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

Study Overview
=================
Brief Summary
-----------------
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

Detailed Description
-----------------
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

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Adhesive resin cement<br>type of cement used for cementation of crowns have a good adhesion bond | Diagnostic Test: improved patient satisfaction ,marginal integrity, shade match and gingival health<br>* For both groups N.Awill make a recall visit after6 months and after 12 months: Patient satisfaction will be performed according to questionnaire after One year.Questionnaire will contain several questions that evaluate patient satisfaction. The color will be measured using spectrophotometer Vita easy shade in the same delivery visit ,after 6months and after one year . Images will be captured using digital handheld light microscope (Celestron 5 Megapixel Resolution, USA) that is fixed on a film holder on a specific distance for the standardization of all the images will be captured by the microscope for all the patients.(22) Images will be analyzed using imageJ software to measure marginal gap. Gingival health will be measured using G<br>|
