Abstract
Excessive teeth wear may result in the complications such as esthetic problems, hypersensitivity, and loss of vertical dimension. This clinical report focuses on the causes of severely worn dentition and the full-mouth rehabilitation of a patient with rheumatoid arthritis for 20 years. An interview, clinical and radiological examinations were performed to analyze the causes and decide the treatment plan. After delivery of the final prostheses, a night guard was used to protect the restorations and temporomandibular joints. The patient was satisfied esthetically and functionally.
