| 520 | _aThe aim of this in-vitro study was to evaluate the vertical marginal gap distance and internal adaptation between e max supestracturs and e max hybrid abutments constructed by CAD/CAM and heat pressing techniques.14 Dummy implants were placed in epoxy resin blocks using paralleling device then titanium bases were screwed to the dummy implants.The samples were randomly assigned into two study groups (n=7) for each group according to the construction technique; Group I: e.max CAD/CAM fabricated hybrid abutments and superstructures ,Group II: e-max heat pressing fabricated hybrid abutments and superstructures . For the CAD/CAM group , the titanium base was scannedand the abutment was designed on the DWOS software then milled on a 5 axis machine. For the heat pressing group, wax pattens were fabricated by CAD /CAM technique using CAD wax disck.The wax patterns were then invested and pressed from e max press ingots.The produced cermic abutments of both groups were evaluated on theircrospondingtitanum bases then cemented to it using adhesive resin cement . All Superstrucures were designed as monolithic upper fristpremolar,half of which were fabricated by the CAD/CAM technique and the other half by the heat pressing technique | ||
