I've worn a 3 unit bridge for 23 years. If I would like to have the pontic replaced with a dental implant, what are the dangers? Assuming I have a bone graft, will the bridged teeth be stable?
The first step is to evaluate the bone in the pontic area. This can be done with a dental x-ray, but best performed by a ct-scan of the area. During the examination the remaining teeth need to be evaluated periodontally.
Assuming the bone is sufficient, adding an implanted tooth in the pontic area, will take some of the stress off the adjacent teeth and increase the lifespan of these teeth.
