Abstract
Abstract A drill guide for mandibular staples is disclosed which is adapted to accurately align a drill for drilling fastener holes in the mandibular lower jaw portion at precisely located positions for the attachment of fasteners therethrough by means of a staple to retain a dental appliance in secure position on the mandibular jaw portion; the method includes the construction of a staple which has a lower cross plate which is curvilinearly shaped to conform to the curvilinear shape of the front section of the jaw bone and to which are attached a plurality of fastener members adapted to protrude into and selectively through the jaw bone in accordance with the holes previously drilled through the jaw bone by means of the drill guide; the staple and the fastening portions of the staple are coated with a bio-ceramic such as aluminum oxide, titanium oxide, magnesium oxide, or the like, applied to the staple in open pore form to permit the bone tissue of the mandibular jaw to grow into the porous bio-ceramic coating to provide an additional interlock of the staple with the mandibular jaw tissues and to prevent bone deterioration due to the drilling operation and insertion of the metal staple.

Claim 1
Independent Claim
331 words
