Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gingival display	Amount of maxillary gingival exposure between inferior border of upper lip and marginal gingiva of maxillary central incisors.	Change from Baseline gingival display, at an average 24 months
Secondary	Lateral negative space	The buccal corridor between the posterior teeth and the corner of the mouth in smiling.	Change from Baseline lateral negative space, at an average 24 months
Secondary	Smile arc	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.	Change from Baseline smile arc, at an average 24 months
Secondary	Lip line	The height of the upper lip relative to the maxillary central incisors.	Change from Baseline lip line, at an average 24 months
Secondary	Smile width	The distance between the most medial points on the lips at the angles of the mouth (Left to right cheilion, CHR to CHL).	Change from Baseline smile width, at an average 24 months
Secondary	Smile height	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).	Change from Baseline smile height, at an average 24 months
