| 摘要 |
The present invention relates to an artificial dental root for a dental implant, wherein torque progressively applied to the gum (240) and an alveolar bone (250) is reduced when an artificial dental root (200) is implanted, thereby preventing involution of the gum (240), osteolysis of the alveolar bone (250), etc, and also allowing firm connection and easy drilling. The artificial dental root of the present invention comprises: a connection part (230) for connecting a processed tooth to the upper portion thereof; and a screw part (210) formed on the outer circumferential surface for insertion and connection to the alveolar bone (250), wherein the screw part (210) has a maximum protruding part (220) having the largest bone diameter at the lower part below the upper portion, to which the processed tooth is connected, and the bone diameter is getting narrower toward both sides of the maximum protruding part (220). |
