Abstract: An anterior tooth characterization guide includes several sets of anterior tooth samples which each have differing characteristics. The characterization guide is useful in connection with a method for selecting characterizations for an anterior tooth prosthesis and a process for fabricating a characterized tooth prosthesis, which permit a dentist to relay to a laboratory an accurate representation of the tooth prosthesis to be manufactured. In this regard, the characterization guide is utilized to select a dentin color for the tooth prosthesis from several tooth samples in which the incisal color is constant. The body to incisal relation for the tooth prosthesis may also be selected from tooth samples in which the dentin is constant, and the amount of white stain for the tooth prosthesis may be selected from the tooth samples in which the dentin and enamel are constant.

Abstract: A system for color matching a dental prosthesis is provided. The system includes a shade guide or color range finder comprising a plurality of color elements, each of which identifies a different color than the remaining elements. This system also includes a plurality of plastic shells that are configured for placement on or along side a patient's anterior or posterior tooth that has previously been prepared for receiving a dental prosthesis. The shells correspond in color to the colors of the color range finder elements. The system further includes some type of coloring for selectively modifying the aesthetic appearance of a shell so that the dental practitioner can prepare an accurate representation of what is to be produced as a dental prosthesis in the laboratory.

Abstract: A posterior tooth shade guide includes a plurality of posterior tooth samples each positionable upon a posterior tooth holder and bearing differing tooth characteristics. Several of the tooth samples have differing white stain characteristics, others have differing brown stain characteristics, and still others have differing incisal layer colors. Another set have differing percentages of the incisal that covers the body of the tooth prosthesis. A selector ring is provided to permit the selection of a specific brown stain color. Utilizing the posterior tooth shade guide, a dentist and the laboratory may utilize a method for selecting characterizations of a tooth prosthesis wherein the posterior tooth samples are utilized to select: brown stain characteristics, white stain characteristics, incisal layer color, and the percentage of the incisal that covers the body of the tooth prosthesis.

Abstract: A winged dental bridge includes a flexible bridge framework which is attachable to two abutment teeth, and a relatively hard veneer for placement over an exposed labial surface of the bridge framework. The bridge framework includes a pontic, a first wing extending laterally outwardly therefrom for attachment to a first abutment tooth, and a second wing for attachment to a second abutment tooth. The bridge framework is formed of a laminated resinous composite material including an etchable material which forms the labial surface of the pontic and attachment surfaces of the wings, and a polishable material which entirely covers the lingual surface of the etchable material. In a method for making the winged dental bridge, the uncured resinous composite structure is applied over a separator to a cast taken of the patient's mouth. The uncured bridge framework is light cured on the bridge in a pressurized nitrogen gas environment, and subsequently heat and light cured.
