A case report: Partial denture treatment in a patient with huge mandibular tori located from the incisor area to the molar area

Abstract

Patient: The patient was a 70-year-old male complaining of recurrent fracture of a mandibular partial denture. It was suggested that the fracture was attributable not only to insufficient denture space narrowed by mandibular tori and tongue feeling, but also to excessive functional force due to bruxism and food preference. The patient did not consent to osteoplasty of mandibular tori. A metal framework was applied, but structural vulnerability remained. To reduce the adverse effects of excessive functional force, selection of occlusal scheme, acquisition of adequate support area and behavior therapy for bruxism and food preference were implemented.

Discussion: In this case, strengthening of the mechanical properties of the denture, reduction of functional force on the denture and dispersion of functional force were necessary to avoid denture fracture.

Conclusion: For this high-risk case of denture fracture, multiple approaches to control denture fracture contributed to achieving a successful outcome.
