Abstract
Abstract A one-piece dental wedge comprised of a rigid core and an elastic outer component. Both the core and the outer component are comprised of biocompatible materials. The core may be comprised of a plastic, like a polymethyl methacrylate resin, wood, metal, or the like. The elastic outer component is comprised of an elastomer of either the gel or non-gel type.
