ABSTRACT
UNLABELLED: The functional and esthetic restoration of severely compromised anterior teeth is a challenge to clinicians in their daily practice. The duplication of the optical characteristics of an intact tooth, including shade, translucency, and fluorescence, is often made difficult by the use of metal infrastructures, such as post-and-cores and copings. The development of reinforced ceramics and non-metallic post systems made possible the generation of metal-free ceramic restorations in severely compromised anterior and posterior teeth. This article discusses one available technique for the generation of a single all-ceramic restoration involving the use of a zirconia- or leucite-reinforced post-and-core system and of an all-ceramic crown system. A representative clinical case is presented illustrating the potential of the technique. CLINICAL SIGNIFICANCE: Modern ceramic restorative systems offer the possibility to closely match the natural optical characteristics of lost tooth structure. Posts, cores, and copings fabricated in ceramic materials represent a promising alternative to metals in the restoration of severely compromised anterior teeth.

The combination of intracoronal and extracoronal bleaching represents a conservative treatment to restore esthetics to darkened or stained nonvital teeth. Notwithstanding the eventual risks and difficulties accompanying such technique, nonvital teeth often can be successfully lightened. This article presents a few guidelines for bleaching nonvital teeth as well as a clinical case to illustrate the indications and clinical protocol for the technique.

A patient whose teeth had been severely stained by improper use of tetracycline was treated through a direct system of facial veneering. The technique associates the use of a light-activating glass-ionomer cement with two kinds of light-activating composite resin. Satisfactory esthetics were obtained immediately.

Esthetics and function were restored to a fractured maxillary central incisor by reattaching the tooth fragment with the "sandwich" technique (glass-ionomer cement and composite resin). After 3 years, the tooth showed optimal fragment rehydration, presence of pulpal vitality, absence of sensitivity, and a discrete color alteration in the line between the fragment and the dental remnant.
