COMPARISON OF MUCOGINGIVAL CHANGES FOLLOWING TREATMENT WITH CORONALLYPOSITIONED FLAP AND GUIDED TISSUE REGENERATION PROCEDURES

This study compared the variation in anatomic width of the mucogingiva l unit following coronally positioned flap or guided tissue regenerati on procedures in deep (greater than or equal to 4 mm) buccal maxillary gingival recession defects 12 months postsurgery. Eighteen patients, 10 treated with guided tissue regeneration procedures and eight treate d with coronally positioned flap procedures, were retrospectively anal yzed. The results demonstrated that both treatments led to consistent recession depth reduction and coronal shift of the mucogingival juncti on. A significant increase in the amount of keratinized gingiva was ob served for the guided tissue regeneration procedure, but a decrease th at was not statistically significant was observed for the coronally po sitioned flap procedure.
