CAD: computer-aided design; CAM: computer-aided manufacturing; inner area = towards the pontic; outer area: mesial/distal areas of the bridge; M: molar; PIB: procera implant bridge; PM: premolar; ROIs: regions of interest; total: average of inner and outer areas.

The PM and M implant surfaces were virtually cut into half resulting in four different areas for fit assessment.
