A case of complete denture applied by the flange technique and soft denture liner for severe mandibular residual ridge resorption

Abstract

Patient: A 66-year-old woman presented to our hospital complaining of dislocation of a |1 artificial tooth from a complete upper denture as well as chewing difficulty and pain due to mobility of a complete lower denture. As severe mandibular residual ridge resorption had occurred, a new complete lower denture was created using the flange technique, and an acrylic soft denture liner was applied.

Discussion: Use of the flange technique to shape the polished denture surface in a manner that reflected the function of the tongue and perioral muscles, and application of an acrylic soft denture liner to relieve pain in residual mucous membranes contributed to a favorable prognosis in the present patient.

Conclusion: In an edentulous patient with severe residual ridge resorption, a new complete lower denture having appropriate polished denture surface fabricated by applying an acrylic soft liner achieved improved masticatory function and led to high patient satisfaction.
