ABSTRACT:
A dental implant for having a longitudinal axis for implanting in bone, has a crest module having a top end, a bottom end and a wall having an outer surface and a threaded section. The threaded section has a crestal end and an apical end, the crestal end abutting the bottom end of the crest module, a helical thread extending along a portion of the first section from a base end outwardly to a distal end. The threaded section also has a length, a major diameter being defined as the diameter of the threaded section measured at the distal end of the thread and a minor diameter being defined as the diameter of the threaded section measured at the base end of the helical thread. The major diameter is constant along the length of the threaded section, whereas a selected thread feature is chosen as a function of a selected biomedical characteristic. The selected thread feature could include the minor diameter, the thread pitch or the thread geometry. The selected biomedical characteristic is one of the location in the bone in which the implant is placed, the elastic modulus of the bone and the desired biomechanical response of the bone.
