Summary

This study aims to compare two different prosthetic systems used in mandibular full-arch implant-supported fixed prostheses (All-on-4). The study evaluates patient satisfaction and prosthetic complications associated with the OT-Bridge system versus multiunit abutments.

A total of 20 patients will be included and divided into two equal groups. All patients will receive implant-supported screw-retained fixed prostheses.

Clinical and prosthetic outcomes will be assessed at baseline (T0), 6 months (T6), and 12 months (T12), including evaluation of patient satisfaction and any prosthetic complications.

The findings of this study may help improve the selection of prosthetic systems to enhance clinical outcomes and patient quality of life.

Conditions

  • Complete Edentulism
  • All-on-4
  • Implant Supported Prosthesis
  • Multiunnit Abutments
  • OT- Bridge

Interventions

DEVICE

OT-Bridge

OT-Bridge system is a prosthetic attachment system used for implant-supported fixed full-arch prostheses. It is designed to connect implants and provide a screw-retained restoration for mandibular All-on-4 cases, allowing improved prosthetic stability and passive fit.

DEVICE

Multiunit

Multiunit abutments are prosthetic components used in implant-supported full-arch fixed prostheses. They are placed on dental implants to correct angulation and provide a stable platform for screw-retained mandibular All-on-4 restorations.
