Technique for making a customized shade guide

A technique has been presented for making a custom shade guide that provides a direct visual means for conveying color information to the laboratory technician. The technique consists of applying pigment directly to acrylic resin denture teeth using colored drawing pencils. This technique was originated by Dr. Royal Norman of Omaha, Nebraska. One of the authors (S. W. A.) first saw Dr. Norman present it to the USAF Area Dental Laboratory Workshop, Westover AFB, Mass., in 1969.
