Clinical Trial Summary

The aim of the present study is to evaluate the wear of enamel opposed by Newly Introduced Gradient Monolithic Zirconia compared to that of enamel opposed by Full Strength Monolithic Zirconia

Description:

The aim of the present study is to evaluate the wear of enamel opposed by Newly Introduced Gradient Monolithic Zirconia compared to that of enamel opposed by Full Strength Monolithic Zirconia Teeth preparation and impressions, placement and permanent cementation of the final restoration using resin cement, and optical scanning of both the restoration and the opposing tooth. Follow up postoperatively after six and twelve months, and optical scanning of both the restoration and the opposing tooth.
