A word from
our CEO

The future of orthodontics is great and we are determined to play a key role in it. K Line provides its services through two distinctive business models. 
The first is OEM, where we enable our clients to build their own unique aligner brand. 
We support not only in manufacturing, shipping, and logistics, but also offer consulting in marketing and branding. 

K Line’s second business model is our flagship product: ClearX. The shape-shifting ClearX aligners are based on 4D orthodontics which is a fundamental innovation for the whole industry, unlocking so many new possibilities. More accurate, faster, eco-friendly, and smart are all significant advantages 4D tech brings to orthodontics.
