The operated area will be cleaner without dressing and will heal faster. The flap procedures on the palatal aspect require a different approach as compared to other areas because the palatal tissue is composed of a dense collagenous fiber network and there is no movable mucosa on the palatal aspect. This wedge of tissue contains most of the inflamed and granulomatous areas that constitute the lateral wall of the pocket as well as the junctional epithelium and the connective tissue fibers that still persist between the bottom of the pocket and the crest of the bone. To perform this technique without creating a mucogingival problem it should be determined that enough attached gingiva will remain after after removal of pocket wall. The apically displaced flap provides accessibility and eliminates the pocket, but it does the latter by apically positioning the soft-tissue wall of the pocket.2 Therefore, it preserves or increases the width of the attached gingiva by transforming the previously unattached keratinized pocket wall into attached tissue. 2.

Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap with or without resective osseous surgery, and orthodontic forced eruption with or without fibrotomy have been proposed for clinical crown lengthening. Dentocrates To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. Following are the steps followed during this procedure. It must be noted that if there is no significant bleeding and flaps are closely adapted, periodontal dressing is not required.
