implant overdenture
A removable complete or partial denture that derives support and retention from two or more dental implants, typically via ball attachments, locator attachments, or a bar-and-clip system.
Full Definition
An implant overdenture (also termed an implant-retained overdenture or implant-supported overdenture, with important distinctions) is a removable prosthesis that engages implant attachments to improve stability and retention compared to a conventional denture. The prosthesis overlies the implants and, in some designs, the residual ridge. Editors should be alert to the clinical distinction: an 'implant-retained overdenture' derives retention from implants but support from the ridge, while an 'implant-supported overdenture' derives both support and retention from implants. These distinctions must be preserved accurately in clinical manuscripts. The word 'overdenture' is one closed compound (no hyphen, no space).
Usage
Usage note: 'Overdenture' is a closed compound — one word, no hyphen. Preserve the clinical distinction between 'implant-retained' (retention only from implants) and 'implant-supported' (both support and retention from implants), as the two terms are not interchangeable.
In Context
- "A mandibular implant overdenture retained by two ball attachments was selected as a cost-effective solution for the edentulous patient." — Prosthodontic treatment planning note
- "The manuscript used 'implant-supported' and 'implant-retained' interchangeably throughout; the editor flagged this as a clinically significant distinction requiring author clarification." — Peer review editorial note
