THE CONVERSATION
Webinar
Description
Join LuxCreo and Dr. Kelvin Chang, DDS, MS for an in-depth exploration of the science behind clear aligner deformation, 4D Smart Materials, and the design flexibility enabled by direct-print aligners.
Clear aligner therapy is evolving beyond traditional thermoformed workflows. As direct-print technology introduces new materials and greater control over aligner geometry, clinicians have new opportunities to understand, and intentionally engineer, the forces that drive tooth movement.
Through a combination of foundational concepts, material science, real clinical cases, and innovative special designs, this webinar will explore how understanding deformation and material behavior can help clinicians think differently about aligner design and treatment.
FROM MATERIAL SCIENCE TO ALIGNER DESIGN
What You’ll Learn.
Decoding Clear Aligner Treatment
Understanding the 5 Types of Deformation
Understand how bending, compression, tension, shear, and torsion shape force delivery during clear aligner treatment. Learn how these deformation modes—and the viscoelastic behavior of polymers—can influence force consistency, treatment efficiency, and control of tooth movement.
4D Smart Material
Resin-based Photocurable Polymer
Explore the material science behind LuxCreo’s DCA resin, including its high glass transition temperature, stress relaxation, and ActiveMemory™ behavior. Discover how ActiveMemory™ helps the aligner recover toward its designed shape, supporting more consistent force delivery throughout treatment.
Direct-Print-Aligner Design Flexibility
Geometry-engineered Aligner
Discover how direct printing expands aligner design beyond the limitations of traditional thermoforming. Geometry-engineered features can be built directly into the aligner to intentionally influence force application, enabling greater flexibility and control in tooth movement.
