Implant-supported fixed prosthesis rehabilitated masticatory disorders caused by reduction of occlusal supporting area: a case report

Abstract

Purpose: The patient was a 69-year-old female with the chief complaint of masticatory disorders in the right molar region. The abutment teeth of her fixed prosthesis in the upper left molar region needed to be extracted. Attrition of the occlusal surface of the dental prosthesis indicated that the patient had bruxism. Since the occlusal supporting area on both sides was almost completely missing, the edentulous sites were reconstructed with implant-supported fixed prostheses.

Discussion: Implant-supported prostheses for bruxism patients need to be monitored carefully, especially the occlusal relationship which may cause excess loading on the implants.

Conclusion: Implant-supported fixed prostheses were effective for this patient whose occlusal supporting area on both sides was almost completely missing. In this case, wearing an occlusal splint at night and regularly scheduled check-ups resulted in the preservation of masticatory function and occlusal support without any complications up to 4 years 6 months so far.
