- Controlled, Not Just Aligned: Precision Tooth Movement with Shape Memory Aligners
Clear aligners are increasingly capable of complex tooth movement, yet certain movements — including translation and root torque — remain classified as having low predictability. This lecture reframes that assumption through biomechanics.
Shape memory aligners deliver light, continuous forces within the physiological range — fundamentally different from the high, rapidly decaying forces generated by thermoformed aligners. The key to precision lies not in the attachment, but in the fit: the accuracy of surface adaptation becomes the accuracy of tooth movement.
Through a series of clinical cases — including translation and root control in both growing and adult patients — this lecture explores the potential of shape memory aligners to expand the boundaries of predictable tooth movement.
