Artificial dental root

An artificial dental root comprising a main body to be implanted into the jaw bone and an upper structure to be attached with a crown;

• wherein the main body and the upper structure are separable, and the circumference of the main body is integrally constructed of ceramic material,
• the main body comprising a larger diameter dental neck corresponding portion to be implanted into dense matter of the top of the jaw bone and a smaller diameter base of the root,
• and the part between the base and the dental neck corresponding portion is tapered;
• wherein the main body of the artificial dental root has a metallic core in the center;
• wherein a core attaching hole of an anti-rotative shape is provided in a portion including an interior and central portion of the dental neck-corresponding portion;
• an anti-rotative shaped portion which is formed in at least a part of the outer circumference of the metallic core is inserted into the anti-rotative shaped hole in order to prevent it from rotating;
• an upper end of the metallic core protrudes from the upper surface of the main body of the dental root;
• and the outer circumference of the protruded portion is formed into an anti-rotative shape and is inserted into an anti-rotative shaped hole of the upper structure.

• the main body comprising a larger diameter dental neck corresponding portion to be implanted into dense matter of the top of the jaw bone and a smaller diameter base of the root,
• and the part between the base and the dental neck corresponding portion is tapered,
• said artificial dental root formed of a material having an elasticity such that when said root is implanted, stresses resulting from application of an oblique force are concentrated in the neck corresponding portion at least a portion of which is implanted into the highly strong dense tissue of a jaw.
