While classical cavity preparation design works well for amalgam, it may not suit composite, as composite resins have a lower diametral tensile strength. This observation led to the development of the Bioclear method, which alters cavity preparations using engineering principles and modern dental materials. Instead of filling a hole, a monolithic shrink wrap of composite resin is created around the tooth, resulting in a compression joint instead of a tension joint at the tooth/ composite interface. The tooth is repaired rather than restored, using a repeatable method that combines the simplicity and economic advantages of direct composite restorations with high aesthetics and strength.

In Janurary, 2019 3M entered into a partnership with Bioclear Matrix founded in 2007 by Dr David Clark. The company develops and markets matrix systems and techniques that support a modern approach to restorative dentistry. We talked to the inventor and dentist Dr David Clark about his motivation to develop the Bioclear method, and about the basic principles and advantages of this technique.
