Primary Outcome Measures

Name	Time	Method
Gingival display	Change from Baseline gingival display, at an average 24 months	Amount of maxillary gingival exposure between inferior border of upper lip and marginal gingiva of maxillary central incisors.

Secondary Outcome Measures

Name	Time	Method
Lip line	Change from Baseline lip line, at an average 24 months	The height of the upper lip relative to the maxillary central incisors.
Lateral negative space	Change from Baseline lateral negative space, at an average 24 months	The buccal corridor between the posterior teeth and the corner of the mouth in smiling.
Smile arc	Change from Baseline smile arc, at an average 24 months	Relationship between a hypothetical curve drawn along The edges of the maxillary anterior teeth and the inner contour of the lower lip in the posed smile.
Smile width	Change from Baseline smile width, at an average 24 months	The distance between the most medial points on the lips at the angles of the mouth (Left to right cheilion, CHR to CHL).
Smile height	Change from Baseline smile height, at an average 24 months	Distance from the most inferior point on the upper lip between the maxillary central inciors to the most superior point on the lower lip on a perpendicular vertical line from the upper point (upper stomion to lower stomion,UST to LST).
