Patient: The patient was an 80-year-old man who complained of difficulty in eating due to instability of his mandibular denture. He was diagnosed with dysmasesis resulting from instability of complete dentures. In particular, the mandibular residual ridge showed severe resorption. The mandibular residual ridge partially did not have keratinized mucosa. Complete dentures were fabricated using closed-mouth functional impression.
Discussion: In the area with severe residual ridge resorption, it was difficult to determine the denture border by the operator-initiated border molding. The denture border was determined using closed-mouth functional impression which is one of the impression methods using patient-specific movement, and extended to not only attached mucosa membrane but also partially unattached mucous membrane where functional movement is not disturbed.
Conclusion: The use of closed-mouth functional impression in the fabrication of complete dentures was effective in restoring masticatory function in an edentulous patient with severe residual ridge resorption.
