Abstract
Segmental distraction osteogenesis of the anterior alveolar process is a sufficient method to enlarge the alveolar arch. Indications for this method are dental crowding, retroalveolism, and leveling of the curve of Spee. However, after the distraction period, the anterior alveolar segment often shows an unfavorable inclination resulting in nonphysiologic load on the lower incisors.The aim of this paper was to introduce a new approach in segmental distraction osteogenesis of the anterior alveolar process. This new method combines 2 different surgical techniques: a segmental osteotomy for the alveolar ridge with instant fixation in the desired position and a distraction procedure for the alveolar segment. This hybrid distraction avoids an unfavorable inclination of the lower incisors after front-block distraction procedures.
