Interarch Traction Strategy for Palatal Cuspid Impactions

J Contemp Dent Pract. 2020 Dec 1;21(12):1408-1411.

Abstract

Aim and objective: To disimpact a palatally impacted canine using a novel, compliance-dependent technique.

Background: Orthodontic traction of palatally impacted teeth warrants careful mechanical strategies to avoid complications that include r oot damage to adjacent teeth and r esorptions. Sound biomechanical control to avoid these side effects is considered paramount in planning the traction.

Technique: The palatally impacted canine was pulled into the arch with the aid of a modified power arm on the exposed canine and a miniscrew on the lower arch.

Conclusion: The impacted canine was successfully brought into occlusion within 11 months.

Clinical significance: This paper highlights the use of a simple strategy using interarch mechanics and temporary anchorage devices (TADs) to aid in the safe mechanical eruption of impacted palatal canines without the need to bend complex wire designs.
