Malocclusions in Iraqi Temporomandibular Disorder (TMD) Patients

Wajnaa F. Qassim

Abstract: This study was achieved to estimate the association between unpreferable occlusal relation and the development of temporomandibular disorders. The study was applied on 84 patients 47 females and 37male with mean age of 34.7 years (range 13-64) years. All patients were evaluated clinically for signs and symptoms of temporomandibular disorder. The results showed that temporomandibular disorder developed in patients with defective occlusal contact regardless of their type of Angles classification and most patients have normal class I relation (78.6 %). The main occlusal discrepancies which are blamed as play a causal role in the development of temporomandibular disorder were deep over bite (10.5 %), followed by single tooth cross bit (5.8 %), then anterior open bite, posterior open bite and posterior cross bite which show the same percentage of (3.5 %). In conclusion, temporomandibular disorders seem to be related to dental malocclusion rather than abnormal arch relation and more evident in the vertical mandibular discrepancy than horizontal.
