Purpose: The aim of the study was to assess the influence of interimplant divergence on retention of two Locator attachments before and after in vitro simulation of 3 to 5 years of use.
Materials And Methods: A hydraulic universal testing machine was used to measure the retention of two blue Locator attachments during 5500 seating and unseating cycles. Ten pairs of Locators were tested with interimplant divergences of 0°, 10°, and 20°.
