Abstract
Patient: The patient, a 52-year-old female, visited our clinic with chief complaints of aesthetic and masticatory disorders. We suggested that a root fracture of the upper right canine had been caused by an overload on the maxillary anterior teeth serving as the occlusal support. This had resulted from a decrease in the occlusal vertical dimension caused by long neglect of the edentulous lower bilateral molars. Occlusal reconstruction was done using a bite-raising denture anda temporary bridge.
Discussion: Occlusal reconstruction was done by bite-raising denture and temporary bridge for a case of the infraocclusion without occlusal support. But it is thought that periodical recall is necessary because there were few residual teeth and convalescence is uneasy.
Conclusion: Because infraocclusion with little occlusal support easily leads to occlusal collapse, aggressive treatment making use of bite raising and occlusal reconstruction is recommended for prevention.
