<P>PROBLEM TO BE SOLVED: To solve such problems that manufacturing a final crown for a patient typically requires a length of time of between one and three weeks, the patient needs to wear a provisional restoration in order to protect the existing exposed dentition and to maintain the health and integrity of the gingival areas, and that in many instances, the dentist will fabricate a provisional crown directly chair-side, and this procedure can take a significant amount of chair time and as a result be quite costly. <P>SOLUTION: A kit for producing a dental restoration is provided that comprises: at least one pre-shaped dental crown made from a plastically deformable dental composite material curable by light; a container impermeable to light, in which the pre-shaped dental crown is kept before it is applied to a tooth stump; and optionally a film which covers the outer surface of the pre-shaped dental crown. <P>COPYRIGHT: (C)2008,JPO&INPIT |
