A flatbed dental implant that includes an open-topped cylindrical body having an ovoid elongate planar portion centrally disposed thereabouts, said planar portion disposed perpendicularly relative the cylindrical body proximal to the open end of said body, and a frustoconical member disposed basally upon the cylindrical body, said frustoconical member having a lip disposed circumferentially about the body, which lip tapers to a cylindrical ring tip enclosing the cylindrical body at a bottom end, wherein the planar portion is osteally engaged when mounted within a shallow subcortical bed incised beneath a mucoperiosteal flap of a jawbone, whereby the flatbed dental implant is securely implanted to support an extant denture therein without risking injury to the inferior aveolar nerve, maxillary sinus, or other endosteal tissue and proximal anatomy as may otherwise occur when incising to a greater depth.
