Prosthetic Complications and Patient Satisfaction of Two Different Implant Distribution

Mansoura University30 enrolled

Overview

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.

Outcomes

Primary Outcomes

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

Time frame: one year

Secondary Outcomes

prosthetic complications

The complications include (1) complications of attachments: abutment fracture, abutment screw loosening, screw fracture, wear/distortion of retentive components, activation of retentive components, retention loss and replacement of retentive components, and separation of retentive components from the denture base, (2) technical complications of mandibular over-dentures: reline, fracture/remake, teeth wear, teeth separation/fracture, (3) technical complications of maxillary dentures: reline, fracture/remake, teeth wear, teeth separation/fracture, (4) Soft tis-sue complications of mandibular overdentures and maxillary dentures: mucositis, soreness, ulcer decubitus, hyperplasia, and flabbyridge

Time frame: one year
