Clinical Research Directory

1. Full history with clinical and radiographic examination (CBCT) to aid in patient's selection. 2. Supra- and sub-gingival debridement. 3. Oral hygiene instructions (OHI) 4. Presurgical intraoral scanning using an intraoral scanner (IOS) 5. Fabrication of the Gingivectomy guide: * Convert (DICOM) file to STL file then merged to STL file corresponding oral soft tissues 3D data obtained by IOS using software of surgical planning. * Digital waxing up with new desired positions of gingival margins and zenith points performed. * Designing Gingivectomy guide then exported to a 3D printer and mill a transparent resin gingivectomy guide. 6. Surgical Procedure: anesthetized the patient using local anesthesia, Surgical incision using 15c blade following CEJ anatomy will be made at each tooth using the Gingivectomy guide as reference to new gingival level and being careful to preserve the gingival papillae without involving the palatal surfaces. 7. Postoperative care

Gingivectomy guide fabrication: * Impressions and casts obtained. * Waxing-up included new positions of gingival margins and zenith points. * Silicone index with condensation silicone impression materials made with pressure on the cast to reproduce the details of the wax, then filled after setting with resin material and placed in the patient's mouth. * Resin mock-up trimmed with blade to define the correct new gingival level. * After the patient accept the mock-up design will used as Gingivectomy guide. 4.
