Abstract: A staple which is compressively affixed to the mandibular jaw with lag screws, a drill guide apparatus having a plane guide and drilling barrel for proper alignment of the staple and a method for proper implantation of the staple. The staple is provided with a plurality of parallel transosteal pins which are mounted on a mounting axis which extends in a direction parallel to the axis of compression. The plane guide has a curvilinear aperture to extend around the jaw bone for forming a planar mating surface on the bone with a grinding tool. The drilling barrel accepts a plurality of removable sleeves for guiding drill bits of different sizes. A cap nut is self-threaded on to a smooth portion of the transosteal pin. The smooth portion of the transosteal pin is provided to reduce irritation to the gingiva and facilitate adhesion of a bioceramic or biocompatable polymer material.

A sleeve portion of the sleeve nut extends through the gingiva to reduce irritation.

Abstract: The method of applying a chin implant to a human includes stripping tissues from the lower jaw mandible to the jawbone, locating, applying and supporting a drill guide against the exposed bone at a median plane, drilling through the drill guide a pair of laterally spaced bores into the jawbone equidistant from the median plane, threading a headless cortical screw having an axial bore into each of the drilled bores, and assembling a chin implant with a pair of mount posts snugly against the jawbone while guidably positioned the posts into the screws, and suturing the stripped tissue back into normal position enclosing and retaining the implant. The drill guide has a handle with a central axis mounting a body engageable with the exposed jawbone including a locating center on its axisregisterable with the medium plane. The body has a pair of laterally spaced drill guide bores and a pair of laterally spaced chin engaging arms so that symmetrical bores can be drilled into the jawbone.

Abstract: The method of implanting an abutment device to a jawbone for anchoring a dental prosthesis comprises surgically cutting gum tissue, turning back adjacent tissue exposing the jawbone, drilling into the bone, assembling a hollow porous cylinder of titanium wire mesh having threaded therein a temporary nylon plug into the jawbone, reassembling the gum tissue to overlie the cylinder and plug. Retaining the cylinder for a healing period of several months while adjacent bone tissue grows into, around and through the cylinder mesh for a mechanical interlock therewith for anchoring the cylinder with the jawbone. Surgically reexposing the cylinder, removing the plug from the cylinder and successively threading therein an abutment device, an axial portion thereof projecting from the jawbone and gum tissue to which a dental prosthesis may be attached.

Abstract: A padded helmet for athletic events such as racquet ball, having a pair of metal wires extending between the bill of the helmet to the ear projections for protection of the eyes. The helmet is made of plastic and lined with a suitable plastic material. Cutout areas in the helmet are provided for venting. The helmet includes a dome-shaped head protective shell with a bill projecting forwardly from the end of the shell and a pair of earpieces depending from side portions of the shell. A taught wire is secured to each earpiece and extends to and is secured to a forward portion of the bill to protect the user's eyes against ball, racquet or wall impacts.
