Orthodontic Treatment of Bilateral Impacted Mandibular Canines and a Mupparapu Type 2 Transmigration

الملخص EN

Dental transmigration is a rare condition that mainly affects the mandibular canines.

Since the tooth involved is usually impacted and its crown has crossed the midline towards the opposite side, the treatment options frequently are surgical removal or radiographic follow-up, and, in some cases, orthodontic traction is possible.

In 2002, Mupparapu presented a classification for lower canines in transmigration according to their position within the mandible.

This paper is aimed at describing the orthodontic treatment of a female patient with two impacted mandibular canines, one of them in a Mupparapu type 2 transmigration position (horizontal impaction position near the lower mandibular border and below the incisors’ root apices).

Additionally, the paper discusses the biomechanical orthodontic design and the alternative treatment options for these complex cases.
