A crown type has been described that offers the advantages of both ceramic veneers and metal crowns. More than 200 single crowns and three three-unit bridges of this type have been inserted with no failures after two years. University-based shear and compressive testing is currently being arranged to affirm perceived clinical strength of this new crown type. Comparison testing also will be performed with comparative values for the hybrid crown, all ceramic (various types), and porcelain-fused-to-metal.
已描述了一种兼具陶瓷贴面和金属冠优点的牙冠类型。超过200个这种类型的单冠和三个三单位桥已植入，两年后无失败案例。目前正在安排基于大学的剪切和压缩测试，以确认这种新型牙冠的临床强度。还将与混合冠、全陶瓷（各种类型）和烤瓷熔附金属冠的对比值进行比较测试。
