Longitudinal evaluation of free autogenous gingival grafts. A four year report.
This ongoing study was designed to determine the necessity for and effectiveness of the free autogenous graft in maintaining periodontal attachment. Four-year data are presented for 42 patients who initially had bilateral surfaces with inadequate attached keratinized gingiva including 22 patients who began with bilateral areas of recession and no attached gingiva. In both populations a free autogenous gingival graft was placed on one side and the contralateral side was treated by scaling and root planing to serve as the control. The results indicate that plaque and gingival indices significantly decreased over 4 years on both experimental (grafted) and control (nongrafted) sides. Neither side had further attachment loss but the grafted side showed "creeping" attachment with a concomitant decrease in recession. This study would indicate that facial gingival units with minimal or no attached keratinized gingiva can maintain attachment levels when inflammation is controlled.
