Abstract
A dental tool with detachable saw blades and adhesively affixed abrasive strips on the distal ends of a U shaped handle for removing the solified resin in posterior and anterior teeth during the placement of porcelain and composite inlays while keeping the tongue and cheek away from the cutting surfaces. The primary function of the tool is provided by a finger rest to direct the tool force in a gingival direction with stability and control improving the function and safety of the tool.
Claims1
A dental saw and abrasive tool comprising a U shaped handle made of spring steel bent to form a pair of essentially parallel rods said rods having distal end portions bent forward to form a saw support;
- said distal end portion of said rods terminating in protruding circular pins of a reduced diameter to that of the rods;
- the parallel tool handle rods flared inwardly at approximately the vertical center of the handle;
- a thin, narrow, rectangular shaped saw blade with centered mounting holes on each end affixed to the circular protruding pins with the saw teeth facing outwardly;
- the inherent spring forces of the rods providing a tension force to secure the saw blade to the tool handle;
- and
- the saw blade affixed to the ends of the tool handle rods by compressing the rod end inwardly to accommodate the mounting holes in the saw blade;
- the improvement comprises a finger receptacle formed of a U shaped cavity with vertical side walls and a horizontal top wall fixedly attached to the center of the parallel rods for accommodating the manipulation of the tool to achieve a better control of vertical and side pressure on the tool when it is held in an operator's hand.
