采用三点弯曲试验，对10个品牌的牙科修复陶瓷的相对弯曲强度进行了评价。材料包括三种低熔和一种高熔的金刚石瓷和六种目前临床使用的增强牙科修复陶瓷。所研究的增强陶瓷材料利用了许多不同的增强工艺，包括氧化铝和陶瓷纤维增强和控制结晶。研究结果表明，不同材料的断裂强度测定值之间存在显著差异。控制结晶和氧化铝增强工艺似乎是提高修复牙科陶瓷抗弯强度的适当手段。
The relative flexural strengths of ten brands of dental restorative ceramics were evaluated by a three-point bending test. The materials consisted of three low-fusing and one high-fusing feldspathic porcelains and six reinforced dental restorative ceramics which are currently in clinical use. The reinforced ceramic materials investigated utilized a number of different strengthening processes, including alumina and ceramic fiber reinforcement and controlled crystallization. The results of the investigation indicate that significant difference exist among the measured breaking strengths of the various materials. The processes of controlled crystallization and alumina reinforcement appear to be adequate means of improving the bending strength of restorative dental ceramics.
