A maxillary edentulous case treated with a removable prosthesis retained by an undercut on a bone defect

Abstract

Patient: A 75-year-old male patient complained of his dentures easily coming off and associated eating difficulties. His edentulous maxilla had a defect on the left side, for which he had undergone free flap reconstruction. His maxillary denture did not have enough retention. We extended the obturator to the undercut on the defect and fabricated a maxillary denture using a hollow obturator to improve the fit and retention of the denture.

Discussion: The good outcomes were attributable to: retention and stability of the maxillary denture provided by the obturator extended to the undercut on the defect; use of a hollow obturator; and improved retention by reducing the denture weight.

Conclusion: In this edentulous patient who underwent free flap reconstruction of a defective jaw, a satisfactory treatment outcome was obtained by using an undercut on the defect for denture retention and using a hollow obturator.
