Claims8
A tissue stabilizing accessory for a dental hand drill having a drill bit and employed essentially for drilling through the gum and bony cortex of the jaw comprising:
- a mounting member for fixedly securing the accessory to the dental drill for non-rotatable movement therewith;
- compression spring means fixedly supported on said mounting member for coaxial alignment with the drill bit in spaced relationship thereto and;
- a tissue compressing pressure foot fixedly mounted on said spring means remote from said mounting member and having a tissue contacting face for engagement with the gum and an axial bore only slightly larger in diameter than the drill bit and extending centrally through said face, said pressure foot being configured so as to impart controlled pressure through said compression spring means to the gum engaged by the tissue contacting face adjacent said bore.
A method of stabilizing gum tissue and guiding the drill bit of a dental drill when drilling through the gum and bony cortex of the jaw comprising the steps of:
- providing a tissue stabilizing accessory for a dental drill comprising a mounting member, a tissue compressing pressure foot, and compression spring means interconnecting said pressure foot and said mounting member, said foot having a tissue contacting face and a central bore extending therethrough to permit passage of the dental bit therethrough for drilling;
- mounting the accessory on the dental drill for non-rotatable movement therewith;
- engaging the tissue with said tissue contacting face;
- extending the drill bit through the bore while compressing the contacted tissue and maintaining the compression on said tissue while drilling.
