Cap/crown given on tooth after root canal treatment reinforces the strength of the tooth. Ceramic what you have mentioned here is called PFM (porcelain fused to metal). The advantage with this is the cost ie economic and the drawback of this is ,it has a metal layer inside which may cause blackish colour change on your gums over a period of time. All ceramic/zirconia crown on the other hand does not have this metal layer and is more natural looking compared to PFM cap.drawback is the cost. If cost is not a factor then zirconia may be the better choice.
