Fig. 1From: Effects of implant thread design on primary stability—a comparison between single- and double-threaded implants in an artificial bone modelImplants. Implant code 12S is similar to a commercially available standard single-threaded implant with equal thread pitch and a 1.2-mm lead. The thread length of implant code 06D is doubled by adding the second thread (light blue). The thread length of implant code 06S is doubled by a 50% reduction in pitch and lead angles. Characteristics of each implant are summarized in Table 1Back to article page
