Abstract

A number of modern materials are available which allow placement of highly aesthetic anterior restorations. However, some systems are complex and technique sensitive. The authors describe a layering technique for the provision of direct aesthetic anterior composite restorations suitable for a general practice setting.

Clinical Relevance: Aesthetic restorations can be provided directly and in a conservative manner using composite resin, often avoiding the need for more destructive indirect techniques.

Article

Resin composite provides the most aesthetic direct restorative material for restoring teeth. Composites offer the opportunity for minimal preparation compared to more destructive indirect alternatives. Some composite materials are specifically intended to be used to build layered restorations, eg Miris (Coltène/Whaledent, AG, Feldwiesenstrasse 20, 9450 Altstätten, Switzerland), Ceram X Duo (Dentsply, York, PA, USA), Enamel HFO (Micerium SpA, 16036 Avegno (Ge) Italy). Such composite systems differ from other composites in that they have different characteristics between the enamel and dentine composite shades.

Composite resins are available with a range of optical characteristics, having a range of translucencies and colours. Whilst in certain situations it may be feasible to create an adequate appearance by using a single composite shade, composite systems intended for layered restorations are composed of distinct enamel and dentine shades. The difference between the enamel and dentine composite is marked with a high opacity and chroma for dentine shades and high translucency and low chroma for enamel (Tables 1 and 2).
