Obviously, caution must be taken in performing any type of dental procedure, especially those requiring the patients to have their mouths open for long periods of time. The TMJ often demonstrates profound laxity in conjunction with generalized joint mobility and dislocation in these patients. Genetically defective collagen biosynthesis directly affects the fibrous stability of the retrodiscal tissues, thus causing recurrent subluxation. Recurrent subluxation was described by Goodman and Allison. The modality that is described is that of reducible, anteriorly displaced disk with an overlying neuromuscular component.
Joint disturbances are often secondary to laxity in joint tendons and ligaments.
Current therapy for these symptoms includes occlusal splints, anti-inflammatory agents, muscle relaxants, and physical therapy. Temporomandibular joint surgery is sometimes indicated to control subluxation. The periodontal status in the patients also needs to be closely monitored both clinically and radiographically in these patients. These tissues are very prone to gingivitis, periodontitis, and severe bleeding after invasive procedures. The oral mucosa's fragility, ease of bruising, and delayed wound healing also places limitations on dental treatment.
