Abstract
Patients treated with the excisional new attachment procedure were evaluated 5 yr or more following the procedure. They had received maintenance therapy about 4 times a yr. Clinical measurements of free gingival margin height, pocket depth and width of keratinized gingiva were made from the cemento-enamel junction in 56 surgical sites and compared to the same parameters recorded presurgically and at 1 and 3 yr postsurgically. Probable depths increased slightly and the amount of previously gained new attachment decreased slightly at each postoperative evaluation period. Only isolated sites were the same as or worse than pretreatment levels. An overall mean net gain in clinical attachment of 1.5 mm was found at 5 yr after treatment, and probable depths approached 3.0 mm at this time. These 5 yr findings were statistically and clinically significant improvements over preoperative measurements.
