A case report of oral rehabilitation for a patient with infraocclusion due to severe tooth erosion

Abstract

Patient: A 29-year-old female complained of esthetic and masticatory disturbance with tooth erosion due to an eating disorder. All tooth crowns were remarkably eroded such that dentin was exposed, and the vertical dimension of occlusion (VDO) was decreased. VDO was ideally restored by referring to the mean anatomical crown length with occlusal overlay splints and provisional restorations. After long-term follow-up, the final prosthesis (all-ceramic crowns) with cuspid protected occlusion was applied.

Discussion: The occlusal overlay splint, which can be applied without tooth preparation, was helpful for occlusal reconstruction in a patient with mental instability.

Conclusion: In this patient with tooth erosion due to an eating disorder, a favorable outcome was achieved by oral rehabilitation with occlusal overlay splints and provisional restorations.
