Abstract
The maxillary canine comes after the third molar as the most frequently included tooth. The prevalence of maxillary canine impact is 0.8%–2.8%. Buccally included canines represent a minority of cases, approximately 15%–32% of the cases depending on the authors. The placement in the arch is often more complex due to periodontal considerations, the frequent proximity of the lateral incisor root and the very precise control of the direction of the tension to be delivered by the device. In this clinical case, the combination of two innovative techniques—submerged temporary anchorage device and customized lingual device—made it possible to decrease both the complexity of the treatment for the practitioner and the constraints for the patient.
Highlights
Orthodontists are frequently confronted with the late discovery of included canines
Obtaining the position of the upper vestibular canines is a challenge for orthodontists who must decide between the risk of altering the lateral incisor root, which is linked to too much vertical traction and the periodontal risk linked to an excessive vestibular traction
The lingual device “Win” was chosen for its small size and how easy it is to control the anterior torque on the canine slope during the insertion of a vertical “Edgewise ribbon” arch in vertical grooves very close to the palatal surface of the teeth[9]
