Rehabilitation of Failing Dentition with Implant-Assisted Overdentures: A Case Report.

Abstract

This case report describes the prosthodontic rehabilitation of a 53-year-old man with failing dentition using a maxillary implant-assisted overdenture (IOD). Following full dental clearance and immediate complete denture provision, a total of six implants were placed in the maxilla with the aid of digital planning using a dual-scan CBCT technique and a 3D-printed surgical guide. The maxillary IOD incorporated an open-palate horseshoe design with metal reinforcement and Novaloc stud attachments, providing improved retention and reduced palatal coverage. At the 2-year follow-up, all implants were functional with improved patientreported outcomes, supporting maxillary IODs as an effective rehabilitation strategy aligned with the current consensus guidelines.
