The Benefits of CBCT in Orthodontics

Cone beam computed tomography (CBCT) has infiltrated every dental specialty over the past few years, including orthodontics. In addition to aiding in the assessment of skeletal and dental structures, localizing and evaluating impacted teeth and supernumeraries and TMJ assessment, CBCT also plays a vital role in airway analysis, the planning of temporary anchorage devices, the fabrication of custom orthodontic appliance and digital model creation and storage. Other benefits include improved diagnoses, faster examinations and enhanced patient communication and case acceptance.

Diagnosis and Treatment

TMJ Assessment—CBCT systems with multiple fields of view give doctors the flexibility to assess temporomandibular joint changes, as well as the surrounding structures. Not only are CBCT scans more accurate than 2D imaging, but one 360 degree scan can capture both the right and left TMJ, thus simplifying patient positioning.

Airway Analysis—As airway analysis becomes more widespread in orthodontics, dedicated 3D imaging software will allow doctors to visualize constrictions by segmenting the airway in a few clicks. These visually appealing 3D images can also help doctors communicate with patients.

Temporary Anchorage Devices (TADs)—CBCT gives doctors a highly detailed overview of bone quality and quantity, the location of the sinuses and root proximity, all vital to know before considering placing TADs. Three-dimensional imaging software can also simulate implant placement  for increased confidence and a more accurate treatment planning. Continue reading
