Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Difference in accuracy of both guides | 6 months | Evaluation of the degree of matching of the post operative actual gingival zenith points with the virtual predicted presurgical plan. Intraoral digital scanning for both groups will be obtained preoperative, immediately after surgery, and follow up appointments at 6 weeks and 6 months after surgery and exported in STL file format then it will be superimposed on the digitally designed diagnostic STL file to obtain statistical differences.The accuracy can be measured by comparing the planned surgery and the actual result of the surgery Linear measurement in millimeters. |
| Secondary | Bone level accuracy | 6 months | The accuracy can be measured by comparing the planned surgical ostectomy level on the CBCT (cone beam computed tomography) and the actual result of the surgery by Linear measurement in millimeters. |
| Secondary | Gingival margin stability | 6 Months | The position of gingival margin in relation to a reference point will be evaluated with linear measurements in millimeters. |
| Secondary | Pink Esthetic Score | 6 months | The \*\*Pink Esthetic Score evaluates seven variables of soft-tissue esthetics. 1)Mesial and distal papillae are scored as missing (0), incomplete (1), or complete (2). 2)Tissue contour is rated as unnatural (0), virtually natural (1), or natural (2). 3)Gingival level is scored according to the discrepancy from the reference tooth: \>2 mm (0), 1-2 mm (1), or \<1 mm (2). 4)Alveolar process, color, and texture are each scored (0),(1) and (2), depending on whether there is a (0)clear difference, (1)slight difference, or (2)no difference. Higher scores indicate better esthetic outcomes with a maximum total score of 14. |
| Secondary | Surgical time | time of the surgery | The time needed to complete each procedure will be calculated in minutes by using a stopwatch from the time of the first incision till removal of the guide. |
| Secondary | Patient satisfaction | 2 weeks | Patient satisfaction was assessed using three direct questions previously applied in Kiyak et al.14: * "Considering this was an elective operation, how likely would you be to recommend it to others?". * "If you had to make the decision again, how likely would you be to undergo this surgery?". * "Considering everything, how satisfied are you with the outcomes of your surgery?". Responses were recorded using a seven-point Likert scale ranging from 1 (not at all likely or not satisfied) to 7 (very likely or very satisfied). |
| Secondary | analgesics | 2 weeks | number of analgesics the patient took after the surgery till the day of sutures removal |
