Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be mean mid-facial recession coverage (mRC) measured as a percentage. Time frame: 6 months and 1 year with an intraoral scanning file (STL) and digital software | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Esthetic score [ Time Frame: 6 months and 1 year ] measured using esthetic score measured using numeric values from 0 to 10 2. Patient-reported esthetics [ Time Frame: 6 months and 1 year ] measured using patient-reported esthetics measured using numeric values from 1 to 5 3. Patient-reported post-operative pain [ Time Frame: 2 weeks ] measured using patient-reported post-operative pain, based on VAS scale, measured as numbers from 0 to 10. 4. Keratinized tissue (KT) gain [ Time Frame: 6 months and 1 year ] measured using KT gain measured in mm with a manual periodontal probe 5. Keratinized tissue thickness (KTT) [ Time Frame: 6 months and 1 year ] measured using KTT gain measured in mm an intraoral scanning file (STL) and digital software 6. Professional-reported esthetics [ Time Frame: 6 months and 1 year ] measured using blinded examiner reported esthetics measured using numeric values from 1 to 5 | — |
