The coronally advanced flap (CAF), either by itself or combined with other soft tissue grafts, provides predictable root coverage. However, it is a major challenge to suture and secure the flap coronally and stabilize its position over the entire healing period. Thus, the purpose of this study was to introduce a modified incision design and a suturing technique (sling and tag [SAT]) to enhance the results of CAF for root coverage. Ten patients with Miller Class I gingival recession defects (>= 2.5 mm) were treated. Clinical parameters assessed included recession depth (RD), recession width (RW), clinical attachment level (CAL), probing depth (PD), gingival tissue thickness (GT), and keratinized gingiva width (KGW). Measurements were taken at baseline and 6 months and 1 year later. The paired t test was used to compare presurgical and postsurgical results. Statistically significant (P < .05) reductions in RD (2.6 ± 0.5 mm) and RW (2.9 ± 0.9 mm) were observed at 1 year. An average of 93.0% ± 14.8% root coverage was achieved. In addition, a statistically significant CAL gain of 3.3 ± 1.0 mm was obtained. No statistically significant differences were found in PD and KGW before and after therapy. The newly introduced flap design and SAT suturing technique may enhance the results of CAF for root coverage.
