Abstract
A dental instrument having a two-shot molded handle and methods for making the same. The dental instrument includes a dental instrument shank of metal with a handle formed near the proximal end of the shank. The handle includes a first polymer formed over a portion of the shank, and a second polymer formed over at least a portion of the first polymer. The first polymer may be rigid so as to more firmly attach to the shank and better resist torsional and/or tensional slippage between the shank and handle during use, while the second polymer may be flexible so as to increase gripability and comfort during manual use of the instrument. The first and second polymers may be of different colors to provide contrast (e.g., to highlight characters formed in the first rigid polymer).
