CBCT reveals bony changes in the condyle including flattening, osteophyte formation (bone spurs), erosion, sclerosis (hardening), and ankylosis (fusion). It also shows condylar asymmetry, joint space narrowing, and the shape of the glenoid fossa. Soft-tissue disc position requires MRI, but the majority of TMJ diagnoses begin with understanding the bony anatomy.

Not always. Intermittent clicking without pain is common and often does not require imaging. CBCT is indicated when clicking is accompanied by pain, progressive limitation of jaw opening, locking episodes, or when conservative treatment has not resolved symptoms. The scan determines whether bony degeneration is contributing to the problem.

CBCT shows bone, not soft tissue, so the articular disc itself is not directly visible. However, indirect signs of disc displacement — such as joint space changes, condylar remodeling, and positional asymmetry — are clearly seen. If soft-tissue disc evaluation is needed, MRI is the appropriate follow-up imaging modality.

TMJ degeneration is frequently bilateral even when symptoms are one-sided. The unaffected joint serves as a morphological reference for comparison. Bilateral scanning also reveals compensatory changes in the asymptomatic joint that may affect long-term prognosis and treatment planning.

By documenting the starting condition of the condyles and joint spaces, CBCT provides a baseline against which treatment response can be measured. If splint therapy successfully decompresses the joint, follow-up imaging may show improved joint space. If condylar degeneration continues despite conservative treatment, the imaging record supports escalation to more aggressive intervention.

CBCT can identify bony joint pathology that correlates with TMJ-related headaches, but headache etiology is complex. A clinical examination that assesses muscle tenderness, jaw function, and trigger points is equally important. CBCT may confirm the TMJ component of your headache while ruling out other dental causes such as infection or impacted teeth.

Condylar resorption is the progressive loss of bone from the mandibular condyle, leading to shortening of the ramus and potential open bite deformity. CBCT shows the resorptive changes clearly — irregular condylar surfaces, decreased condylar volume, and altered joint space — and allows measurement of the degree of ramus shortening. Serial CBCT scans can track progression over time.

No. The scan takes 12 to 20 seconds and requires no mouth opening beyond a natural rest position. Patients with limited jaw opening or pain on opening can be scanned comfortably because the machine rotates around the head without requiring a bite block or wide opening.

Yes. Osteoarthritis of the TMJ produces characteristic CBCT findings including condylar flattening, osteophyte formation, subchondral cyst formation, and erosive changes. Rheumatoid and psoriatic arthritis can also affect the TMJ, and CBCT detects the bony manifestations of these conditions as well.

The field of view and imaging protocol are adjusted to capture both joints with best detail. The reconstruction is viewed in planes oriented along the long axis of each condyle rather than standard anatomical planes. This protocol-specific approach provides the most diagnostic information about joint morphology.

Yes, with your authorization. ADSC provides imaging reports and DICOM data to any provider involved in your TMJ care — physicians, physical therapists, oral surgeons, or orthodontists. Multidisciplinary communication is essential for effective TMJ management.

Coverage depends on your dental plan and whether TMJ treatment is a covered benefit. Some plans cover diagnostic imaging for TMJ disorders, while others exclude TMJ-related services entirely. The ADSC billing team checks your benefits before the appointment and provides a clear cost estimate.

Yes. Juvenile idiopathic arthritis, trauma-related condylar growth disturbances, and congenital condylar hypoplasia can all affect children and are visible on CBCT. Pediatric TMJ imaging uses reduced field and dose settings appropriate for smaller anatomy.

The doctor reviews findings with you, correlates imaging with clinical examination results, and presents a treatment plan. Options range from conservative management — splint therapy, muscle relaxation techniques, medications, physical therapy referral — to surgical intervention for advanced joint disease. Treatment is staged, and the least invasive effective option is recommended first.

Follow-up imaging is guided by clinical response. If symptoms resolve with conservative treatment, repeat imaging may not be needed. If symptoms persist or worsen, a follow-up scan at 6 to 12 months can document whether bony changes have progressed, stabilized, or improved.
