Relationship between Temporomandibular Joint Disorders (TMD), malocclusion and craniofacial deformity is an extremely critical issue in dentistry field and still controversial. To investigate the prevalence of Temporomandibular Joint Disorders (TMD) and its relationship with different types of Class III malocclusion, this study was undergone though a pre-established clinical form among 30 patients (19,9±4,459) with class III malocclusion. The findings of the study has shown that the prevalence of TMD was around 66,7%. It was 52,6% among patients having achieving their treatment. The relationship between TMD and class III malocclusion was not statistically significant (P= 0,297) before treatment and it was at the limit of significance after treatment (P= 0, 057). Concerning harmful factors for TMD, gender and occlusal disorders were investigated in this study but did not play a significant part in the establishment of this disorder. To establish a cause-effect relationship, prospective longitudinal studies with large and representative samples are needed, integrating an approach concerning psychosocial and physical factors in the screening and management of TMD especially among Class III orthognathic surgery patients.
