Background and Purpose

2

Transmigrant mandibular canines: a record of 28 cases and a retrospective review of the literature.

Joshi MR Angle Orthod. 2001 Feb;71(1):12-22. Review.

PMID:11211293 [PubMed - indexed for MEDLINE]

Transmigration of mandibular canines across the midline is rare.The patient was asymptomatic.

We considered a canine to be transmigrant when one-half or more of its length was seen

to have crossed the mandibular midline. We based the diagnosis on the clinical findings, particularly on the panoramic radiographs.

Transmigration of mandibular canines: a review of literature and a report of 5 cases.

Camilleri S, Scerri Angle Orthod. 2003 Dec;73(6):753-62. Review. PMID:14719743

[PubMed - indexed for MEDLINE]

The etiology of transmigration is unknown; however, abnormal displacement of

the tooth or deviation during development is the most commonly accepted

explanation.

The migrating canine showed no evidence of resorption or pericoronal

radiographic changes suggestive of cystic degeneration.

Treatment, in part, depends on the canine’s radiographic position and clinical

manifestations.

Double transmigrationd and hyperdontia

Camilleri S.

Angle Orthod. 2007 Jul;77(4):742-4. PMID:17605496 [PubMed – indexed for MEDLINE

Early diagnosis with an orthodontic terapy and

surgical intervention can help dentists preserve the

canines, which play an important role, in both

esthetics and function, in human dentition.

Investigation of transmigrated and impacted maxillary and mandibular canine teeth in an orthodontic patient

population.

The combined surgical- orthodontic treatment of impacted canine has been divided into 3 step:

1) FIRST ORTHODONTIC STEP: preparation of anchorage;

2) SURGICAL STEP: a) localization;

b) surgical exposure;

c) surgical attachment of an orthodontic button or bracket.

3) SECOND OTHODONTIC STEP: a) application of direct traction;

b) orthodontic alignement.

Transmigration of permanent mandibular canines: a case report

Shanmuhasuntharam P, Boon LC.

Aust Dent J. 1991 Jun;36(3):209-13. Review. MID:1877915 [PubMed - indexed for MEDLINE]

Mupparapu proposed a classification of mandibular canine transmigration based on the migratory pattern

and position of the canines in the jaw:

- Type 1: a canine impacted mesio-angularly across the midline, labial or lingual

to the anterior teeth;

- Type 2 :a canine horizontally impacted near the lower border of the mandible

inferior to the apices of the incisors;

- Type 3: a canine erupting on the contralateral side;

- Type 4: a canine horizontally impacted near the inferior border of the opposite

side

- Type 5: a canine positioned vertically in the midline. with the long axis of the tooth crossing

the midline.

Canine transmigration: comprehensive literature review and report of 4 new Australian cases.

Oral Pathology, The University of Queensland, School of Dentistry & UQ Centre for Clinical Research

We diagnosed transmigrant canines on the basis of the clinical and radiological

findings, and we obtained the data from the patients’ case histories and panoramic

radiographs.

Incidence of canine impaction and trasmigration in a patient population

Aydin U, Yilmaz HH, Yildirim D.

Dentomaxillofac Radiol. 2004 May;33(3):164-9. PMID:15371316 [PubMed - indexed for MEDLINE]

- The patient finished treatment with a normal and stable occlusion between the maxillary and

mandibular arches and an adeguate width of attached gingiva;

- All teeth were successfully erupted;

- Transmigration is a rare dental condition that can be treated successfully with a collaborative effort

from several dental disciplines.
