Why choose us
Every movement starts with people.
Behind every aligner we manufacture is a team of innovators, engineers, orthodontists, and visionaries who believe in one mission: to transform orthodontics by making world-class aligner solutions accessible, scalable, and trusted worldwide.
From our very first aligner produced to becoming the world’s largest private-label manufacturer of clear aligners, our journey has always been defined by bold ideas and relentless execution.
Each milestone — new facilities, advanced technologies, global partnerships — reflects not just growth, but a deeper commitment to empowering the brands and clinics we serve.
What sets K Line apart is the strength of our people and the partnerships we build. Collaboration drives everything we do — with our clients, our teams, and the industry.
Together, we’re not just building aligners.
We’re shaping the future of smiles.

A word from our CEO
The future of orthodontics has never looked brighter — and K Line is determined to lead the way.
We began our journey by creating our own aligner brand. But as the market evolved, so did our vision. We understood that our greatest impact would not come from building a single brand, but from enabling hundreds of them. By shifting our focus to private label, we opened the door for doctors, entrepreneurs, and DSOs worldwide to create aligner brands backed by world-class manufacturing, technology, and expertise.
Today, K Line is the world’s largest private-label clear aligner manufacturer — producing millions of aligners each year, supported by advanced orthodontic studies, innovative treatment planning, and cutting-edge technology.
I believe the next era of orthodontics will be defined by collaboration. The strongest brands will be those that own their identity, their patients, and their growth — while partnering with us for the scale, innovation, and global reach to make it possible.
At K Line, we are proud to be the engine powering this future.
