Summary

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.

Interventions

PROCEDURE

Ball & Socket Attachment

Two implants will be restored using ball-and-socket attachment systems, with the mandibular denture retained over these attachments through corresponding metal housings
