ABSTRACT:
An implant for an artificial tooth suitable for insertion into a jaw portion of low height includes a circular dish-shaped outer portion having a concave surface towards the tooth to be attached and a convex surface adjoining a concave surface provided in the bone surface, and a short anchor pin extending from the center of the convex surface of the dish for insertion into a drilled bore in the bone. A tapped bore extends from the center of the dish into the anchor pin and permits firm mounting of an abutment to the implant by a screw inside a cavity in the abutment. The abutment has a concave bottom surface which permits its attachment to the implant at a certain angle. The dish-shaped portion includes four bores arranged around its center serving for firm attachment of the implant to the bone by four small screws.
