title: Restoring anterior maxillary dentition using alumina- and zirconia-based CAD/CAM restorations.
abstract: Despite proven strength, durability, and improved esthetics, ceramometal restorations have not consistently enabled the most esthetic, lifelike reproduction of natural dentition. Also, inherent weaknesses in many metal-free materials have precluded their use in the high stress-bearing posterior region. Therefore, as a result of the need for esthetic and durable all-ceramic restorations, manufacturers have introduced ceramics with an increased alumina or zirconia content that are recommended for placement anywhere in the mouth for single units and as far back as the first premolar.
