Sponsor's own description
Alveolar ridge resorption is an unavoidable consequence in complete denture wearers due to limited retention and stability. Implant-retained overdentures enhance retention, stability, and masticatory performance while reducing ridge resorption and improving patients' quality of life. 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.
