Temperature modification of a hot glue gun for use with modeling plastic impression compound.

C C Modeling plastic impression compound (MPIC) is defined as a thermoplastic dental impression material composed of wax, rosin, resins, and colorants.1 Low-fusing compound (type 1) is used for border molding and impressions. Flow and reproducibility of surface detail are important characteristics of these materials.2 Border molding with MPIC can record accurate border detail; however, it can be difficult to use and messy when manipulated over a flame. Some techniques have been described to facilitate the use of MPIC by placing the compound in a syringe and heating it in a water bath.3,4 Although these techniques may be helpful, waiting for the compound to melt is time consuming. Also, the syringes filled with compound must continually be reintroduced into the water after each use so that the compound does not solidify. Hot glue guns are designed to melt a thermoplastic adhesive that comes in the form of sticks. A continuous Temperature modification of a hot glue gun for use with modeling plastic impression compound
