Reach out to learn more about what SureSmile® Adaptive Trimlines can do for you.
Adaptive Trimline
Trimlines are powerful tools that allow you to adapt your aligner's trimline for treatment goals such as rotation, isolated extrusion, treatment time, or aesthetics. Trimline type and height impact the forces for optimal movements, depending on your goals. With SureSmile's Adaptive trimline, you can customize and control how to apply the trimline type between scalloped and straight and height by aligner arch within each stage while planning your parents' treatment.
Why it matters
Suggested applications on how to apply the best trimline per stage:
1. 0mm Straight Trim - suitable for most cases, balances flexibility and stiffness
2. 2mm Straight Trim – deep bite correction, bodily movements, arch expansion, torque expression
3. Scalloped Trim – Severe crowding, isolated extrusions and rotations, recession and larger undercuts on tooth anatomy, or excessive spacing
