Overview
In patients that did a full mouth implant supported rehabilitation does Cad/Cam Monolithic Zirconia compared to Cad/Cam Zirconia Suprastructure (zirconium oxide (Yttrium - partially stabilized with tetragonal polycrystalline structure) veneered with feldspathic ceramic, has less post-insertion complications after at least 1-Year follow-up ?
Detailed description
Study the behavior of implant supported rehabilitations made from full-zirconium dioxide (monolithic with buccal veneer (MZ) or full contour monolithic (FCMZ) ) and zirconia veneered with feldspathic (PVZ) in full-mouth type of rehabilitations (maxilla and mandible).
In a private clinic we will record the behavior, regarding prosthodontic and biological complications in different groups (MZ vs FCMZ vs PVZ) after at least 1 year in function.
We will make calibration of the investigators for prosthodontic and biological assessement and accepting an inter-observer agreement (Kappa) of 0.9 for each parameter.
Recording will be made without the help of magnifying utilities such as magnifying glasses or optical microscopes.
Interventions
- Device Dental Implant
Place dental implants in both jaws (maxilla and mandible) according to manufacturer specifications - Device Monolithic Zirconia (MZ)
rehabilitation with monolithic zirconia implant-prosthesis with bucal feldspathic veneer - Device Zirconia-Feldspathic (PVZ)
restore dental implants with a zirconia suprastructure and feldspathic veneers - Device Monolithic Zirconia (FCMZ)
Full contour full arch zirconia rehabilitation
Primary outcome measures
- Total Amount of Chipping [Time frame: at least 1-Year post-insertion]

- Number of prosthesis failures [Time frame: at least 1-year post insertion]
Secondary outcome measures (1)
- Biological complications [Time frame: at least 1-Year post insertion]
