Introduction: Degenerative joint disease (DJD) is mildly prevalent in a pre-orthodontic population and can contribute to jaw pain and skeletal relapse post-orthodontic treatment.

Purpose: To determine whether craniofacial form or particular treatment modalities are related to TMJ condylar degeneration.

Materials and methods: The cephalometric radiographs of 61 subjects with moderate- severe condylar degeneration (as diagnosed from panoramic radiographs) were traced and treatment factors were recorded.

Results: Cephalometric findings of significance in this study include increased facial convexity, increased ANB, decreased SNB, decreased Pg-NA perpendicular, increased mandibular plane angle, increased gonial angle, increased overjet, and upright lower incisors when compared to cephalometric standards. Treatment modalities of significant prevalence are orthognathic surgery (23%) and Class II or III elastics (61%).

Conclusions: Results from this study, although inconclusive without a control group, indicate a retrognathic dolichofacial type. Patients requiring orthognathic surgery and with dental anteroposterior discrepancies tend to have more condylar degeneration
