Note: If not previously silanated by lab, confirm restoration fit on model, clean restoration and apply silane in advance of patient visit.  Silane bond  "maturation" has been shown to improve bonding to ceramic. Silane will not subsequently be removed by ultrasonic cleaning in alcohol or phosphoric acid cleaning after patient try-in.
