(a) Stone model of maxillary anterior teeth. (b) The stone model was waxed-up to establish a harmonious length and shape of the anterior teeth. The patient was very happy with this blueprint of her teeth. (c) A matrix made of putty-consistency VPS (vinylpolysiloxane) impression material was prepared from the waxed-up model. This silicone index was used as guidance for the lingual contour and to establish the new incisal edge position

(a) A mock-up was made with bis-acryl composite (Protemp 4 (also known as Protemp Plus), 3M ESPE) to allow the patient to foresee the esthetic outcome of the new restorations. (b) Diagnostic resin-based composite restorations were made prior to the adhesive procedure, to verify the stratification and thickness of each composite layer and the color.
