Preparation of teeth for esthetic restorations

Preparation details have been described for a porcelain veneer restoration on the most commonly used teeth. With operator knowledge of the preparation, sharp instrumentation, and, most of all, patience, it is possible to place a restoration that may last as long as any others outside of those made of cast or direct gold. It is imperative to remember that this type of conservative "esthetic" dentistry should be performed only on canine-guided occlusions after equilibration (if necessary) (Fig. 13). Even then, it still is possible to fracture a veneer accidentally (Fig. 14). Prior to beginning treatment, it is prudent to inform the patient of the pros and cons of using porcelain veneers, including a warning of possible failure.
