The Effect of Surgical Technique on PDC

"* A mucoperiosteal palatal flap is elevated off the bone from the premolar to the midline~* The bone covering the crown aspect of the canine is removed until the largest diameter of the crown is exposed~* Follicular tissue is removed from the exposed crown area~* The flap is repositioned back and sutured~* The area over the exposed canine crown is excised leaving a window with the crown uncovered.~* If the tooth is deeply embedded in the bone, a dressing is placed over the uncovered crown and kept in place with sutures.~* The extraction of the primary canine (if present) is made before or in connection with the surgical exposure.~* Ten to fifteen days later the dressing and sutures are removed and the tooth is left to erupt autonomously.~* When the canine has spontaneously erupted above the palatal mucosa an attachment is bonded to the crown and the canine is moved into alignment in the dental arch above the mucosa with orthodontic appliances."

"* A mucoperiosteal palatal flap is elevated off the bone from the premolar to the midline~* The bone covering the crown aspect of the canine is removed until the largest diameter of the crown is exposed.~* Follicular tissue is removed from the exposed crown area.~* An attachment with a chain is bonded to the exposed canine crown.~* The flap is repositioned back and sutured to cover the exposed crown leaving the chain through the palatal mucosa free in the oral cavity~* The extraction of the primary canine (if present) made before or in connection with the surgical exposure~* Ten to fifteen days later the sutures are removed.~* Within days, traction is applied to the canine with orthodontic appliances by means of the chain, and the canine is pulled through the palatal mucosa out to the oral cavity and into alignment in the dental arch."
