Abstract

The resin-bonded bridge (RBB) is a predictable technique that has a useful place in modern day dentistry. Practitioners' main concerns, regarding this technique, are a lower survival rate when compared with conventional prostheses, and unpredictable aesthetics. Unfortunately, the minimal preparation and adhesive concepts used with RBBs complicates provisional cementation. Ideally, the RBB should be assessed as if it were the definitively bonded prosthesis. It is possible to achieve a good final aesthetic result as the grey shine-through of the metal wing can be eliminated by the use of opaque resin cements such as Panavia 21 OP. Ideally, the restoration should be assessed with an identical opaque try-in paste but, unfortunately, such a proprietary paste is not available. This paper describes the use of Dycal as a try-in paste for provisionally cementing a resin-bonded bridge and the benefits this offers.
