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.

Conditions

  • Edentulous Mouth
  • Quality of Life
  • Tooth Loss
  • Oral Health Quality of Life (OHQoL) Was Assessed

Interventions

PROCEDURE

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.

DEVICE

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.
