Abstract
Patient: A 66-year-old female complained denture mobility and poor mastication. She had edentulous maxillar and the nearly edentulous mandible with extruded right canine and two remaining roots. Denture stabilizer had been incorrectly accumulated in layers to the maxillary denture. As results of examination, the patient was diagnosed with masticatory disorders due to maxillary denture mobility caused by the extruded mandiblar right canine. The maxillary complete denture, in which occlusal contact in the anterior tooth area was avoided, and a mandibular overdenture were placed. Questionnaires regarding masticable foods were used to evaluate the treatment effects.
Discussion: It was considered that masticatory disorders were occurred due to the patient's long-term misuse of denture stabilizer to increase the mobility of the maxillary denture raised by the mandibular canine.
Conclusion: Denture retention and stability were achieved by establishing appropriate denture base morphology, occlusal height, mandibular position, artificial teeth arrangement, and molar occlusal contact.
