Orthodontic material IPN Film

Revolutionary clear aligner material for ideal orthodontic biomechanical expression Self-developed Dental Material The first TPU film granted the certificate for dental use by NMPA in China​​​​​​ According to the application needs of clear aligner and the biomechanical needs of orthodontic treatment, through rigorous selection of raw materials, creative adjustment of the proportion of components, and optimization of processing technics, we successfully developed the IPN (Interpenetrating Polymer Network) film, whose hardness/softness is adaptive to various cases. 3-Layer Structure By using polymer science, the 3-layer solution reaches the balance between the resilience needed for easy insertion and take-off and the rigidity needed for force persistence and durability. Different properties of each layer ensure the ideal force expression required by orthodontic treatment. More durable and stable Slow stress relaxation after elastic deformation makes IPN film more durable. Stronger tear resistance After forming, it is much more difficult for aligners to tear. Better fitting The real curvature detection ensures accurate fitting to various tooth shape.
