Thermo-formed (Zendura) Retainer
Zendura material is an engineered polyurethane material that was specifically developed to serve as a clear aligner and retainer treatment material with excellent stress relaxation resistance, strength and toughness.
In 1999 Dr. Ray Stewart, Ph.D., a principle of Bay Materials, worked to engineer a material that was ideal for clear aligner orthodontic treatments. He, in collaboration with a team of material scientists at Bay Materials, succeeded in developing a material that became the benchmark in the clear aligner industry, and has been used broadly for clear aligner treatment since 2000.
In 2004 that material was reformulated for improved clarity and stress retention and was branded as Zendura. Since 2005, Zendura was supplied to several major aligner treatment companies, including ClearCorrect who has been using Zendura material exclusively for its aligner orthodontic systems.
Over the years, orthodontists and dentists have Zendura for use in conventional applications such as retainers, temporary bridges, surgical splints and bleaching trays, etc. Encouraged by the positive feedback and enthusiasm among the customers, Zendura was for direct sale to the public via its website since early 2012.
