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

Not Applicable

• Conditions: Hybrid Crowns on Single Implants in Esthetic Zone
• Interventions: Other: Vita Enamic hybrid crown; Other: emax hybrid crown

• Registration Number: NCT03333889
• Lead Sponsor: Cairo University

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?
