Segmental repositioning combined with orthodontic fine adjustment of nonerupting permanent molars: A case report
Kang, Yoon-Goo / Kim, Ji-Young / Lee, Young-Jun / Lee, Baek-Soo
Eruption disturbance of a permanent tooth is challenging to clinicians. Eruption failure of a posterior tooth causes lateral open bite that severely interrupts function. This case report describes the treatment of nonerupting permanent molars by segmental repositioning followed by orthodontic fine adjustment. Two nonerupting permanent molars at different eruption stages were repositioned with a one- or two-step single-tooth segmental osteotomy technique. Final location of the repositioned tooth-alveolar bone segment was adjusted via orthodontic means.
