Retention, Chewing Efficiency and Masticatory Performance of Partial Dentures Opposing Implant Retained Prosthesis.

Retention, Chewing Efficiency and Masticatory Performance of Maxillary Flexible Versus Computer Aided Design/Computer Aided Manufacture(CAD/CAM) Partial Dentures Opposing Fixed Implant Retained Prosthesis.

This study aims to evaluate retention ,chewing efficiency and masticatory performance of flexible versus CAD/CAM partial dentures opposing to fixed implant retained restorations.

Study Overview

• Status: Completed
• Conditions: Implant Complication; Implant Site Reaction
• Intervention / Treatment: Device: evaluation of retention of Versacryle and CAD/CAM partial dentures by force gauge; Device: chewing efficiency by electromyograph(E.M.G); Other: masticatory performance(questionnaire)

Detailed Description

in this study 22 patients will be selected following inclusion and exclusion criteria. The patients will be divided randomly into two groups.

Group I patients will receive Versacrylic removable partial denture. group II patients will receive CAD/CAM removable partial denture all patients will be given the home care instructions at night and brush cleaning of the dentures.

Measurements of retention using universal testing machine, masticatory performance using T-scan III computerized system and chewing efficiency using chewing function questionnaire
