Clarity Aligners Flex + Force enables orthodontists to pick from two aligner materials in one treatment design. The aligners can be used with the company's cloud-based software Oral Care Portal, which features an advanced treatment design tool.

Clarity Aligners Flex + Force is made of a five-layer mix of materials, which helps it resist staining and scratching and offers heightened flexibility and resilience, the company said.
