CBCT Assessment of Condylar Position in Patients with Temporomandibular Dysfunction

Radiographic analysis provides useful and diagnostic information regarding the status of the joints. The objective of this study was to utilize CBCT data and viewing software tools to analyze and measure the condylar position within the glenoid fossae of patients presenting with various signs and symptoms of temporomandibular dysfunction. The condylar position of these symptomatic patients was then compared to a group of existing norms for normal condyle position within the fossa. Changes at the level of the occlusion resultant to condylar position change will be discussed and illustrated.

Learning Objectives:

• Recognize abnormal condylar positions on a CBCT.
• Anticipate potential changes at the level of the occlusion due to abnormal condylar position.
• Appreciate the relationship between TMJ dysfunction and condylar position.
