GI—I型粉浆涂塑铝瓷修复体折裂强度的测定

Determination of the fracture strength of GI-I slip casting aluminous ceramic crown

折裂强度反映修复体所能承受的最大力值。本研究测定了ＧＩ—Ｉ型粉浆涂塑铝瓷冠修复体和金瓷冠修复体的折裂强度，结果表明，ＧＩ一Ｉ型粉浆涂塑铝瓷冠的折裂强度为１２８７．７Ｎ，远低于金瓷修复体的折裂强度。

The fracture strength reveals the maximum force required to fracture a restoration. This study determined the fracture strength of GI- I slip casting aluminous ceramic crown. The results indicated that the fracture strength of GI- I slip casting aluminous ceramic crown was 1287. 7N,which was far lower than that of the metal-ceramic crown.
