Zones and regions of interest (ROI) for particle count measurement defined for study purposes. Three zones (red dash-line) were selected at 1 mm and 4 mm from the collar and at 2 mm from the apex each. For each zone, two ROIs (blue rectangle) were analyzed at opposite sides of the implant (6 ROIs per implant).
