Representative images for gross morphology of the BLANK and GRADIENT groups at 12 weeks postimplantation. The top row represents images from the implants that received the highest morphological score (BLANK, 8; GRADIENT, 8.7). The middle row represents images from the implants that received the mean morphological score (BLANK, 6; GRADIENT, 5.2). The bottom row represents images from the implants that received the lowest morphological score (BLANK, 3.3; GRADIENT, 1.3). The BLANK group performed better in percent defect fill, whereas the GRADIENT group performed better in edge integration with the native tissue. Scale bars: 1 mm.
