The Zendura Story

Zendura material is based on a superior polymer chemistry, developed specifically to advance clear aligner therapy.

In 1999, Dr. Ray Stewart Ph.D. and a team of material scientists at Bay Materials were tasked with formulating the ideal material for clear aligner orthodontic treatment. Rather than starting with available dental resins, the team worked backwards from requirements that best move teeth; specifications of high toughness, clarity, and excellent stress retention.

The team succeeded in developing a new material that targeted those specifications and became a benchmark in the clear aligner industry. This material was used for clear aligner treatment starting in early 2000.

The story of Zendura does not end there, however. The Bay Materials team saw room for improvement, and in 2004 began a new development project. This effort yielded targeted improvements in stress retention, crack and stain resistance, and optical clarity. This improved material was branded Zendura, and a limited supply was sold to several major aligner treatment companies, including ClearCorrect, who has been using Zendura material exclusively for its aligner orthodontic systems.

Over time orthodontists and dentists requested Zendura for use in conventional applications such as retainers, temporary bridges, surgical splints and bleaching trays. Encouraged by the interest and enthusiasm, Bay Materials has offered Zendura for direct purchase since early 2012.
