Mandibular Implant Overdenture With Bar vs OT Equator: A Randomized Controlled Trial

A bar attachment supported by three mandibular implants (placed in the midline and canine regions) is used to retain a mandibular overdenture. The bar provides rigid splinting across the implants and allows retention using friction or clips, without additional attachment components. This serves as the control group.

A bar attachment supported by three mandibular implants is combined with two OT Equator attachments to enhance denture retention and allow slight vertical and rotational resilience. The OT Equator system includes metal housings and retentive nylon caps, intended to reduce cap wear and improve patient comfort. This is the experimental arm.
