ECTOPIC ERUPTION OF THE FIRST PERMANENT MOLARS MANAGED WITH TRANSPALATAL ARCH: TWO CASES REPORT

Abstract
Aim
The ectopic eruption of the first permanent molars is a local disorder characterized by the eruption of these teeth apical to the distal undercut of the second deciduous molars. Two different cases diagnosed with an irreversible ectopic eruption of a maxillary first permanent molar and treated with a trans-palatal arch (TPA) are reported.
Cases presentation
The first case of an 8 year-old male presented an irreversible ectopy of the first permanent molar, exacerbated by an hypoplasic maxilla. It was decided to use a TPA to derotate and distalize the first permanent ectopic molar and to perform subsequently serial extractions of the first permanent premolars to recover space in the arch. The second case of another 8 year-old male showed a bilateral ectopy of the maxillarypermanent first molar, with a marked mesial rotation. A similar approach with a TPA to derotate and distalize the two molars was adopted.
Conclusions
In both cases the TPA used to derotate and distalize the first permanent ectopic molars proved to be a valid treatment approach due to its simplicity and effectiveness.
