Summary

This study aims to evaluate and compare patient satisfaction and prosthetic complications between two types of prostheses: milled bar and screw-retained prostheses, used for supporting maxillary subperiosteal implants. Patients requiring maxillary rehabilitation using subperiosteal implants will be randomly assigned to receive either a milled bar-retained prosthesis or a screw-retained prosthesis. Patient satisfaction and any prosthetic complications will be clinical assessed and followed up over a one-year period to determine which prosthetic design offers better clinical outcomes and patient experience.

Conditions

  • Jaw Edentulous

Interventions

DEVICE

Maxillary subperiosteal implant with milled bar-retained prosthesis

Surgical placement of a custom-milled, patient-specific CAD/CAM maxillary subperiosteal implant. Following the healing and provisional phase, a definitive milled bar-retained overdenture prosthesis will be fabricated and attached to support full-arch rehabilitation.

DEVICE

Maxillary subperiosteal implant with screw-retained prosthesis

Surgical placement of a custom-milled, patient-specific CAD/CAM maxillary subperiosteal implant. Following the healing and provisional phase, a definitive screw-retained prosthesis will be fabricated and fixed to support full-arch rehabilitation.
