to the central axis ( 6 ), said first and second prosthetic components ( 2;3 ) further comprise a longitudinal axis L<;SUB>;1<;/SUB>;, respectively L<;SUB>;2 <;/SUB>;extending parallel to the respective length H; and whereby E) the length H is greater than the width B, such that the prosthetic components ( 2;3 ) may be put into a position in the intervertebral space in which the two longitudinal axes L<;SUB>;1 <;/SUB>;and L<;SUB>;2 <;/SUB>;intersect each other at an angle alpha>;0° when being projected in a plane being orthogonal to the central axis ( 6 ).인공관절은 기질부에 서로 협력하는 관절표면층(10,11)이 구비되는 최소한 두개의 몸체(2,3)로 구성된다. 상기 관절표면층들 중 최소한 한개는 비결정질 다이아몬드상 탄소(amourphus diamond-like carbon); 또는 티타늄-질소 합금(TiN)으로 형성되어 상기 기질부에 접합되는 접합층(12,13)을 포함한다. 상기 인공관절은 마멸분의 수를 줄여주고, 향상된 모의시험 특질을 보여준다.
