Maxflex Clear Aligner & Retainer Sheets
Thermoforming sheet material for clear aligners, retainers & night guards
Maxflex thermoforming sheets are the raw material dental labs and aligner manufacturers use to fabricate clear aligners, retainers, night guards, and attachment templates. Each sheet is a precision-engineered disc designed to be heated and pressure-formed over a dental model. The range spans two material families — the monolayer MAX series and the multi-layer FLEX series — so labs can match sheet performance to the demands of each case.
Choose your material
Two sheet series, one selection guide
Maxflex sheets come in two construction types. The monolayer MAX series is built for strong, predictable force; the multi-layer FLEX series trades a little of that force for comfort and exceptional crack resistance.
Monolayer sheets
A classic single-layer sheet built for strong, predictable tooth movement. Available in a TPU grade (MAX Standard) for the highest initial force, and a heat-resistant copolyester grade (MAX Premium) that trades a little force for outstanding dimensional stability and easy trimming.
- High initial force for efficient tooth movement
- Excellent clarity and stain resistance
- Dependable crack and abrasion resistance
- For aligners, retainers, and attachment templates
Multi-layer sheets
A composite sheet with rigid outer layers bonded to an elastic inner core. The result is a gentle, continuous force that stays comfortable to wear, plus far greater resistance to cracking — Maxflex measures roughly ten times the bending cycles before breakage compared with a leading competitor.
- Gentle, continuous force for patient comfort
- Around 10× the bending cycles before breakage
- Resists delamination; holds clarity and stain resistance
- For aligners, retainers, and night guards
Inside a FLEX sheet
A tri-layer structure
FLEX sheets are built from three bonded layers. Hard outer skins do the structural work; a soft elastic core does the comfort work.
Outer layers — hard material
The two rigid outer skins give the sheet stable, sustained corrective force and resist heat, staining, and moisture — so the appliance keeps its shape and its clarity through everyday use.
Inner layer — elastic core
The soft elastic core makes the sheet comfortable against the teeth, improves the torquing force applied during treatment, and allows easy insertion and removal — which also reduces wear on bonded attachments.
What you can make
Applications
One material family covers the core of a clear-aligner lab's output.
Clear aligners
Near-invisible aligners formed sequentially to move teeth.
Retainers
Post-treatment retainers that hold the corrected position.
Night guards
Thicker FLEX Dual Premium sheets for occlusal protection.
Attachment templates
Thin sheets for placing composite attachments accurately.
Why it performs
Tested performance characteristics
Maxflex publishes laboratory testing across the range. The headline findings:
Gentle, comfortable force
FLEX delivers the softest initial force in the range, easing the strain of putting aligners in and taking them out.
Strong force retention
FLEX Premium and MAX Premium hold their corrective force steadily through the day rather than dropping off quickly.
Heat resistance
Premium-grade sheets keep their shape far better than standard TPU when exposed to hot drinks, protecting the fit.
Stain resistance
Every grade resists discoloration from coffee, tea, red wine, and cola in extended soak testing.
Resilience
FLEX Premium springs back fully and quickly after repeated twisting and flexing.
Durability
The multi-layer FLEX construction resists cracking many times longer than conventional single-layer sheets.
