Long-term performance of feldspathic ceramic veneers in anterior rehabilitation: A seven-year clinical case report

The purpose of this case report is to discuss the use and the predictable prognosis of feldspathic ceramic veneers for the anterior dental rehabilitation, especially when the preparation is beyond the traditional indication. Feldspathic ceramics are preferred in terms of aesthetics such as translucence and shade that makes it almost similar to dental enamel. But there is the issue of mechanical strength that comes into play whenever they are applied over rather diminished tooth structures. The present clinical case describes the situation where feldspathic veneers were bonded to all the anterior teeth, including centrals, laterals, and canines to which more than 2 mm of unsupported dental hard tissue was prepared. The highly dense veneers with a thickness higher than that recommended for AO manufacturing revealed good levels of durability and stability in seven years of their implementation. The success of this case really lies in the great bonding procedures and the solid knowledge of the material properties. This paper argues against a hypothesis stating that feldspathic veneers are not suitable for extensive tooth reduction, while proving their success even in unfavorable circumstances. Thus, according to the present study, the use of feldspathic ceramics in complex restorative situations proved to be clinically and aesthetically effective and is worthy to be further investigated in challenging clinical conditions.
