Effect of Repeated Firings on Microtensile Bond Strength of Bi-layered Lithium Disilicate Ceramics (e.max CAD and e.max Press).

Hamid Jalali, Zeinab Bahrani, Somayeh Zeighami,

<h4>Aim</h4>To achieve acceptable contour, color, esthetics, and occlusal relations, the porcelain may be subjected to several firing cycles. This study sought to assess the effect of multiple firing cycles on the microtensile bond strength (MTBS) of lithium disilicate-based ceramics (e.max Press, e.max CAD).<h4>Materials and methods</h4>IPS e.max computer aided design (CAD) ...
