The body of all Spectra-System implants are tapered to facilitate insertion in an undersized socket (stop at intermediate drill) for expansion in soft 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 Spectra-System implants.

The SBM textured surface extends over the entire endosseous portion of the Spectra-System implants. Mini-threads start 0.5-1mm below the crest of the bone and extend for 2-2.5mm before transitioning into double-lead threads to the apex of the implant.
The minithreads 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.
Mini-threads reduce stress in the critical crestal bone region while double-lead threads reduce the number of turns required to seat the implant. Vertical cutting grooves extend halfway up the implant from the apex for self-tapping insertion.
SBM and HA Coated Surface Options
SBM surface is created by using a Soluble Blast Media of Hydroxylapatite (HA) crystals to create a medium-rough texture. We use the same vendor for our SBM and HA coated surface treatments as was used by Paragon Implant Company from 1992-2000 when these studies were conducted.
