Temporomandibular joint disorders (TMD) are among the most common problems in the jaw, face, and ear zones. There are multiple factors in the etiology of TMD. It is considered that its morphology may play a role in the etiology of the disease. This study aimed to evaluate the relationship of temporomandibular joint (TMJ) disorder with condyle length, ramus length, condyle width, corpus length, gonial angle, and ramus/corpus ratio.The study was conducted on a total of 100 patients, 50 were symptomatic and 50 were asymptomatic, aged between 16 and 66 years. Symptomatic patients were selected among the patients who presented to our clinic for at least one of the complaints of crepitation, clicking, and pain in the temporomandibular zone on both sides (bilateral). The control group was selected among asymptomatic patients who did not have any complaints in the temporomandibular zone. We evaluated its relationship with TMD by measuring condyle length, condyle width, ramus length, corpus length, gonial angle, and ramus/corpus ratio on CBCT. In the total population, condyle length, ramus length, and condyle width were longer in favor of the control group. However, there was no difference between the ramus/corpus ratio and corpus length. The width of the condyle in female patients with TMD, and the length of the corpus in male patients with TMD were higher in favor of the control group. There is a relationship between TMD and mandible morphology. Knowing the effectiveness of the morphology of the mandible in TME disorders is important in terms of informing individuals with risky morphology beforehand.
