Most dental restorative materials are adhesive, which means that they 'stick' or bond to minimally invasive preparations (that is, minimal removal of healthy tissue). The surface of the tooth needs to be conditioned so that the Restoration can adhere properly. 'Etch-retained restorations' are any repairs attached to the tooth in this way --either composite fillings, veneers, inlays or onlays.
Some of the text is courtesty of www.bdasmile.org
- The bond between the tooth and restoration can be very strong so that the restoration stays in place for a long time.
- Should the bond break, it is possible to simply add material.
- Because restorations are held in place by the bonding agent and not just by the shape of the tooth, less of the natural tooth is lost in preparation.
