Bridges Dear ECO Community Members Everyone at EAD is excited to bring you the latest version of our EAD Dentist system software This version 4 6 software update is a direct response to your requests hope you ll agree that it provides even more capabilities and practical opportunities to use your EAD system for greater satisfaction for you your team and your patients Your 4 6 update features bridges Scanning designing and milling bridges chairside Plus new materials are coming out over the upcoming weeks to be able to take advantage of the advanced software solutions including Telio CAD from Ivoclar Vivadent long term provisional block in 40 and 55 mm sizes new sizes of IPS e max 16 mm longer anteriors and 32 mm anterior bridges and Zirlux FC2 a full contour zirconia single unit for now bridge block in the works Zirconia restorations require additional hardware sintering oven for final processing but your Henry Schein Zahn and lvoclar Vivadent representatives can inform you of the options Enjoy your EAD 4 6 experience Gary Severance DDS Chief Marketing Officer EAD Technologies 2 E4D CAD CAM System Version 4 6 EDU1079 A Table of Contents BIOS uicissim wai tibl Ra M mc ww drin Mn uM TURCA Rei DR 4 BGS Peal acl Ol ne dE DO edd bibi DRE RENE ODE nea ietnnseaeraar nts iat 4 Updated Block Recommendation Ch arT 1 ecce eere ee er uu uuuuuuuuuuauuuauauaRaRRRRRRRRERSERSESESESESESESSESESERERER 4
