Summary

Purpose: This clinical study aimed to evaluate patient satisfaction and prosthetic complications of different distributions of four implants supported mandibular overdentures using Stress free implant bar (SFI-Bar attachments). Evaluation was done for patient satisfaction and prosthetic complications

Detailed description

Purpose: This clinical study aimed to evaluate patient satisfaction and prosthetic complications of different distributions of four implants supported mandibular overdentures using Stress free implant bar (SFI-Bar attachments). Materials and Methods: thirty completely edentulous patients with insufficient retention and stability of their conventional mandibular denture were eligible for this study. All patients received new maxillary and mandibular dentures. The patients were randomly divided into three groups. (G1): four implants were distributed in interforaminal distance, 2-Implant were inserted in canine region and 2- implant 8mm posterior to canine implants. (G2): 4-implants were distributed in quadrilateral distribution, 2-Implant in canine region and 2-Implant were inserted 26mm posterior to canine implant. Patient satisfaction was evaluated by visual analogue scale and prosthetic complications were evaluated on the patient level and implant patients.

Conditions

• Patient Satisfaction
• Prosthetic Complication

Interventions

Type	Name	Description
PROCEDURE	four implants inserted in the mandible and distributed in quadrilateral manner and SFI-Bar had been inserted	Implant positions were planned at canines for both groups. (Intraforaminal): posterior implants are 8 mm posterior to the canine implants \[minimum allowed inter-implant distance for SFIbars (Quadrilateral): posterior implants are 26 mm posterior to the canine implants \[Maximum allowed inter-implant distance for SFI-bars
