Rehabilitating Amputated Hallux with Dental Implant–Supported Double Magnet in Y-Bar–Retained Prosthesis

Abstract

ABSTRACT Introduction Loss of hallux leads to aesthetic deficit and functional loss, with active push-off, weight-bearing ability, and pronation all being affected. Rehabilitation can be surgical or prosthetic; however, surgical alternatives can be unpredictable in terms of aesthetics and is not cost-effective. Therefore, prosthetic rehabilitation is often favored. However, loss of all 3 phalanges makes prosthetic rehabilitation challenging due to minimal scope of retention from the residual limb. Materials and Methods This technique presents a solution to this challenge, with an implant-supported, magnet-retained silicone prosthesis, having a novel abutment design, to provide dual (magnetic and frictional) retention. Conclusions The prosthetic design improved retention, facilitated easy handling by the patient, and prevented stress concentration on implant-bone interface. Clinical Relevance The prosthetic innovation improved retention during standing and walking, and increased the patient’s confidence to perform daily activities without fear of dislodgement.
