Reconstruction of Interimplant Papilla by Demineralized Freeze-dried Bone Allograft Block Fixed by Titanium Screw in Maxillary Esthetic Zone

To evaluate effectiveness of demineralized freeze-dried bone allograft (DFDBA) block fixed by titanium screw for reconstructing interimplant papilla in maxillary esthetic zone during one-stage early loading multiple implant procedure. A total of 20 implants were placed in 10 systemically healthy patients (2 implants per patient) for replacement of multiple teeth by early loading one-stage implants along with interimplant papilla reconstruction using DFDBA block fixed by titanium screw. At the baseline, 6 months, and at 1 year, clinical measurements (interimplant papillary height measurement, papilla contour) and radiographic measurements were recorded. At 1 year, mean gain in interimplant vertical crestal bone was 1.7 mm, and complete reconstruction of the papilla was observed in 90% cases. Demineralized freeze-dried bone allograft block fixed by titanium screw for reconstruction of interimplant papilla in maxillary esthetic zone during one-stage early loading multiple implant procedure is effective. Presence of interimplant papilla is of utmost importance for esthetically successful implant-supported restoration in the anterior region. This technique leads to reconstruction of interimplant papilla, thus providing esthetic appearance.
