Bone carving tool for creating convex ridge for inner border of initial hole for placement of implant hole

摘要

The present invention relates to a bone carving tool for creating a convex ridge for the inner border of the initial hole for placement of an implant hole, and comprises: a bone carving unit with tapering diameters ranging from 2 to 7 mm, which has a plurality of triangular-shaped projections disposed on the lateral sides thereof forming a triangular prism-shape; and a supporting portion for supporting the bone carving unit connected to the bone carving unit at a lower aspect thereof, wherein the diameter of the bone carving unit gradually narrows towards the upper aspects thereof and the uppermost aspects of the plurality of triangular-shaped projections and the triangular prism-shape coalesce to a single point.

1. A bone carving tool for creating a convex ridge for an inner border of an initial hole for placement of an implant hole, the tool comprising:
a bone carving unit; and a supporting portion for supporting the bone carving unit and connected to a lower part of the bone carving unit, wherein the bone carving unit has a diameter ranging from 2 mm to 7 mm and includes a bone carving unit body having a plurality of triangular shaped projections formed in a radial shape, and an upper end portion having a plurality of triangular shaped projections formed in the radial shape corresponding to the plurality of triangular shaped projections of the bone carving unit body, wherein a size of each of the plurality of triangular shaped projections of the bone carving unit body becomes smaller towards an upper end of the bone carving unit as the diameter of the bone carving unit becomes smaller towards the upper end of the bone carving unit, wherein a tilt angle of each of the plurality of triangular shaped projections of the upper end portion is different from a tilt angle of each corresponding triangular shaped projection of the plurality of triangular shaped projections of the bone carving unit body so that the plurality of triangular shaped projections of the upper end portion coalesce to a single point at the upper end of the bone carving unit, wherein each of the triangular shaped projections of the bone carving unit body has two flat sides extending from the lower part of the bone carving unit toward the upper end portion of the bone carving unit, and where the number of the triangular shaped projections of the bone carving unit body is five or more, and the number of the triangular shaped projections of the upper end portion is five or more.
