The protocol, up close

What is inside a Sorridi aligner

Two aligners for every phase, different materials for Soft and Hard, a straight edge that reaches past the gum line and no attachments.

01Double aligner

Two aligners for every phase

Every treatment phase uses two aligners: first the Soft one, then the Hard one. The virtual set-up selects the thickness according to the movement required, so the force builds up gradually instead of arriving all at once.

  • 1st aligner: Soft. 2nd aligner: Hard.
  • More gradual forces than single-aligner systems.
  • Less material fatigue during the phase.

02Materials

Soft: one layer. Hard: three layers.

Soft and Hard differ in structure as well as thickness. The Soft aligner is a single layer of PET-G. The Hard aligner has three layers: PET-G on the outside and a TPU (polyurethane) core in the middle.

03Straight edge

A higher edge, past the gum line

The edge does not follow the scalloped outline of the teeth: it is straight and reaches past the gum line. With more surface to rest on, the aligner spreads the forces evenly over the whole arch.

  • Straight margin, not scalloped.
  • Greater extension past the gum line.

04No attachments

Zero attachments, even for complex movements

It is the greater extension that makes attachments unnecessary, even for complex movements such as intrusions and extrusions. No bonding and rebonding: less chair time and fewer appointments.

  • Customisable pressure points to optimise the biomechanics.
  • Lower risk of errors related to operator positioning.

05Laser-Tech finish

Finished with a cut of very high precision

Laser cutting leaves a precise, clean edge, minimising the risk of irritation and injury to the oral mucosa. The result is a more comfortable and better-looking aligner.

06Incremental force

Phase after phase, Soft then Hard

With every phase the teeth move closer to the position planned in the 3D simulation. Periodic photo checks follow the progress of the therapy, for more predictable treatments with fewer refinements.
