[Means of localization of impacted canines: new update].

Canine impaction is a phenomenon enough current in dental practice. It can have more or less complex consequences. The management of impacted canine requires accurate knowledge of its exact position in three-dimensional space. Indeed, authors report very different locations (palatal position between 50 and 85%). At our disposal clinical means and conventional and digital radiological investigations each have their own advantages and disadvantages. With the multitude of ways of localization, practitioners must be able to prescribe the most "targeted" investigation ever. This is prerequisite for any successful orthodontic therapy and/or surgery. This work intends to review different clinical and radiographic investigations available and discuss their relevance in terms of location accuracy of the impacted canine.
