Surgical Extraction of palatally Impacted canine

When the impacted tooth is positioned palatally the approach is achieved using a bilateral palatal flap. The incision for creation of the flap begins at the first or second ipsilateral premolar and, after continuing along the cervical lines of the teeth, ends at the first premolar on the contralateral side After careful reflection of the mucoperiosteum, part of the crown of the tooth may be exposed, or the entire crown may be covered by bone, resulting in protuberance at that site Either way, enough bone must be removed to expose the entire crown, so that the tooth may be extracted using forceps or an elevator If the tip of the crown is positioned between the roots of the lateral and central incisors, there is a risk of injuring their roots during the exposure attempt. That is why extraction of the canine must be achieved using the technique of separating the crown from the root. More specifically, a groove is created on the cervical line of the tooth using a fissure bur and, after placing the elevator blade in the groove created, the instrument is rotated until the crown is separated from the root The crown is then removed, and, after using the round bur to create a purchase point on the root for placement of the angled elevator’s tip, the root is elevated from its bed or using straight elevator between the root and adjacent bone in wedge and levering action with extreme caution After this procedure, the bone edges are smoothed, and the area is thoroughly irrigated with saline solution, while the flap is repositioned and sutured with interrupted sutures
