A dental implant device for insertion into bone includes an implant anchor having an interlocking thread helically defined around a longitudinal axis, the thread being adapted to couple to a female threaded portion in a bone. The interlocking thread has a first superior contact surface having a first angle relative to the longitudinal axis, a second superior contact surface extending radially outward from the first contact surface and having a second angle relative to the axis, and an inferior flank surface having a third angle relative to the axis. The first angle is larger than the second angle such that the first contact surface and the second contact surface form an approximate "V" or chevron shape in a cross-sectional view. The first angle is larger than the third angle.
