--Difference between TPU and PETG
1.Compared with traditional PETG, material of TPU manifests superior performance in several aspects such as wearing comfortability, tensile strength, durability, and stress retention ratio, etc.
2.The TPU becomes more popular, specially the 3 layers TPU sheet, which has high bending resistance and stress retention, then get best the Orthodontic effect in 3-6 months. Delivering up to 150%-plus better teeth movement force than competing materials over a 7-10 day wear period. That's why now TPU 3 layers becomes more and more popular. We have the hard-soft-hard sheet (same with Zendura )and soft-hard-soft( same with Invisalign) 2 models, but only 2/5 price to them.
--TPU 3 layers advantage
1.The stiffness and elasticity of our dental coping sheet are adjustable according to different hardness material selection and structure design. It shows the balanced benefits of comfortability, stress retention, heat resistance, stain resistance and crack resistance.
2.The outermost shell provides abrasion resistance, acting as a tough barrier to grinding or bruxing forces of the teeth. The inner shell is tough and grips the teeth firmly to exert a firm and sustained force on the teeth and move them in a precisely controlled manner. Sandwiched between the outer and inner shells, lies the central elastomeric layer which provides elasticity to the entire structure.
