Case of the Week: Subpontic osseous hyperplasia (subpontic hyperostosis) 7


This week I’m sharing examples of excess bone growth in response to a pontic – subpontic osseous hyperplasia or subpontic hyperostosis.  There have been some theories as to etiologies including a low grade inflammatory process causing the body to create more bone that can reach up to the pontic in some cases. A few reported cases show that if the pontic is removed the bone will slowly atrophy back to normal limits and in one case when a new pontic was placed the excess bone growth came back.  I find it really interesting. 😀

Here are some examples (sorry for the small images).

Bitewing radiograph - smaller but still excess bone growth under a pontic.

Sort of a bitewing - note the radiopaque mass with radiopacity of bone inferior to the pontic.
