Details and patient eligibility

About

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?
