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 & Interventions
E-max hybrid crown
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
Intervention: emax hybrid crown (Other)
Vita Enamic hybrid crown
Vita Enamic hybrid crown polymer infilltrated ceramic network(hybrid ceramic) characterized by low modulus of elasticity that acts as cushion on implants.
Intervention: Vita Enamic hybrid crown (Other)
