Abstract
ABSTRACT 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.
Highlights
Transmigration is the pre-eruptive intraosseous migration of a tooth, crossing the mandibular midline [1]
Canine migration most frequently occurs in the mesial direction, crossing the mandibular symphysis by lodging on the opposite side of the arcade [10]
Lower impacted canines are less common than impacted third molars, maxillary canines, and mandibular premolars [13,14]
Summary
Transmigration is the pre-eruptive intraosseous migration of a tooth, crossing the mandibular midline [1]. Transmigrations are usually asymptomatic and discovered during routine radiographic orthodontic examinations [1]. They may cause neuralgic symptoms [4] and can be reabsorbed by root pressure or inclination of adjacent teeth [5], or migrate to adjacent structures such as the coronoid process [6], causing pain and discomfort to the patient. Type 2: canine horizontally impacted near the lower border of the mandible, below the apex of the incisors. Type 4: Canine horizontally impacted near the lower border of the mandible, below the apexes of premolars or molars on the opposite side. Type 5: Canine positioned vertically in the midline (the long axis of the tooth crossing the midline) regardless of the eruption state [7]
