Antreior Single Tooth Restoration for Esthetics

It is difficult to make an artificial central incisor similar to natural tooth. All ceramic porcelain of this patient is not esthetic, and there is gingival recession due to ill-fitted margin. She has class II division 1 occlusion, so upper central incisors is labioversed. Upper light central incisor is well-characterized but the yellowish brown color of dentin is appeared on the incisal third portion of the central incisor. At 1st trial, the shape and characterization of restoration is good but shade is little dark. At 2nd trial, the shape is better but patient complained on black triangle of mid interdental space, so mesiocervical portion of restoration is overcontoured to compromise the black triangle. Completed metal ceramic crown is in harmony with the adjacent central incisor in aspect of shape, shade, and characterization.
