About Zendura Dental#
Transforming smiles through advanced materials science.
For over two decades, Zendura Dental has set the benchmark for high-performance thermoplastic materials used in clear aligner and retainer fabrication — engineered by polymer scientists, trusted by clinicians, and chosen by aligner manufacturers worldwide.
Our Story#
Built on polymer chemistry, born in Silicon Valley.
Zendura Dental is the brand of Bay Materials, LLC — a polymer research and development company founded in 2000 by Dr. Ray Stewart and headquartered in Fremont, California. From day one, our purpose has been singular: to engineer thermoplastic materials that raise the standard of clear aligner therapy for clinicians, manufacturers, and the patients they serve.
Today, as a member of the Straumann Group, we serve as the group’s Center of Excellence for the development, manufacturing, and marketing of advanced thermoplastic materials for orthodontic and dental applications — combining Silicon Valley materials-science depth with global reach.

Our Science#
R&D is the engine behind every Zendura material.
With over 30 years of expertise in polymer chemistry applied to clear aligner and retainer therapy, our R&D group custom-designs every Zendura material from the molecular level up — engineering the specific mechanical properties, optical clarity, and patient-wear characteristics demanded by modern orthodontic treatment.
Custom polymer design#
Every Zendura material is engineered from the molecular level for a specific clinical application — balancing force, comfort, clarity, and durability rather than compromising between them.
Patented innovations#
Our portfolio is protected by multiple US patents covering proprietary thermoplastic constructions, including the dual-shell architecture that powers our flagship Zendura FLX aligner material.
30+ years of expertise#
Our materials scientists bring decades of combined experience in polymer chemistry and orthodontic applications — a depth of knowledge that few companies in dental thermoplastics can match.
At the forefront of innovation#
From the first medical-grade polyurethane retainer material to the industry’s first dual-shell aligner construction, Zendura has consistently led the way in advanced thermoplastic development.

Quality & Standards#
Engineered to medical-grade standards.
From raw resin to finished sheet, every Zendura material is developed and produced to the standards our customers — and their patients — expect from a medical device material.
Medical-grade polyurethane#
Our flagship materials are formulated from a proprietary, medical-grade thermoplastic polyurethane (TPU) resin developed specifically for orthodontic applications.
BPA, phthalate, gluten & latex free#
Our materials are formulated to be free from BPA, phthalates, gluten, and latex — giving clinicians confidence for every patient, including those with sensitivities.
Patented thermoplastic technology#
Our Dual Shell Dental Appliance and Material Constructions family is protected by multiple US patents — proof of an R&D investment that goes far beyond off-the-shelf chemistry.
Manufactured in California, USA#
Every sheet is produced at our Fremont, California facility — keeping development, testing, and manufacturing under one roof for end-to-end quality control.
