Subpontic osseous hyperplasia: a five-patient report

W C Daniels1

  • 1Area Dental Laboratory, Sembach Air Base, Germany.

Summary

Subpontic osseous hyperplasia, a benign bone growth under dental bridges, is reported in five new cases. Chronic irritation and functional stresses are potential causes, with recurrence noted after surgical removal.

Area of Science:

  • Dentistry
  • Oral Surgery
  • Prosthodontics

Background:

  • Benign osseous proliferation beneath pontics of mandibular posterior fixed partial dentures is a recognized clinical entity.
  • Thirty-four cases have been previously documented in dental literature.

Observation:

  • This report details five additional cases of subpontic osseous hyperplasia in the posterior mandible.
  • These growths occurred under the pontic areas of fixed partial dentures.

Findings:

  • One patient experienced recurrence of osseous hyperplasia after surgical excision.
  • Another patient showed continued osseous proliferation even after pontic modification.
  • Chronic irritation and functional stresses are discussed as potential etiologies for this condition.

Implications:

  • Understanding the etiology of subpontic osseous hyperplasia is crucial for effective management.
  • Treatment considerations include surgical intervention and addressing potential causative factors like chronic irritation and functional stresses.
  • Further research may elucidate the precise mechanisms driving this benign bone proliferation.
