Zahn Dental and the NADL continue to share a mutual mission and vision for evolving the voice of the laboratory industry.

The National Association of Dental Laboratories (NADL) is a federation of state commercial dental laboratory associations formed in 1951 in Chicago by a merger of the Dental Laboratory Institute of America and the American Dental Laboratory Association. In 1952, NADL opened its national headquarters offices in Washington, D.C. From 1968 to 1971, the organization was known as the National Association of Certified Dental Laboratories. The association changed back to its original name in 1971.

In 2001, the National Association of Dental Laboratories moved its headquarters office to Tallahassee, Florida. The NADL Mission: The National Association of Dental Laboratories is the unified voice of the dental laboratory industry supporting dentistry and serving the public interest by promoting high standards. NADL accomplishes this by providing programs, services, and networking opportunities to meet the evolving technical, educational, professional, and business needs of dental laboratories.

The NADL Vision: The National Association of Dental Laboratories shall be the pre-eminent voice for the dental laboratory industry to ensure professionalism through strategic leadership, partnering, and cohesive representation before regulatory and educational entities. NADL shall guide the industry by setting standards and providing a venue for members to advance in the field of dental technology.
