title: Ectopic eruption of transposed mandibular permanent lateral incisors beneath primary first molars. Case report.
abstract: Mandibular permanent lateral incisors showing bilateral transposition and ectopic eruption were seen beneath primary first molars on bitewing radiographs in a female aged 9 years. This report chronicles management of the case during the mixed dentition period. Appropriate space maintenance after extraction of mandibular primary first molars, cuspids and lateral incisors on both sides facilitated eruption and repositioning of the permanent lateral incisors without the need to sever supracrestal gingival fibres.
