Clarity Aligners uses a dual-material system with two aligner thicknesses optimized for different tooth movements. Here’s how Flex and Force aligners work.

Flex vs Force Overview

Clarity Flex (0.625mm)

Flex aligners are thinner and more flexible, designed for:

  • Initial tooth alignment
  • Rotational movements
  • Gentle corrections
  • Early treatment stages

The thinner material provides easier seating and increased comfort during initial movements.

Clarity Force (0.75mm)

Force aligners are thicker and more rigid, designed for:

  • Bodily tooth movement
  • Torque applications
  • Complex corrections
  • Final positioning

The thicker material maintains force delivery over time without excessive deformation.

When Each Material Is Used

Your orthodontist determines which material to use based on the tooth movements needed at each treatment stage:

Flex Aligners Typically Used For:

  • Stages 1-8: Initial crowding resolution
  • Rotation movements of canines and incisors
  • Light tipping movements
  • Establishing arch form

Force Aligners Typically Used For:

  • Mid to late treatment stages
  • Closing extraction spaces
  • Root positioning and paralleling
  • Intrusion/extrusion movements
  • Final detailing

Advantages of Dual-Material System

Using two materials provides several benefits:

  • Improved Comfort: Flex aligners are easier to adjust to initially
  • Better Control: Force aligners maintain rigidity for complex movements
  • More Predictable: Matching material to movement type improves accuracy
  • Efficient Treatment: Optimized force delivery may reduce total treatment time

Single-Material Systems

Most clear aligner systems use a single material thickness throughout treatment. Clarity’s dual-material approach allows orthodontists to select the optimal material for each specific movement.

Care Instructions

Both Flex and Force aligners require the same care:

  • Wear 20-22 hours per day
  • Remove for eating and drinking (except water)
  • Rinse with cool water and brush gently
  • Store in case when not wearing
  • Avoid hot water (can warp material)
