The transverse strengths of three denture base resins.
Ten specimens each of (1) Lucitone 199, short- and long-cured, (2) Accelar 20, and (3) Triad materials were broken using a 3-point load on an Instron Universal testing machine after processing and air drying. Five specimens of each resin also were broken after storage in deionized distilled water at 37 degrees C for 30, 60, and 90 days. Triad material demonstrated the lowest transverse strengths of all three materials overall. However, Triad material was unaffected by water storage. The other resins all showed decreased strengths with water storage.
