Subpontic osseous hyperplasia: a case report
1Department of Periodontics, Baylor College of Dentistry, Texas A&M University System, PO Box 660677, Dallas, Texas 75266-0677, USA.
Abstract:
Subpontic osseous hyperplasia is an ectopic growth of bone occurring on the edentulous ridge beneath a fixed partial denture replacing a mandibular first molar. A 56-year-old woman experienced an enlargement of the hard and soft tissues beneath the pontic region of a fixed partial denture replacing her mandibular left first molar. Following removal of the fixed partial denture, the bony enlargement was surgically removed, and the bony fragments were submitted for histologic analysis, which demonstrated mature lamellar bone and appositional growth. One year postoperatively, there has been no recurrence of the lesion. The possible etiologies and treatment modalities are reviewed and a rationale for treatment is presented.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
