About Bioclear Matrix

Bioclear was founded in 2007 by dentist and inventor Dr. David Clark with the vision of creating a modern, patient centered approach for restorative dentistry. The Bioclear Method is a cutting-edge technique for non-invasive anterior and posterior composite restorations, including an innovative approach to black triangle closures. With Dr. Clark’s updated tooth preparation, injection molding technique, and patented, clear anatomic matrix system, doctors can reliably achieve stronger, longer lasting, and aesthetically superior composite restorations. Bioclear offers a variety of education opportunities to help dentists and their practices transition to modern composite dentistry, including interactive, hands-on courses at the state-of-the-art Bioclear Learning Center in Tacoma, WA.
