Our Story

In 1999, when Frank Madrigal was working as a dental assistant, he noticed a lack of expertise, service, and quality in the dental appliance industry. He envisioned creating the most hassle-free laboratory for clinicians offering modern high-tech fabrication and old-fashioned customer service. In that moment, True Function found its humble beginnings.

What started as a small dental lab operating out of a dentist’s office has grown to become a leading fabricator of dental appliances for the treatment of OSA, TMJ splints, and Occlusal guards. True Function has and will always be committed to providing its clients with peace of mind to their patients with a device that is true to fit and function.

We are a family-owned and operated business. The True Function community of technicians are highly skilled artisans with a combined 120+ years of experience fabricating dental appliances.
