摘要
This report describes the two-phase orthodontic treatment of a 7-year-, 6-month-old girl who presented with bilateral gemination of the central incisors. The left side demonstrated a complete gemination, resulting in two separate teeth (#9 and #9a). On the right side the gemination was incomplete, resulting in a large tooth mass (#8) that was 11.5 mm wide with a large pulp chamber and two apices. The tooth mass was extracted and the left central incisor (#9) was successfully moved across the midline (through the midpalatal suture area). The supernumerary incisor (#9a) was then used in the upper left central incisor area. (Angle Orthod. 201181:341-349.)
