A thesis submitted to the College of Dental Medicine of Nova Southeastern University of the degree of Master of Science in Dentistry. Introduction: The association between occlusal characteristics and Temporomandibular Disorders (TMD) has been previously investigated, however, debate still exists. Objective: To compare the occlusal characteristics of subjects with anterior disc displacement with reduction (ADDR) to that of asymptomatic controls. To investigate whether an association exists between specific occlusal characteristics and ADDR. Materials & Methods: 99 de-identified dental casts (68 ADDR subjects and 31 asymptomatic subjects) from Tufts University School of Dental Medicine were analyzed. Eleven occlusal characteristics were evaluated for each set of casts: 1. Angle's dental classification of malocclusion 2. overjet 3. overbite 4. intercanine distance 5. intermolar distance 6. curve of spee 7. arch form 8. tooth size arch length discrepancy 9. crossbite 10. Bolton discrepancy 11. premolar extractions. Results: Significant associations were found between bilateral AADR and a tapered arch form (ppppp
