Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Soft tissue volume: the amount of contracted connective tissue volume in the recipient area using superimposition of intraoral scanner images in millimeters. Timepoint: Soft tissue volume will examine by intraoral scanner before surgery and three and six months after surgery. Method of measurement: Intraoral scanner (Medit-i500, Korea) is used to examine the volume changes of soft tissue. | — |
Secondary
| Measure | Time frame |
|---|---|
| Keratinized tissue width. Timepoint: It will measure when the patient is selected for admission, three and six months after surgery. Method of measurement: Using a UNC15 probe in millimeters.;Gingival phenotype. Timepoint: Before patient surgery. Method of measurement: Using the UNC15 probe, it will divide into two categories, thin and thick.;Pink esthetic score. Timepoint: Will be measure within six months follow up. Method of measurement: Evaluation of the aesthetic results of the soft tissue around the implant-based crown by considering the mesial and distal papillae, surface and color, contour and texture of the soft tissue and alveolar defects of the process will be done by photographic observation.;The amount of pain. Timepoint: It will check in the first seven days after surgery. Method of measurement: Measure by Visual analog scale.;Number of analgesics consumed. Timepoint: Number of analgesics used from the day of surgery to the time of suturing. Method of measurement: questionnaire.;Thickness of gingiva. Timepoint: Before surgery, three and six months after surgery. Method of measurement: Gingival thickness at 1, 3 and 5 mm from the margin line connecting the surrounding teeth before surgery and at 1, 3 and 5 mm from the implant prosthesis margin, three and six months after surgery. | — |
