Implant Direct Spectra-System®

Mini-threads with Double-lead Threads for Faster Insertion

The body of all Spectra-System implants are tapered evenly down from the top 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 theentire endosseous portion of the Spectra-System implants. Mini-threads start 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 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. Mini-threads reduce stress in the critical crestal bone region while double-lead threadsre- duce the number of turns required to seat the implant. Vertical cutting grooves extend halfway up the implant from the apex for self-tapping insertion.
