MRI in Diagnosis of Craniomandibular Dysfunctions


Visualization of the temporomandibular joint (TMJ) is constantly evolving with the improvement of technology. Magnetic resonance imaging is commonly used to evaluate the TMJ due to the high contrast resolution and the ability to obtain dynamic images to demonstrate the functional capability of the joint.

Aim — to determine the functional changes after TMJ splint therapy conducted at various stages of intra-articular disorders.

Data and methods. We conducted a survey, clinical examination and MRI of TMJ of 37 patients with temporomandibular disorders (TMD). Two groups of patients were formed according to the received MR picture of TMJ.

Results. The study highlighted that regression of pain in TMJ and masticatory muscles, and normalization of functional parameters after splint rehabilitation occur more often in the first group of patients, who have disorders of the articular disc of the TMJ.

Conclusion. In both groups of patients we noted positive dynamics of functional parameters of TMJ, reduction of pain in TMJ and masticatory muscles. Though 36,8% of the second group of patients, who have bone remodeling of TMJ condyles, didn’t show dynamics of functional parameters. Consequently, the use of splint in one third of patients with temporomandibular joint condyles destruction is effective for TMJ and muscular pain reduction.
