In search for more durable aesthetics and less invasive solution, porcelain veneers which was introduced in the early 1980s demonstrate
excellent clinical performance and provide an opportunity to enhance the patient’s smile in minimally invasive way.
These restorations can restore slight discolorations, abrasion or fracture, modify tooth’s shape, close diastema and improve minor alignment problems these veneers must be bonded to teeth following the principles of adhesion.
Cementation using pre heated restorative composite
Previously done on the tooth: immediate dentin sealing during the preparation stage, then, before cementation (2nd step).
► On the tooth surface: sandblasting (27 microns alumina), etching of enamel margins (H3PO4, 37%), silanisation of the composite base (heat activation), hydrophobic bonding layer (uncured).
► On the feldspathic veneer intaglio: etching (Hydrofluorhydric acid), silanisation, uncured layer of hydrophobic bonding.
This protocol has been first described by D. Dietschi and P. Magne. Material from: David Gerdolle.
