本研究的目的是比较用于非金属卡扣义齿的热塑性丙烯酸树脂与热塑性聚酰胺和传统热聚合义齿基托树脂的颜色稳定性、吸水性和细胞毒性。本研究使用三种类型的义齿基托树脂，即传统热聚合丙烯酸树脂（Paladent 20）、热塑性聚酰胺树脂（Bio Tone）、热塑性丙烯酸树脂（Acrytone）。制作了一百五个样本。对于颜色稳定性测试，将样品浸入咖啡色 T 恤和绿色 T 恤中 1 周和 8 周。通过光谱仪测量颜色变化。在水中浸泡 1 周和 8 周后测试吸水性。为了测试细胞毒性，测量细胞活力并通过FE-SEM分析细胞附着。所有类型的义齿基托树脂在浸泡 1 周和 8 周后都会出现颜色变化。然而，义齿基托树脂之间没有显着差异。所有样品中咖啡色 T 恤的颜色变化都比绿 T 恤显着。在吸水性测试中，热塑性丙烯酸树脂的值低于传统的热聚合丙烯酸树脂和热塑性聚酰胺树脂。三种类型的义齿基托在细胞活力测定中显示出较低的细胞毒性。热塑性丙烯酸树脂表现出类似的细胞附着力，但比传统的热聚合丙烯酸树脂附着更稳定。用于非金属卡扣义齿的热塑性丙烯酸树脂表现出可接受的颜色稳定性、吸水性和细胞毒性。为了验证在口腔中的长期稳定性，需要进行额外的体外研究。
The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic polyamide resin (Bio Tone), thermoplastic acrylic resin (Acrytone) were used as materials for this study. One hundred five specimens were fabricated. For the color stability test, specimens were immersed in the coffee and green tee for 1 and 8 weeks. Color change was measured by spectrometer. Water sorption was tested after 1 and 8 weeks immersion in the water. For the test of cytotoxicity, cell viability assay was measured and cell attachment was analyzed by FE-SEM. All types of denture base resin showed color changes after 1 and 8 weeks immersion. However, there was no significant difference between denture base resins. All specimens showed significant color changes in the coffee than green tee. In water sorption test, thermoplastic acrylic resin showed lower values than conventional heat-polymerized acrylic resin and thermoplastic polyamide resin. Three types of denture base showed low cytotoxicity in cell viability assay. Thermoplastic acrylic resin showed the similar cell attachment but more stable attachment than conventional heat-polymerized acrylic resin. Thermoplastic acrylic resin for the non-metal clasp denture showed acceptable color stability, water sorption and cytotoxicity. To verify the long stability in the mouth, additional in vitro studies are needed.
