A dental implant that facilitates insertion includes a body having a coronal end (44) and an apical end (42) opposite the coronal end (44). An implant-prosthetic interface region (16) is provided adjacent the coronal end (44). A tapered region (22) is adjacent the apical end (42). A variable profile helical thread (41) extends along the tapered region (22). The thread (41) becomes broader in the apical-coronal direction and higher in the coronal-apical direction. The threads (41) include and apical side (A), a coronal side (C) and a lateral edge (T) connecting them. The variable profile thread (41) includes an expanding length of the lateral edge (T) while the distance of the lateral edge (T) from the base is reduced in the direction of the coronal end (44). The implant also has a gradual compressing tapered core (40), a self drilling apical end (42) with a spiral tap, and a coronal end (44) with and inverse tapering.
