Color stability of porcelain-fused-to-titanium restorations after repeated firings / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of repeated firings on color of porcelain-fused-to-titanium restorations.</p><p><b>METHODS</b>Twenty standard porcelain-fused-to-titanium specimens were made with Dentsply DETREY TiBond C3 and Dentaurum rematitan Til. Then they were fired 1, 2, 4, 7, and 10 times. Color measurement was done after each firing.</p><p><b>RESULT</b>Most of the color parameters had no significant difference after firing except for a* and Hab. All the color difference among groups were smaller than 1.0 (deltaE < 1.0).</p><p><b>CONCLUSION</b>Repeated firings will not affect the color stability of porcelain-fused-to-titanium restorations.</p>
