An implant bar attachment system and method includes an elongate bar for extending between at least two implant sites and at least two fastener devices at opposite ends of the bar for securing the bar to the respective implants. The bar has socket formations for snap engagement with the heads of respective male members secured to an overlying denture. At least some of the socket formations are provided in the heads of female fastener devices which extend through bores in the bar at respective implant sites for connection to an implant or implant abutment, so that the denture attachment point is coaxial with the implant.
