Data view software (VGStudio Max v 3.1, Volum graphics, Heidelberg, Germany), and also the sagittal slices were isolated in the reconstructed photos. Before performing the definitive measurements on the test samples, the measuring device (nano-CT equipment with computer software) was calibrated for precision and accuracy by analyzing the technique error. A single abutment-crown sample was scanned 5 occasions consecutively without having removing it from the target platform and by retaining in the identical position inside the nano-CT machine. Marginal gap measurements had been performed on corresponding sagittal sections of all the five virtual models to determine the differences between the repeated scans at set areas. The discrepancies located were beneath five microns involving the various 3D models. The trueness of the device was then assessed using a ball-bar CT scan artifact, in relation for the values obtained making use of a scientific digital caliper and co-ordinate measuring machine (CMM) various occasions. The deviations had been below ten microns. The accuracy in the nano-CT system was located to be within FigureFigure 3.

In in the six bucco-lingual and mesio-distal slices, 10 places were chosen for measurement of marginal and internal fit [26,28,39]. AMD and MG have been evaluated at the crown-abutment margin areas according to the approach suggested by Holmes et al. and applied by a number of other research [28,31,34] (Figure 4). Gaps have been recorded at 4 places on the axial wall, 4 places on the occlusal wall, and two places around the margins denotingbucco-lingual sagittal sections employed for crown marginal and internal gap evaluation, represented by blue and red dotted lines.
