Current evidence for IOD and IARPD

Abstract

Implant overdenture (IOD) is a field in which evidence has been rapidly accumulating since around 2000, when McGill consensus and York consensus were announced. There are many variations of IOD, including mandibular 2-IOD, which is an established technique, 1-IOD, mini-IOD using mini-implants, and different types of attachments. The clinical applications of maxillary IOD and Implant assisted removable partial denture (IARPD) for partial defects has been also increasing. In this paper, we would like to introduce the latest evidence on IOD and IARPD from about 200 clinical studies since 2000, and summarize what we know so far according to the following items.
