One-step surgery and correction of the transverse dimension of the maxilla using the lingual technique: An original assisted transverse surgery method

During orthodontic-surgical treatment, orthodontics must facilitate the surgery, and vice-versa. More specifically, surgical adjustment of the transverse dimension of the maxilla and its vertical and/or anteroposterior repositioning require orthodontic support. In addition to the orthodontic appliance, a palatal device is needed to guide and maintain the correction. In the lingual technique, this situation might appear to be difficult to manage since both the appliance and the auxiliaries are located on the same side. We demonstrate a removable tooth-supported expander as well as the use of dua-insertion palatal bands to solve a transverse maxillary deficit less than or equal to 5 mm.
