Monolithic Zirconia Full-Mouth Implant Supported Rehabilitation Behavior

Condition(s) studied

Investigational drug(s) / intervention(s)

Dental Implant: Place dental implants in both jaws (maxilla and mandible) according to manufacturer specifications

Monolithic Zirconia (MZ): rehabilitation with monolithic zirconia implant-prosthesis with bucal feldspathic veneer

Zirconia-Feldspathic (PVZ): restore dental implants with a zirconia suprastructure and feldspathic veneers

Monolithic Zirconia (FCMZ): Full contour full arch zirconia rehabilitation

Study summary

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 ?

Eligibility

Primary outcome measure(s)

• Total Amount of Chipping — at least 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 last follow-up visit Primary outcomes are defined as survival and success rates of the final prosthesis. For evaluation of these outcomes, an analysis variable will be used (Mendez Caramês et al., 2016): if no alterations are present, the prosthesis will be recorded as "Alpha"
• Number of Small Complications — at least 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 last follow up visit It is determined that if the complication was solved in the dental chair is considered a Small complication/minor chipping - not requiring any intervention besides polishing or recontouring without the need for prosthesis retrieval-"Bravo" classification will be attributed
• Number of Big Complications — at least 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 last follow up. It is determined that if the complication was solved in the dental laboratory is considered a big complication/major chipping - a "Charlie" classification will indicate the occurrence of major chipping, need for prosthesis retrieval and laboratory intervention;
• Number of prosthesis failures — at least 1-year post insertion
  a "Delta" classification will be attributed when fracture of the framework is present, defining a non-surviving prosthesis
