Patient Satisfaction ,Marginal Integrity ,Shade Matching and Gingival Health of Zirconia Reinforced Lithium Silicate Bridges Cemented Using Bioactive Cement and Adhesive Resin Cement

Bioactive cement have been introduced recently into the market according to the manufacture it is assumed that it stimulates mineral apatite formation and the natural remineralization process at the material-tooth interface that knits together the restoration and the tooth, penetrates and fills micro-gaps, reduces sensitivity, guards against secondary caries, and seals margins against microleakage

To evaluate the cement type (bioactive cement and adhesive resin cement ) on Patient satisfaction ,marginal integrity ,shade matching and gingival health of cemented zirconia reinforced lithium silicate restoration .

PICOTS:

P: patients with missing anterior teeth that needs fixed restoration . I: Bioactive cement. C: adhesive resin cement. O: patient satisfaction ,margin integrity ,shade matching and gingival health T: 1 year
