Abstract: | Textured opaque porcelains have been introduced to improve the appearance of metal ceramic restorations by increasing light refraction. This investigation compared the shear bond strength of a textured opaque porcelain with that of a conventional opaque porcelain. Opaque and body porcelains were fired onto six different alloys and the specimens were loaded to failure by applying shear force at the alloy-porcelain interface. No significant differences in bond strength were found between the textured and conventional opaque porcelains for any of the alloys tested. |
