Patient Satisfaction and Crestal Bone Loss of Polymer Infiltrated Ceramic Network Versus Lithium Disilicate Implant Hybrid Abutment Crowns in Esthetic Zone

Study Overview
=================
Brief Summary
-----------------
P: Population: Patients requiring single unit implant restoration in esthetic zone I: Intervention: Polymer-infiltrated-ceramic-network abutment crown (VITA Enamic-VITA Zahnfabrik) C: Comparison: Lithium disilicate ceramic abutment crown (IPS e. max-Ivoclar Vivadent) O: Outcome: patient satisfaction , crestal bone loss and periodontal parameters T: Time: 12 months S :Randomized controlled trial research question:For patients receiving implants in esthetic zone, Does the use of polymer-infiltrated-ceramic-network hybrid abutment crown offer better patient satisfaction , less bone loss and better peri-implant clinical parameters when compared to lithium disilicate hybrid abutment crowns?

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: E-max hybrid crown<br>E-max hybrid crown Lithium Disilicate based ceramic which is characterized by high strength and optimum esthetics and considered a gold standard in anterior restorations | Other: emax hybrid crown<br>* high srength glass ceramic that can be milled in sections up to 1mm .<br>|
| Experimental: Vita Enamic hybrid crown<br>Vita Enamic hybrid crown polymer infilltrated ceramic network(hybrid ceramic) characterized by low modulus of elasticity that acts as cushion on implants. | Other: Vita Enamic hybrid crown<br>* hybrid ceramic material in the form of mesoblocks where the ceramic block is attached to a ti base .The whole assembly is screw retained superstructure.<br>|
