A case of implant prosthesis treatment for a patient with masticatory disorder and occlusal collapse

Abstract

Patient: The patient was a 64-year-old woman who presented with the chief complaint of a mastication disorder caused by a maxillary anterior tooth defect and bilateral mandibular free-end missing. Uneven alignment of the occlusal plane and occlusal collapse were present. We performed occlusal reconstruction with an implant prosthesis of the maxillary and mandibular defects for rehabilitation.

Discussion: Fixed-implant rehabilitation improved masticatory function. Our goal was to achieve occlusal stability by providing a full-maxillary prosthesis. Approximately four years after installing the final prosthesis, the alignment of the remaining teeth in the implanted region has been retained over time through successive maintenance.

Conclusions: The mastication disorder in this patient was rehabilitated by occlusal reconstruction with implant prosthetics for the defect and occlusal elevation of the remaining teeth by crown restoration.
