This position paper reviews physical and mechanical properties of thermoplastic resin used for non-metal clasp dentures, and describes feature of each thermoplastic resin in clinical application of non-metal clasp dentures and complications based on clinical experience of expert panels. Since products of thermoplastic resin have great variability in physical and mechanical properties, clinicians should utilize them with careful consideration of the specific properties of each product. In general, thermoplastic resin has lower color-stability and higher risk for fracture than polymethyl methacrylate. Additionally, the surface of thermoplastic resin becomes roughened more easily than polymethyl methacrylate. Studies related to material properties of thermoplastic resin, treatment efficacy and follow-up are insufficient to provide definitive conclusions at this time. Therefore, this position paper should be revised based on future studies and a clinical guideline should be provided.
本立场文件回顾了用于非金属卡环义齿的热塑性树脂的物理和机械性能，并根据专家小组的临床经验，描述了每种热塑性树脂在非金属卡环义齿临床应用中的特点及并发症。由于热塑性树脂产品在物理和机械性能方面存在很大差异，临床医生在使用时应仔细考虑每种产品的具体性能。一般来说，热塑性树脂比聚甲基丙烯酸甲酯具有更低的颜色稳定性和更高的断裂风险。此外，热塑性树脂的表面比聚甲基丙烯酸甲酯更容易变得粗糙。目前，关于热塑性树脂材料性能、治疗效果和随访的研究不足以得出明确结论。因此，本立场文件应根据未来的研究进行修订，并应提供临床指南。
