Implant Design & Surface Mini-threads with Double-lead Threads for Faster Insertion The body of all Spectra-System implants (excluding RePlant Implant) are tapered evenly down from the top to facilitate insertion in an undersized socket (stop at intermediate drill) for expansion in soft 1.2mm bone. This increases initial stability (G. Niznick: Clinical Oral Health 2000 “Achieving Success in Soft Bone”). The SBM textured surface extends over the entire endosseous portion of the SpectraSystem implants. Mini-threads start 1mm below the crest of the bone and extend for 2-2.5mm before transitioning into doublelead threads to the apex of the implant. The Mini-threads are half the depth and half the distance between adjacent peaks compared to the double-lead threads that extend to the apex of the implant. Minithreads reduce stress in the critical crestal 1.2mm bone region while double-lead threads reduce the number of turns required to seat the implant. Vertical cutting grooves extend half way up the implant from the apex for self-tapping insertion.

Implant Direct uses the same vendor for its SBM and HA coated surface treatments as used by Paragon Implant Company from 1992-2000 when these studies were conducted.
