A 20-year-old patient was dissatisfied with her discolored composite restorations on her maxillary central incisors and the right lateral incisor. The original restorations had been placed after an accident with traumatic dental injuries approximately five years ago. We went through all available options that would enable us to improve the aesthetics of her anterior teeth and finally opted for replacement of the existing restorations by new direct restorations made of composite resin.

Prior to the restorative procedure, a home bleaching procedure was carried out with Opalescence 10% (Ultradent). In addition, a palatal silicon index was produced to record the shape and morphology of the existing restorations and dentition.

The existing restorations were removed after the administration of local anesthesia. Then, labial and palatal bevels were created, followed by sandblasting of the prepared tooth structure with alumina (50 μm). Hereafter, the enamel was etched for 30 seconds (K-Etchant Syringe, Kuraray Noritake Dental), before the primer and bond of CLEARFIL™ SE BOND (Kuraray Noritake Dental) were used according to the instructions.

Build-up of the palatal walls with a first increment of ‘enamel’ composite (CLEARFIL MAJESTY™ ES-2 Premium A2E, Kuraray Noritake Dental) using the silicon index.

Creation of the mesial and distal marginal ridges in A2E enamel composite. The procedure was facilitated by the vertical placement of sectional matrices (Contact Matrices Stiff Flex Large, Danville) in the interproximal space.

Creation of the dentin core and the dentinal mamelons by placement of an opaque composite increment (CLEARFIL MAJESTY™ ES-2 Premium, A2D). It increases the opacity in the middle third of the restoration.

Filling of the space between the mamelons with translucent composite (CLEARFIL MAJESTY™ ES-2 Premium, Translucent Clear).

Labial finishing of the restorations with a layer of semi-translucent composite (CLEARFIL MAJESTY™ ES-2 Premium, A2E).

Application of glycerin gel on top of the last layer of composite to prevent formation of an oxygen inhibited layer during the final light-curing procedure. Final contouring and polishing were performed by using red (fine) and yellow (x-fine) finishing diamonds followed by high gloss polishing with CLEARFIL™ TWIST DIA (Kuraray Noritake Dental).
