The process is computerized, leaving less room for human error. Dr. Gaertner will submit all the necessary materials for the trays to be created, a process that occurs in a dental laboratory with the help of a team of experts. Patients will receive all their clear aligners at once, and they will be marked accordingly for when they should be worn. A new tray has to be worn every two weeks. Dr. Gaertner will affix bumps to the teeth, which serve as resistance points for the aligners. At some point, Dr. Gaertner will address the patient's bite to ensure this is properly corrected. After approximately 12 months, the teeth will typically be in proper alignment.
