Abstract
In one embodiment, a dental bur includes a proximal shank, an intermediate cutting section, and a smooth, rounded distal tip. The cutting section includes (i) a frustum-shaped portion connected at its larger-diameter end to the shank and (ii) a curved portion that provides a transition between the smaller-diameter end of the frustum-shaped portion and the rounded tip, where the outer surfaces of the frustum-shaped portion and the curved portion are both sufficiently abrasive to remove bone tissue due to the presence of surface grit and/or flutes that provide bone-cutting edges. The dental bur reduces and flattens the bone tissue of the maxillary and mandibular bones for surgical dental implants without unwanted soft tissue damage.
Claims22
A bone reduction bur for preparing a site of a surface of a jaw bone prior to dental implant placement, said surgical bone reduction bur comprising:
- a proximal shank;
- an intermediate cutting section connected to the shank;
- and
- a distal tip connected to the cutting section, wherein:
- the distal tip has a smooth, rounded portion shaped to displace gingival tissue away from the cutting section;
- and
- the cutting section comprises:
- a frustum-shaped portion having a larger-diameter end and a smaller-diameter end;
- and
- a curved portion that extends from (i) the smaller-diameter end of the frustum-shaped portion to (ii) the tip, wherein the entire surface of the curved portion is concave, relative to a location outside the bone reduction bur and directly adjacent to the curved portion of the bone reduction bur, the curved portion is shaped to fit a corner of a crest and an inside wall of the jaw bone, and the outer surface of the frustum-shaped portion and the outer surface of the curved portion are both sufficiently abrasive to remove bone tissue from the site of the bone surface that is being prepared for dental implant placement.
