“…The present study was carried out with image analysis performed on panoramic X-rays, even though cone beam computed tomography (CBCT) nowadays represents an exciting new tool for canine impaction diagnosis and treatment planning [29]. According to a recent systematic review [30], CBCT was suggested as more accurate than conventional radiographs in localizing maxillary impacted canine, even though no robust evidence was found to support using CBCT as a first-line imaging method for impacted maxillary canine evaluation, but it is indicated when conventional radiography does not provide sufficient information.…”

Background Even though periodontal health was suggested to be not related to the traction technique, some other variables might influence the esthetic outcome of palatally displaced canines (PDC) when aligned, such as the initial position and impaction rate of the canine before treatment. The purpose of the present study was therefore to evaluate the existing correlations between periodontal health outcome of PDC after their exposure and alignment and their initial position identified according to the different rates of impaction severity. Materials and methods The final sample enrolled 293 PDC which satisfied inclusion and exclusion criteria. All the canines were exposed using CT by the same oral surgeon and orthodontic traction was applied using the easy cuspid device followed by fixed appliance treatment. Image analysis and periodontal status evaluation were performed for all PDCs. Results α -Angle and d -distance showed no significant differences in the periodontal outcome of PDCs after treatment. The only tested variable showing significant differences was S , since canines with CEJ visible at the end of the treatment presented sectors with a mean score of 1.67, which was significantly different ( P < 0.05) when compared to the S -sector for the canines that showed PD < 2 mm at the end of the treatment. Conclusions Radiographic variables as α -Angle and d -distance seem to not influence the periodontal outcome of the treated impacted canine regardless of the amount of gravity. On the contrary, S -sector might play a significant role when higher rates of gravity are present suggesting the possibility in few cases for periodontal damage at the end of treatment.

“…Scientific literature points out that the treatment of transmigrated mandibular canines usually involves a surgical extraction or a radiographic follow-up [6, 7, 11, 15]. Some authors indicate that the orthodontic traction treatment might be possible when the canine is in an angular position, which could be the reason why the Mupparapu type 1 cases are most commonly treated with this modality [16–19].…”

“…Even though lower canine impaction is less common than upper canine impaction, the first type is much more affected by transmigration [5, 8] (approximately 40.4% of mandibular impacted canines) [11]. On the other hand, it is more frequent in women [1, 5, 7, 10, 12, 13].…”

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.

“…The mandibular canines are impacted in approximately 0.1% of cases [15]. In a retrospective study of 94 impacted lower canines, found transmigration in approximately 40.4% of impacted lower canines [16]. However, in some cases, they can occur bilaterally [17].…”

Included teeth are all the dental elements that arrive the normal time of its eruption, remains immersed within the tissues. Usually found when missing a tooth, or on routine radiographic examinations. In the presence of included teeth, it is necessary to define the best treatment approach, whether it is surgical, through exodontia, or by orthodontic tracings. Inclusive canines, in the symphysis region and near the base of the mandible, are rare and make the use of orthodontic traction techniques contraindicated. Presence of teeth in the intraosseous ectopic position can cause injuries, such as alveolodentary ankylosis, calcium metamorphosis of the pulp and aseptic pulp necrosis, among others. Anamnesis, physical examination (intra- and extraoral) and radiographic examinations such as panoramic, periapical, computed tomography, and occlusal radiographs should be performed to make the diagnosis adequate. In general, the success of the treatment depends on the age of the patient and the position of the canines at the time of the surgical procedure. The objective of this work is the extraction of a lower canine with extra-oral access in an outpatient clinical setting under local anesthesia.

Impacted and transmigrated mandibular canines: an analysis of 3D radiographic imaging data

Abstract: Treatment often entails the surgical removal of the canine-especially in cases of transmigration. The findings emphasise the importance of early diagnosis and CT/CBCT imaging for further diagnostics and future research of impacted mandibular canines.
