Full Arch Implant SurgeryFull arch prosthesis
Full Arch Implant Surgery: A surgical and prosthetic treatment involving the placement of 4, 6 or 8 dental implants in the edentulous maxilla or mandible, potentially preceded by sinus augmentation if needed.
Full arch prosthesis: This intervention includes the full surgical and prosthetic treatment for edentulous patients undergoing full-arch implant-supported rehabilitation. The treatment consists of two main phases:
Immediate implant placement with provisional prosthesis: A surgical procedure is performed for the placement of 4, 6, or 8 implants per arch (maxilla or mandible), with or without sinus augmentation depending on the case. On the same day, a screw-retained acrylic provisional prosthesis is delivered, allowing immediate functional and aesthetic rehabilitation. Definitive prosthesis delivery:
After a healing period of approximately 3 to 6 months, once osseointegration and soft tissue stabilization are confirmed, a definitive screw-retained prosthesis is fabricated and delivered. Definitive prostheses may be manufactured from monolithic zirconia, veneered zirconia, or hybrid materials depending on the case. Both prosthetic phases are part of a standardized treatment protocol performed under control.
Study summary
Full-arch implant-supported fixed dental prostheses are a widely accepted treatment for edentulous patients, with high long-term implant survival rates. However, further research is needed on longer-term patient satisfaction and on the psychosocial impact of this treatment on patients' daily life and functioning. Assessing patient-reported outcomes - oral health-related quality of life (OHRQoL) and patient satisfaction - allows the impact of full-arch rehabilitation on patients to be evaluated.

Inclusion Criteria:
Adults aged 18 years or older. Patients requiring full-arch implant-supported rehabilitation of the maxilla and/or mandible.
Patients with indication for immediate full-arch implant-supported rehabilitation using 4, 6, or 8 implants per arch, according to anatomical and clinical conditions.
Patients able to understand the study procedures and complete patient-reported outcome questionnaires Patients willing to provide written informed consent.
Exclusion Criteria:
Patients with medical contraindications for implant surgery. Patients unable to provide informed consent. Patients unable to complete the study questionnaires Patients with uncontrolled systemic conditions that may contraindicate implant therapy.
Patients unable or unwilling to attend the planned follow-up visits. Patients receiving partial-arch implant rehabilitation only.
Primary outcome measure(s)
Change in Oral Health-Related Quality of Life measured by the Oral Health Impact Profile-14 Portuguese version — [Time Frame: T0 - baseline before surgery; T1 - day of surgery; T2 - 1 month after surgery and provisional prosthesis placement; T3 - prior to definitive prosthesis delivery (approximately 3 to 6 months); T4 - 1 month after definitive prosthesis placeme People's perceptions of the social impact of oral disorders on their well-being: oral health quality of life (OHIP-14).
Oral health-related quality of life will be assessed using the Portuguese validated version of the Oral Health Impact Profile-14 (OHIP-14). The OHIP-14 includes 14 items, each scored from 0 to 4, generating a total score ranging from 0 to 56. Higher scores indicate poorer oral health-related quality of life and greater negative impact of oral conditions on daily life. The primary outcome will be the change in total OHIP-14 score during full-arch implant-supported rehabilitation.
