Abstract

Shape memory polymers (SMPs) have been intensively investigated for multiple medical applications in recent years. In our lab, we have developed several SMPs with tailored transition temperatures, excellent shape fixing and shape recovery, and variable stiffness, with values ranging from > 1 GPa (hard) to < 1 MPa (soft). Recently, we have endeavored to apply two particular SMPs, a castable shape memory polymer (CSMP) and a shape memory rubber, to orthodontic appliances. We have measured the mechanical properties, water absorption, stain resistance, and stress stability and compared the results with currently used orthodontic polymers, revealing significant advantages. Prototype appliances are presently under evaluation. In this presentation, we will introduce the progress we have achieved and propose how SMPs can offer unique functionality to orthodontic appliances.
