A tight proximal contact will balance the mesial and distal forces and prevent food impaction. For a while now, the use of preformed matrices and separator rings, in combination with wedges, has made it possible to obtain good restorations with satisfactory morphology. An even more efficient system has recently been introduced, which combines preformed matrices, innovatively designed wedges, and nickel-titanium rings providing optimum separation that remains consistent over time. This clinical case demonstrates the procedure for conservative restoration of teeth 15 and 14 using this innovative system. The radiograph (Figure 1) shows that the patient has a distal carious lesion of 14 and a mesial lesion of 15 (Figure 2). After isolatin...

This kind of pathology leads to the whitish, opaque, unpleasant appearance of enamel which is often visible at speaking distance. Proposed treatments, depending on fluorosis severity, range from expensive ceramic veneers to free hand bonding restorations and abrasive chemical treatments. (S.Ardu et al, 2009) Bleaching is considered before porcelain veneer placement to either eliminate the need for veneers, reduce the amount of opacifiers needed to mask discolorat...
