Where your current aligner setup
falls short
When you rely on a big brand
You pay for their margin
Pricing only improves when you commit to volume. Without minimums, you pay the top rate. Every time.
Their workflow, not yours
You can't change how cases are reviewed or approved. Clinical decisions run through their system, on their terms.
A closed ecosystem
Proprietary software and locked workflows leave no room to adapt to how your practice actually operates.
When you MANUFACTURE IN-HOUSE
Equipment runs your schedule
Printers fail, thermoforming machines break, resin runs out. Maintenance and calibration become part of the clinical week.
Quality varies case to case
Manual trimming and machine variability mean that no two trays are guaranteed to be identical. Industrial consistency is hard to replicate in-clinic.
You become the manufacturer
Printing, washing, trimming, and bagging. Every hour spent there is an hour not spent on patients.

​
Different cases, different needs. You decide on each one.
The Rise of Orthopreneur
Some orthodontists stopped renting someone else's infrastructure. They built their own brand, on their terms.
These are two of them.
