Abstract
in English, Chinese

Aesthetic and comfortable transparent retainers and clear plastic appliances are becoming increasingly popular, and their components, especially thermoplastic materials, are gradually attracting widespread interest. Orthodontic thermoplastic materials are versatile polymers, and thus their properties, such as force delivery, force relaxation, and aging properties have been comprehensively studied. Meanwhile, blending modification technology has been applied for the acquisition of novel materials with enhanced characteristics. In this paper, we review the types and properties of thermoplastic materials, the development process they undergo, factors that influence their properties, and some development prospects.

美观舒适的透明保持器及隐形矫治器越来越受到患者们的欢迎，而其主要制作材料热压膜材料也逐渐受到了学者们的关注。正畸用热压膜材料主要是一类性能各异的聚合物，诸多学者研究了不同种类热压膜材料的不同性能，包括其应力释放、应力松弛、老化等。同时为了获得拥有更优秀性能的材料，共混改性等方法也用于材料的研究中。本文将就热压膜材料的种类、性能及影响因素和发展展望作一综述。.

Keywords: aging; force delivery; force relaxation; modification; thermoplastic material; water absorbing; wear resistance.
