The influence of zirconia opaquer and thickness of monolithic zirconia on the final shade

HIGHLIGHTS

• What: The aim of this in vitro study is to find out the influence of zirconia opaquer on the optical proportion of monolithic zirconia at different thicknesses. This study shows that applying zirconia opaquer on thin monolithic zirconia (less than 1 mm) over a metal implant abutment can positively influence the final shade by effectively masking the metal background. On this study the authors used monolithic zirconia restoration because it was previously reported that it has a better masking effect thanks to its polycrystalline structure with no glass content which increases opacity so it could mask the . . .
