The permanent maxillary canine has a high incidence of impaction. In the clinical treatment of impaction, the first problem is diagnosis and localization. The new diagnostic 3-dimensional systems shown in this article provide valid support in understanding anatomic connections and planning the movements needed for orthodontic correction. Thus, the clinician can reduce the incidence of iatrogenic damage of adjacent structures. This article reviews several biomedical systems for guided eruption of palatally impacted canines and discusses a new device for guided eruption of the surgically disimpacted tooth. This device, called Easy Cuspid, is designed to reduce recognized problems with reaction forces through a simple method. A clinical case of bilateral impaction of the permanent maxillary canines shows the application of the diagnostic method and the biomechanical system, Easy Cuspid.
