Abstract
En 中文
• SMP aligners introduce thermomechanical force modulation in orthodontics • Their behavior is governed by glass transition temperature and segmental mobility • Force delivery results from entropy-driven recovery and viscoelastic relaxation • SMP aligners differ fundamentally from thermoformed aligners and NiTi wires • Future developments include 4D printing and adaptive polymer design
