Replacing Composite FPD
This patient presented with on old temporary bridge, I advised the patient that is was starting to get some decay and it wouldn’t last much longer.

I gave the patient a three options:

  1. Leave it till it falls out – hopefully will be able to fix it when this happens.
  2. New temporary bridge – not as long lasting, less expensive, takes less time.
  3. Porcelain bridge – lasts longer, more expensive and takes longer.

Patient decided to go with option 3, Porcelain bridge. So I set out replacing her resin FPD with something a little more traditional.

One thing I like to keep in mind is that it is the same distance to the pulp for caries regardless of the restorative material. I find most resin FPD fail because of caries interproximally. They are exceedingly difficult to bond and polish in this area.

The most common point of failure of bonded composite FPD is caries interproximally, likely because this area is difficult to bond and finish properly.
