Injectable Platelet-Rich Fibrin and Microneedling For Papillae Reconstruction In Esthetic Zone

First, MN will be done in the required area with insulin syringe gauge 30,The interdental papilla will vertically and horizontally measured in mm. By establishing a ratio and proportion, the number of microchannels in the region to be treated will calculated to be 250 microchannels per square cm Then, a venous blood sample will be taken for each patient using a 10-ml injector into i-PRF tube containing no anticoagulant and centrifuged at room temperature for 3 min at 700 rpm (60 g force). The 30-gauge dental injector needles will be used for injection of i-PRF. The needle will be inserted at 45° angle, 2-3-mm apical to the involved papilla and all surrounding areas will receive iPRF. Each involved papilla will be injected with an amount till blanching is visible . This method will be repeated for 4 times at 10 days intervals consecutively.
