4ADENT DURA Series Clear Aligner Material is made of PETG and TPU (Multi-Layer) medical-grade material. Orthodontists and aligner manufacturers have long preferred multi-layer structures due to their customization, precision, and versatility, Multiple layers allow for the customization of material properties, combining flexibility and rigidity where needed, Different layers can also be designed to provide optimal force and precision for tooth movement. This versatility allows aligners to be customized to the patient’s specific needs and treatment plan.
Force Decay
E.g. : Clear series
Under simulated oral temperature and controlled environmental conditions, a specific force is applied to the orthodontic appliance to induce a certain amount of elongation. The change in force is recorded after 24 hours of maintaining a constant elongation. The ratio of force reduction represents the force decay rate.Lower force decay rates indicate greater force stability.
4Adent Clear, along with the other two multilayer sheet series – Flex & Dura, offers an additional level of comfort during orthodontic treatment by combining orthodontic strength with comfort.These two dental sheets, made of composite materials, possess good softness and elasticity,making them more resistant to deformation and capable of providing adequate orthodontic force. The original shape can be restored after the aligner is removed, ensuring the effectiveness of orthodontic treatment.
In the video, we can see that the process engineer uses a dental mold to apply high-temperature pressure film to create a transparent orthodontic plate for teeth.
