Total Amount of Chipping [ Time Frame: at 1-Year post-insertion ]
measure the total number of ceramic fractures (chipping) visible at naked eye in both groups (monolithic and feldspathic) that happen from insertion (baseline) to 1 year post-insertion.
Same as current

  • Number of Small Complications [ Time Frame: at 1-Year post Insertion ]

    Measure the total amount of adverse events other than chipping, that made the patient come to the dental office, that happen from insertion (baseline) to 1 year post-insertion.

    It is determined that if the complication was solved in the dental chair is considered a Small complication

  • Number of Big Complications [ Time Frame: at 1-Year post Insertion ]

    Measure the total amount of adverse events other than chipping, that made the patient come to the dental office, that happen from insertion (baseline) to 1 year post-insertion.

    It is determined that if the complication was solved in the dental laboratory is considered a Small complication

Monolithic Zirconia Full-Mouth Implant Supported Rehabilitation Behavior
Cad/Cam Monolithic Zirconia Behavior in Full-Mouth Implant Rehabilitation - Case-control Study
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 1-Year follow-up ?

Retrospectively study the behavior of implant supported rehabilitations made from full-zirconium dioxide (monolithic) and zirconia veneered with feldspathic in full-mouth type of rehabilitations (maxilla and mandible).

In a private clinic we will record the behavior, regarding chipping and complications in both groups (monolithic vs feldspathic ceramic) after 1 year in function.

We will make calibration of the investigators for chipping detection, characterization of big and small problem and accept 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.
