CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to Ser. No. 10/349,460, filed Jan. 22, 2003, entitled "Dental Prosthesis Fabrication and Placement System and Associated Methods," the contents of which are incorporated hereinto by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to systems and methods for performing a dental procedure, and, more particularly, to such systems and methods forfabricating and placing a dental crown or bridge. [0004] 2. Description of Related Art [0005] The fabrication and placement of dental prostheses such as crowns and bridges typically requires at least two visits to the dentist's office to complete. At the first visit, the placement site in the patient's mouth is prepared, and a mold is made from which a permanent prosthesis is to be constructed. A temporary prosthesis is inserted into the site, awaiting the fabrication of the permanent device, which is usually performed at a remote location from the dentist's office. At a second visit, the permanent prosthesis is affixed into the site. SUMMARY OF THE INVENTION [0006] The present invention is directed to a dental prosthesis fabrication and placement system and associated methods that can be completed in one visit. The dental prosthesis, which may comprise, for example, a crown or short-span bridge, is a prefabricated composite shell that is modified by the addition of composite material and cured on-site to form a custom-modified device. [0007] The method of the invention, which is for fabricating and placing a dental prosthesis, comprises the steps of placing a prefabricated prosthesis shell over a tooth that has a surface that has been prepared for prosthesis placement and trimming the shell to achieve desired seating on the tooth and optimal occlusion. The shell is then removed from the tooth, and the tooth's prepared surface is painted with a separating medium. An interior surface of the shell is painted with a bonding agent, and an uncured composite material is added to the shell's interior space. [0008] Next the shell is positioned over the tooth, and the composite material is partially light cured in situ. The shell is removed from the tooth and modified as desired to achieve optimal conformation. Any added composite is then fully light cured, and the shell is affixed to the tooth. [0009] The features that characterize the invention, both as to organization and method of operation, together with further objects and advantages thereof, will be better understood from the following description used in conjunction with the accompanying drawing. It is to be expressly understood that the drawing is for the purpose of illustration and description and is not intended as a definition of the limits of the invention. These and other objects attained, and advantages offered, by the present invention will become more fully apparent as the description that now follows is read in conjunction with the accompanying drawing. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a side view of a model of the patient's mouth. [0011] FIG. 2 is a side view of the model with the respective tooth prepared. [0012] FIG. 3 is a side view of the model with a shell crown placed therein. [0013] FIGS. 4A-4C are views of the shell crown: FIG. 4A, a side view; FIG. 4B, an occlusal view; and FIG. 4C, an internal view. [0014] FIG. 5 is a side view of the mouth with the tooth to be crowned prepared. [0015] FIG. 6 is a side view of the shell crown placed over the prepared tooth. [0016] FIG. 7 is a side view of the shell crown having added material. [0017] FIG. 8 is a side view of the finished crown bonded to the tooth. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0018] A description of the preferred embodiments of the present invention will now be presented with reference to FIGS. 1-8. [0019] The method of the present invention in a preferred embodiment comprises the steps of making a study model 10 of the patient's mouth (FIG. 1), comprising, for example, stone. This may be accomplished at an appointment prior to the prosthesis-placement appointment. Additional information that should be gathered include bite registrations and shade data. Using the study model 10 and additional information, the selected tooth 11 (or teeth) is prepared on the model in advance (FIG. 2) for fitting a custom shell restoration 12 thereto. The custom shell restoration 12 should be prepared to accurately reflect parameters such as color, as well as conformational parameters such as occlusion, proper contours, estimated gingival finish line, and interproximal contacts (FIGS. 3 and 4A-4C), and has in a preferred embodiment a minimum thickness of 0.3 mm and a preferred thickness of 1.0-1.5 mm.
