The disc strengths of aluminous porcelain fired on to both platinum and palladium foil matrices have been determined. Also, the effect on strength of removing the matrices has been measured. The appearance of the separated metal and porcelain surfaces has been studied using scanning electron microscopy, and energy dispersive X-ray analysis has been used to evaluate the chemical composition of these surfaces. Reasons for the increase in strength observed when the matrix is left intact are discussed. Practical suggestions for obtaining stronger jacket crowns are presented.
已测定了在铂箔和钯箔基体上烧制的铝瓷的圆盘强度。此外,还测量了去除基体对强度的影响。使用扫描电子显微镜研究了分离后的金属和瓷表面的外观,并使用能量色散X射线分析来评估这些表面的化学成分。讨论了基体保持完整时观察到强度增加的原因。提出了获得更强固位冠的实用建议。
