This excellent manual details the orthodontic solutions possible through the use of the STb light lingual system and its innovative variable-friction lingual bracket. Taking into consideration the recent developments within the industry and in laboratory procedure, the authors detail the latest improvements in the system, such as improved patient comfort, increased predictability of results, shortened treatment times, and decreased laboratory work. Furthermore the biomechanical benefits of the STb system are explained in full, including comprehensive chapters on extractive and nonextractive mechanics, absolute anchorage control, low frictional force, and the lingual straight-wire method. Multiple case presentations highlight the obvious esthetic advantage of using invisible orthodontic therapy, and a separate chapter outlines the keys to successfully managing the esthetically minded patient. An essential tool for all clinicians interested in lingual orthodontics.
