Patient Satisfaction and Peri-Implant Tissue Success of Hybrid Ceramic Versus E-Max Superstructures

Esthetic Patient Satisfaction and Peri-Implant Tissue Success of Crystal Ultra Hybrid Ceramic Compared to E-Max Superstructures in Esthetic Zone

In patients receiving implants in the esthetic zone, would the use of new Nano hybrid ceramic crown material (Crystal Ultra) improve esthetic patient satisfaction and peri-implant tissue success when compared with Lithium Disilicate crown (E-max)?

The patient will be treated in visits designated as follows:

Visit 1: Preoperative records, face-to-face adherence reminder session, signing consents, clinical, radiographic examination and primary impression for diagnostic cast construction.

Visit 2: (first stage surgery): implant placement surgical procedure and postoperative radiograph.

Visit 3: After 3months (second stage surgery): re-opening of surgical site, placement of healing abutments and temporary crowns.

Visit 4: After 2 weeks, removing of temporary restorations and taking of final impressions Visit 5: placement of different ceramic crown superstructures and recording different outcome values.
