Linear soft tissues contour measurements
The linear increase in buccal soft tissue contour thickness at the level of the mucosal margin was greater in the test (1.96 ± 2.69 mm) than in the control group (0.65 ± 0.42 mm), although this difference was not statistically significant. Two mm apically to the buccal mucosal margin, the increase was minimal and similar in both groups (Table Linear soft tissues contour changes at 12-month follow-up in millimeters. (GM, gingival margin)
