  • Title: Clinical use of a new castable glass ceramic material.
    Author: Maruyama T, Koh N, Hino T, Miyauchi S.
    Journal: Int J Prosthodont; 1991; 4(2):138-46. PubMed ID: 1781875.
    Abstract:
    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.
