Abstract

Overdenture using dental implants could improve the problems of conventional complete denture function which are pain during mastication, insufficient retention and stability. Locator attachment used widely for implant-retained overdenture has advantages that it needs the smallest vertical space and also its nylon male cap allows personalized retention for each case. However its retention force decreases rapidly with function rather than the bar and ball attachment. So, implant fixture should be positioned as parallel as possible.
