Abstract

Retrospective data of 32 patients supplied with implant-supported and Locator attached overdentures were screened for prosthetic complications and maintenance requirements, which were recorded and statistically analyzed. Mean observation time was 4.78 (± 1.72) years. Loss of retention was the most frequently observed event (n=22). Damage and exchange of the insert holders (n=4) and loosening of locator attachments (n=2) and fracture of the insert holder (n=2) were uncommon events; no loss of locator attachments was observed. Loss of retention in Locator-attached overdentures is frequent; correlating patient-specific parameters with prosthetic complications is necessary to define recommendations for the use of Locator attachments.
