Prosthetic Complications and Patient Satisfaction of Two Different Implant Distribution

Prosthetic Complications and Patient Satisfaction of Two Different Implant Distribution for Stress Free Implant Bar Mandibular Overdenture:

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

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.
