Bone Regeneration of Peri-Implant Defects Using a Collagen Membrane as a Carrier for Recombinant Human Bone Morphogenetic Protein-2

Schematic configuration of the TAV (mm³). (a) The lower border of the TAV was located 3 mm below the implant platform. The coronal border was defined by the most-coronal location of radiopaque tissue. The buccolingual extension of the TAV ranged from the center of the implant to the most-buccal radiopaque tissue (at an angle of 90° to the implant surface). (b) The mesiodistal borders of the TAV were confined by vertical lines 7 mm from the center of the implant surface. The implant itself was excluded from the TAV. P, implant platform.
