Clinical data were evaluated before (T0), immediately after (T1), 3\u2009months after (T2), 6\u2009months after (T3) and 1\u2009year after (T4) FGG placement.

The buccal KMW gain and shrinkage rate in the FFFs group were not statistically significant compared with the IBFs group at T4. In the IBFs group, the buccal KMW gain and shrinkage rate remained relatively stable after 6\u2009months. The lingual KMW gain in the FFFs group was significantly greater than that in the IBFs group at T4 (2.1\u2009\u00b1\u20090.2\u2009mm vs. 1.5\u2009\u00b1\u20090.2\u2009mm,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).
