Comparative Evaluation Of Oral Stereognosis And Masticatory Efficiency In Patients Rehabilitated With Conventional Complete Denture And Implant Supported Overdenture

Abstract

This study explores the role of stereognosis—the tactile ability to identify shapes and objects—in oral function, particularly among individuals without teeth. Alongside this, it examines masticatory efficiency, a crucial factor impacting nutrition and overall quality of life in edentulous patients. The aim was to compare these two parameters in patients rehabilitated with either conventional complete dentures or implant-supported overdentures. Twenty completely edentulous patients were selected and divided equally into two groups. Group 1 received conventional dentures, while Group 2 was provided with implant-supported overdentures. Stereognostic ability was assessed using six uniquely shaped acrylic test forms, and masticatory efficiency was evaluated by measuring the weight reduction of chewing gum after mastication. Assessments were performed at three stages: before insertion, post-insertion, and after six months. Results showed a significant improvement in both stereognostic ability and chewing efficiency in the implant-supported overdenture group compared to the conventional denture group. Patients with implant-supported prostheses demonstrated better object recognition and enhanced chewing function, likely due to improved neuromuscular coordination and denture stability. These findings highlight the functional benefits of implant-supported overdentures in oral rehabilitation and support their wider use for improving quality of life in edentulous patients.
