 STATEMENT OF PROBLEM: Studies on the mechanical properties of 3-dimensionally (3D) printed denture base polymers with appropriate test methods are lacking. PURPOSE: The purpose of this in vitro study was to determine the flexural strength (σ MATERIAL AND METHODS: Three resins for additive (Lucitone Digital Print, LDP
  Flexcera Base, FCB and an experimental material, EXP) and 1 for injection molding (IvoBase Hybrid, IBH) fabrication were analyzed. Standardized specimens were fabricated, polished, tempered, and thermal cycled (5 °C to 55 °C) before testing for σ RESULTS: The σf, E, and HM of 3D printed polymers were significantly lower than those of the injection molded, both for the tempered and aged groups. The σf was lowest for FCB and highest for IBH in the tempered state. The K CONCLUSIONS: The σ
