What this Trial Is About
Researchers are studying changes in oral health-related quality of life (OHRQoL) during full-arch implant-supported rehabilitation for patients without teeth. The study aims to understand how patient satisfaction and the psychosocial effects of this treatment evolve over time, considering differences in the upper or lower jaw and types of prosthetic materials used. This observational study evaluates patient-reported outcomes to better understand the impact of full-arch implants on daily life and functioning. Participants will receive full-arch implant-supported prostheses using 4, 6, or 8 implants based on their individual anatomy. Treatment starts with immediate placement of screw-retained acrylic provisional prostheses, possibly including sinus lift procedures for some upper jaw cases. After 3 to 6 months of healing, a definitive screw-retained prosthesis made from monolithic zirconia, veneered zirconia, or hybrid materials is provided. Throughout the study, patients will complete validated questionnaires assessing oral health quality of life, psychosocial impact of dental aesthetics, and satisfaction with various aspects of their prosthesis. These assessments occur at multiple time points from before surgery to one month after the final prosthesis placement. Data is collected digitally and securely, allowing researchers to analyze how quality of life changes during treatment and how patient characteristics relate to outcomes.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Day of surgery
Participants undergo full-arch implant surgery with placement of 4, 6, or 8 implants depending on anatomy, with or without sinus augmentation. On the same day, a screw-retained acrylic provisional prosthesis is delivered allowing immediate functional and aesthetic rehabilitation.
1 visit (in-person)
Duration - 3 to 6 months
Participants are monitored during a healing period to allow osseointegration and soft tissue stabilization before definitive prosthesis delivery.
Visits as per clinical indication
Duration - 1 month
Participants receive a definitive screw-retained prosthesis made from monolithic zirconia, veneered zirconia, or hybrid materials after the healing period.
1 visit for prosthesis delivery and follow-up assessments
