This asymmetrical thread incorporates expanded wings for better primary stability in the bone. The screw’s purposefully sharp tip ensures that the thread penetrates the receiving site. In addition, the self-tapping property combined with the self-drilling thread tends to result in better removal of chips, thus improving screw penetrability.
