NCT04446078

Brief Summary

It is necessary to evaluate the outcome of implant supported fixed prosthetic rehabilitations using peek material. To test this, the study design to be used will be a prospective single cohort to evaluate the long term outcome of fixed prosthetic implant supported rehabilitations. The cohort will be evaluated after 5 years of follow-up, regarding prosthetic survival, implant survival, marginal bone resorption, incidence of mechanical complications (loosening or fracture of prosthetic components), biological complications (peri-implant pathology, suppuration, fistulae), incidence of biological complications (peri-implant pathology, suppuration, excessive marginal bone resorption) in-mouth comfort, overall chewing feeling, framework integrity, veneer adhesion, veneer chipping, patient tissue reaction, denture staining, manufacture issues,
