Ankylosing spondylitis associated with craniomandibular disorder--a combined orthodontic and prosthodontic therapeutic approach.

Abstract

Ankylosing spondylitis is a disease that causes inflammatory changes of the involved joints. Although the initial clinical signs are pain and discomfort, synovial changes progressively involve all the axial joints, including the temporomandibular joint (TMJ). Eventually, bony alterations develop (condylar erosions, flattening, sclerosis) that affect the position of the condyle, the superior joint space, and the range of movements. These symptoms correlate with the severity of the disease. Besides physiotherapy and surgery, no dental rehabilitation has been reported for these patients. This report of a female patient with ankylosing spondylitis and a TMJ disorder emphasizes dental rehabilitation. The aim of the splint, orthodontic, and prosthodontic treatment was to relieve the subjective symptoms through establishing a stable optimum occlusion. Anamnestic, laboratory, and clinical findings including pre- and postradiographic examination records are presented.
