Abstract

The current study evaluated the effect of surface finish on the quality of a 3D mesh and carried through to see if the digital carries to fruition in the final milled product; Preparation design was intentionally selected to match a low thickness restoration to test the accuracy of the workflow.
Internal fit:
Evaluation was through silicone index and digital microscopy measurements.
Marginal adaptation:
Analogue and digital testing using digital microscopy and triple scan protocol were used to test each other to eliminate any bias of the results; after scanning of prepared teeth, and two software’s were used to produce the digital components measuring the captured images on a digital microscope and both were tested to see if the measurements are:
1. Comparable to each other in numbers and within the same range
2. Produce any statistically significant difference in both tested variables.

Surface Finish and mesh quality:
Triple scan protocol was used to 3D superimposition the models in the EXOCAD GMBH and Medit package utilizing the reference scan to check if:
1. Digital microscopy results are proportional to each group in the number of triangulations points.
2. Digital microscopy results are consistent with the produced final restoration.
3. All the variables collectively support the hypothesis and proportionate to each other and supporting enhanced workflow.
Both the die and the veneer showed highly significant difference between the three groups. Hence collectively, polished samples showed significantly better results than the blue and yellow group samples.
