| In the
past two decades adhesive technologies have extended prosthetic possibilities
dramatically, as reliable resin bonding can be achieved to all restorative
materials. This article reviews the current status on resin bonding to metal
and ceramic materials. Bonding methods differ between precious and non-precious
alloys and between silica-based and silica-free oxide ceramics. Using devices
designed for intraoral air-abrasion on metals or oxide ceramics and
hydrofluoric acid etching micro-retentive bonding surfaces can be produced
chair-side. Specific primers or resins containing adhesive monomers are used to
achieve chemical bonding to any substrate. Exemplary clinical cases are
presented to show some of the prosthetic applications achievable with adhesive
technologies. |
