Figure 6.
Descriptive statistics of mean differences between various ROIs in both cast superstructure (CAST) and CAD-/CAM-manufactured restoration (PIB).
The fit assessment (mean distances between implants and superstructure) clearly shows the three-dimensional distortion of the cast superstructures (CAST) towards the pontic area in both the PM and M areas of the restoration, while the CAD-/CAM-manufactured superstructure (PIB) revealed equal circumferential fit.
CAD/CAM: computer-aided design/computer-aided manufacturing; PM: premolar; M: molar; PIB: procera implant bridge.
Description of areas investigated: inner area = towards the pontic; outer area = mesial and distal areas of the bridge; total = average inner and outer areas.
