Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| Lip line | Change from Baseline lip line, at an average 24 months | The height of the upper lip relative to the maxillary central incisors. |
| 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). |
