Clinical aspects of resin-bonded bridges

Resin-bonded bridges have emerged as an attractive, minimally invasive prosthodontic option for the restoration of edentulous spaces. Although success rates, determined by retrospective studies, vary greatly, resin-bonded bridges now have success rates approaching those of their cemented counterparts; success is dependent, however, upon appropriate design and careful technique. The metal framework must be rigid and of sufficient surface area to afford secure adhesion to the underlying teeth. Tooth preparation should be restricted to enhancing the bonding area, and it is important that prostheses are designed to maintain axial loading, and guidance upon metal.
