Abstract: When an impacted maxillary canine is present, it often presents challenges in diagnosis, localization, and management.Mandibular canine impaction is less than half as likely to occur than maxillary canine impaction, and of the patients who belong to the latter group, 8% have bilateral impaction.1 About two-thirds of the impactions are located palatally, while one-third are set buccally.2,3 Therefore, the literature is abundant in studies that investigated maxillary impacted canines.Buccal canine impaction is considered a result of crowding.Jacoby had evidence to support that only 17% of buccal impactions have adequate eruption space, compared to 85% for palatal impactions.Nonetheless, with sufficient space and time, buccally impacted canines will typically erupt.4 Two major theories were proposed to be associated with palatally impacted maxillary canines.The A thorough clinical and radiographical assessment of an impacted maxillary canine's location forms the basis for proper diagnosis and successful treatment outcomes.Implementing a correct biomechanical approach for directing force application primarily relies on its precise localization.Poor biomechanical planning can resorb the roots of adjacent teeth and result in poor periodontal outcomes of the canine that has been disimpacted.Furthermore, treatment success and time strongly rely on an accurate assessment of the severity of impaction, which depends on its 3D spatial location.The evolution of cone-beam computed tomography (CBCT) radiographs provides more detailed information regarding the location of the impacted canines.In addition, the literature has shown that CBCT imaging has enhanced the quality of diagnosis and treatment planning by obtaining a more precise localization of impacted canines.This review article highlights current evidence regarding comprehensive evaluation of three-dimensional orientations of impacted canines on CBCT images for precise diagnosis and treatment planning.
