Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Among attachment systems, ball-type anchors have long been favored for their simplicity and cost-effectiveness. However, the Equator attachment has emerged as a refined alternative, providing superior retention and stability for implant overdentures.
Functional performance can be evaluated through electromyography, which records masticatory muscle activity, and the T-Scan system, which analyzes occlusal force distribution and timing during dynamic occlusion. Additionally, bite force measurement serves as a key indicator of prosthetic efficiency and neuromuscular function, with implant-retained overdentures showing higher values than conventional dentures. This study aimed to compare bone level changes, occlusal force distribution in patients wearing mandibular implant overdentures retained by Equator and ball-and-socket attachments.
