All on Four Versus All on Three Implant Treatment Concepts

Not Applicable

Completed

• Conditions: Prosthesis Durability
• Interventions: Device: implant supported fixed full arch prosthesis

• Registration Number: NCT05912127
• Lead Sponsor: Mansoura University

Brief Summary

the evaluation of patient satisfaction of All on-4 versus All on-3 implant treatment concepts rehabilitation of atrophied mandibular ridge.

Detailed Description

Patients will be classified into 2 groups according to the implant treatment concept they received:

* Group 1 (control group); included patients who received All on 4 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 2 vertical implants in the lateral incisor/canine areas.

* Group 2 (test group); included patients who received All on 3 implant-supported fixed restoration. The patients received 2 inclined implants anterior to the mental foramina and 1 vertical implant in the midline of the mandible.
