Clinical Trial Summary

The goal of this observational study is to evaluate the outcome of a Poly-ether-ether-ketone - used in partial implant-supported rehabilitations after one year of follow-up. The main question it aims to answer is: - What is the survival outcome of partial implant-supported prosthesis using Poly-ether-ether-ketone? The participants already rehabilitated with dental implants will receive a definitive 3 unit prosthesis incorporating Poly-ether-ehter-ketone.


Clinical Trial Description

Following the previous study on the full-arch rehabilitation of edentulous jaws using hybrid prostheses with polyetheretherketone (PEEK) infrastructure and acrylic resin teeth supported by implants in immediate function inserted through the All-on-4 concept it is necessary to further extend the evaluation to the partial rehabilitation using 3 Unit fixed prostheses supported by dental implants. To test this, the study design to be used will be a single-centre, prospective, observational cohort study to evaluate the short term outcome of fixed prosthetic implant-supported rehabilitations. The sample of this study consists in 10 patients consecutively treated. The cohort will be evaluated at 4 to 8 weeks, 6 months and 12 months after dental loading and annually thereafter as long as the patient is willing, regarding: prosthetic survival including repair and relining, implant survival, marginal bone resorption, incidence of mechanical complications [loosening or fracture of prosthetic components), biological complications (peri-implant infection, suppuration, abscess, fistulae), patient tissue reaction, aesthetic examination including denture staining, colour stability and anatomic form; patients' in-mouth comfort and quality of life using the Oral Health Impact Profile OHIP-14 questionnaire; and assessment of prosthetic preparation (technician satisfaction), laboratory preparation time, clinical operative time and costs. ;
