Which procedure is performed to ensure proper fitting of orthodontic appliances?

The procedure that ensures the proper fitting of orthodontic appliances is taking dental impressions. Dental impressions capture a precise mold of a patient's teeth and their occlusion, which is critical in creating orthodontic appliances that fit accurately and comfortably. These impressions allow orthodontists to design aligners, retainers, or other appliances tailored to the patient's unique dental structure.

While adjustments to brackets, placement of bands, and removal of excess bonding material are important steps in the orthodontic process, they are typically performed after the initial impressions have been made and the appliances have been fabricated. The impressions are the foundational first step that provides the necessary information for accurate appliance construction, ensuring the overall effectiveness and comfort of the orthodontic treatment.
