A case report in which piezography was applied to a patient with edentulous mandible and maxilla with severe ridge resorption to improve masticatory disorder

Abstract

Patient: The patient was a 67-year-old female. She visited the hospital complaining of the poor fit of her maxillary and mandibular dentures. The mandible had severe residual resorption and the mandibular complete denture had a poor fit. The setting position of the denture base edge, arrangement positions of artificial teeth, and morphology of the polished surface were inappropriate, and the stability during denture functioning was impaired. Hence, complete dentures were produced using piezography.

Discussion: By applying piezography to the patient, artificial teeth were arranged and a polished surface of the denture base was made. The artificial teeth arrangement and polished surface morphology were harmonized with the muscle movement around the mouth and the tongue movement, and as a result, masticatory function was recovered.

Conclusion: In this case, by applying piezography, we were able to produce complete dentures that did not impair stability during functioning.
