Dental porcelain occasionally requires adjustment in circumstances that preclude reglazing. Porcelain refinishing kits are now available commercially. The effects of using one such kit on Vita VMK bonded porcelain was investigated qualitatively and quantitatively using scanning electron microscopic and surface profilometric techniques, respectively. The kit proved incapable of restoring a surface glaze to porcelain adjusted using a fine (red band) diamond bur, but was capable of reducing significantly the surface roughness (Ra) of adjusted porcelain. The importance of distinguishing between the integrity of the surface glaze and measurements of surface roughness is discussed. Confining the application of refinishing procedures to the surface adjusted is important to avoid unnecessary removal of the original surface glaze.
牙科陶瓷偶尔需要在无法重新上釉的情况下进行调整。现在市场上有陶瓷修复套件出售。分别使用扫描电子显微镜和表面轮廓测量技术,对使用其中一种套件处理维他VMK烤瓷的效果进行了定性和定量研究。结果表明,该套件无法为使用细粒度(红色标记)金刚砂车针调整后的陶瓷恢复表面釉质,但能够显著降低调整后陶瓷的表面粗糙度(Ra)。文中讨论了区分表面釉质完整性和表面粗糙度测量的重要性。将修复程序的应用局限于已调整的表面很重要,以免不必要地去除原始表面釉质。
