Miniscrew-supported pole technique: Surgical-orthodontic approach for impacted or retained second molars in adolescents

Abstract

Background: Several treatment options have been proposed for the treatment of eruption disturbances of permanent molars. Despite being an infrequent condition, these disturbances should be solved as they can lead to important complications and play a relevant role in completing the occlusion.

Findings: The presented cases involved maxillary and mandibular included second molars (M2s) respectively. Both teeth erupted successfully after the application of the miniscrew-supported pole technique, and a functional occlusion was established.

Conclusions: This technique is a surgically assisted orthodontic procedure performed to force the eruption of impacted/retained M2s. This device uses one mesial miniscrew which allows the application of relevant force to achieve the eruption of complicated retained/impacted M2s within a short period of time.
