NCT07400380

Brief 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

Outcome Measures

Primary Outcomes (1)

  • patient satisfaction

    A visual analog scale (VAS) and oral health-related quality of life (OHRQoL) were used for evaluating patient satisfaction. Participants in the VAS were instructed to draw a vertical line anywhere along a horizontal line that was used as a scale, with 0 mm representing the worst and 100 mm representing the best. at the point that most accurately reflected their perceptions. General satisfaction, denture stability and retention, occlusion, comfort, ease of cleaning, ease of speaking, ease of chewing, bolus quality, and aesthetics

Secondary Outcomes (1)

  • prosthetic complications

Study Arms (2)

quadrilateral group

OTHER

4-implants were distributed in quadrilateral distribution, 2-Implant in canine region and 2-Implant were inserted 26mm posterior to canine implant.

Procedure: four implants inserted in the mandible and distributed in quadrilateral manner and SFI-Bar had been inserted

curved group

OTHER

Receive four implants distributed in interforaminal distance, 2-Implant were inserted in canine region and 2- implant 8mm posterior to canine implants.

Procedure: four implants inserted in the mandible and distributed in quadrilateral manner and SFI-Bar had been inserted

Interventions

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

Also known as: four implants inserted in the mandible and distributed in curved manner and SFI-Bar had been inserted
