SPIDER SCREW
K1 -K2 -Z
Many features in a few square millimeters make the orthodontic head of K1 – K2 miniscrews a unique anchoring system (protected by international patent) with multiple advantages.
The only system with two heights of the transmucosal collar.
The two External Rectangular Slots (Fig. 1) allow the direct housing of orthodontic wires. The wide Internal Rectangular Slot (Fig. 2) ensures that connecting devices (elastic wires, chains, metal ligatures, etc.) do not detach from the miniscrews and, at the same time, do not slide against soft tissues, causing loss of anchorage.
The two Pass-through Round Slots (Fig. 2) have a funnel-shaped initial part to facilitate the insertion of wires, metal ligatures, hooks, etc.
The size of the Spider Screw head has been designed to ensure maximum patient comfort.
