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. The chin implant assembly includes a pair of laterally spaced cortical screws with axial bores threaded fully into the exposed jawbone. A formed implant of resilient material engages the exposed jawbone and a pair of mount posts are retained in the implant and guidably positioned within the cortical bone screws.
