Histological samples (a) Illustration of defect analysis. Blue box depicting regions of interest in the buccal and lingual sides, yellow = bone, grey = TiO2 scaffold. b Vertical linear measurements from the implant top (green line) to the first bone contact at the implant surface (blue line) and 0.5 mm lateral to the implant (yellow line). c Horizontal linear measurements from implant surface to the first bone contact. Measured from implant top and five consecutive millimetres apically. Lingual side left and buccal side right for all figures
