| Outline of Final Research Achievements |
The purpose of this study was to develop a novel non-metal clasp denture (NMCD) material with excellent esthetic and mechanical properties. In this study, a glass fiber-reinforced thermoplastic (GFRTP) made from glass fiber and polypropylene was fabricated using an injection molding, for use in NMCDs. Moreover, their properties such as flexural properties and color stability were assessed. As a result, it was indicated that the GFRTPs with fiber contents of 10 or 20 mass%, and with pigment contents of 2 mass% have acceptable esthetic appearance and sufficient rigidity for NMCDs. Therefore, the fabricated GFRTPs are expected to become attractive materials for NMCDs.
