Design outcomes

Primary

MeasureTime frame
Change in the volume of enamel (in microns cubed) measured once the impressions, which are taken at the baseline and de-bond visit, are poured up in stone and scanned by laser profilometer in the laboratory.

Secondary

MeasureTime frame
Roughness (Ra) measured once the impressions, which are taken at the baseline and de-bond visit, are poured up in stone and scanned by laser profilometer in the laboratory.
