Within the limits of this study, no difference could be found between subepithelial connective tissue graft and GTR with a bioabsorbable membrane with regard to root coverage, but the GTR technique did not increase the height of keratinized tissue and displaced the mucogingival junction more coronally at 6 months.

Our findings suggest that the maximum available tissue graft as measured in the palatal vault was large enough to allow a safe withdrawal from this donor site in a high percentage of our patient population free of periodontal disease.

Under non-experimental conditions, root coverage procedures are effective. Smoking, maxillary teeth, donor site, and Miller's Classes are prognostic factors that may affect the results.
