The dimensional change of a new castable ceramic material (CD-200) was measured after casting, ceramming, and surface coloring. The marginal and internal adaptations of single crowns were evaluated, as was the fracture strength of single crowns and fixed partial dentures. The material expanded 0.57% after casting, ceramming, and application of surface colorant. Marginal openings ranged between 2.8 and 11.2 microns. Single crowns exhibited fracture strengths lower than or comparable to Dicor single crowns, and fixed partial dentures made from CD-200 were weaker than those fabricated with Dicor.
对一种新型可铸陶瓷材料（CD - 200）在铸造、烧结和表面着色后进行尺寸变化测量。评估了单冠的边缘和内部适合性，以及单冠和固定局部义齿的断裂强度。该材料在铸造、烧结和施加表面着色剂后膨胀了0.57%。边缘开口范围在2.8至11.2微米之间。单冠的断裂强度低于或与Dicor单冠相当，由CD - 200制成的固定局部义齿比用Dicor制作的更脆弱。
