All shades of Neo Spectra™ ST flow composite restorative are radio-opaque, with a 1 mm radio-
opacity equivalent to 1.8 mm radio-opacity of aluminum. Aluminum has a radio-opacity equivalent
to that of dentin. Thus 1 mm of material having a radio-opacity equivalent to 1 mm of aluminum has
a radio-opacity equivalent to that of dentin.
3.2 Cementation of light transmissible indirect restorations
I. Following removal of the temporary restoration and any remaining temporary cement, clean
enamel and dentin as directed by the adhesive manufacturer's directions.
II. Check the fit and esthetics of the restoration. Technique Tip: Occlusal adjustment of veneers and
