Each patient’s orthodontic treatment is different and requires a customized treatment plan based on a complete diagnosis. X-rays, dental impressions, and photographs help the doctors make a decision on which treatment approach will bring each patient the best results. Orthodontic appliances may be fixed or removable. They may be made of metal, ceramic, or aligner material. All orthodontic appliances have one purpose: use gentle pressure to move teeth and jaws into their proper positions.
