Wear Measurement of Opposing Enamel to Milled Resin Matrix Ceramic Versus Bulk Fill Resin Composite After 2 Years

Intraoral Wear Measurement of Opposing Enamel to Indirect Milled Resin Matrix Ceramic Versus Direct Bulk Fill Resin Composite in Posterior Teeth After Using 2 Years: Randomized Clinical Trial

This clinical trial conducted to measure the amount of wear of opposing enamel to indirect milled resin matrix ceramic versus direct bulk fill resin composite intraorally using Digital Scanner after two years of using

Indirect milled resin matrix ceramic overlay versus direct bulk fill resin composite overlay was utilized in a clinical trial to compare the amount of enamel wear on endodontically treated molars using a Panda P2 digital scanner and Geomagic Control X 3D software. After one and two years, measurements of enamel wear were taken.
