Full Arch Rehabilitations Through the Contemporary All-on-4 Concept

Sponsor: Malo Clinic

View on ClinicalTrials.gov

Summary

It is necessary to generate more evidence on the outcome of contemporary protocols for full-arch rehabilitations supported by implants in immediate function in areas with limited quantity and density bone. This research project aims to investigate the outcome of fixed prosthetic restorations supported by implants in immediate function for full-arch rehabilitation through the All-on-4 concept contemporary protocol, specifically: implant survival and success, prosthetic survival, marginal bone level and marginal bone level changes, soft tissue health parameters (Plaque index, Bleeding index, Pocket depth), incidence of biological and mechanical complications. A prospective cohort study design will be used in the investigation. The sample of this study is estimated to consist in 43 patients rehabilitated with full-arch fixed prosthetic rehabilitations supported by implants in immediate function (All-on-4 concept) with 144 dental implants. The cohort will be evaluated between baseline and 3 years of follow-up.
