Dual Rectangular & Round Slots for Maximum Versatility
The bracket-shaped orthodontic head features an inner rectangular slot (.022” x .025”) and two outer rectangular slots (.022”), alongside two round through-holes (.027”). This versatile design ensures fastening devices like elastic threads, chains, and metal ties stay securely in place without slipping against soft tissues, maximizing anchorage stability and patient comfort.

Tapered Self-Drilling/Self-Tapping Thread
Engineered with a specialized asymmetrical profile, the infraosseous portion allows for direct insertion without pre-drilling in most cases. This minimizes surgical trauma, accelerates the placement procedure, and guarantees exceptional primary stability and maximum resistance to tensile forces.

Product Description
Revolutionize your orthodontic skeletal anchorage with the HDC Spider Screw SL (Self-Ligating), the world's only mini-screw equipped with a patented self-ligating mechanism. Designed in collaboration with leading international orthodontic experts, this advanced Class II medical device simplifies complex tooth movements by eliminating the need for traditional ligatures. Its innovative internal locking system allows clinicians to effortlessly secure round or rectangular wires with a quick 45-degree turn of the head slot. When used independently or paired with the Spider Link preformed power plates, the Spider Screw SL provides absolute, immediate-loading anchorage for distalization, intrusion, and asymmetric dental movements—all while significantly reducing treatment times and eliminating the need for patient compliance.
Engineered from premium Grade 5 Titanium for superior biocompatibility, the Spider Screw SL ensures maximum clinical reliability and patient comfort. The bracket-shaped orthodontic head is meticulously crafted with dual rectangular slots (.022” x .025” inner; .022” outer) and .027” round through-holes, preventing elastic chains or metal ties from slipping into soft tissues. Below the surface, the screw features a highly polished, conical transmucosal collar that prevents plaque accumulation and tissue irritation. Its self-drilling and self-tapping asymmetrical thread profile allows for smooth, pre-drill-free insertion in most anatomical sites, guaranteeing outstanding primary stability. Available in both K1 (Ø 1.5 mm) and K2 (Ø 1.9 mm) diameters with various lengths, the Spider Screw SL is the ultimate, versatile solution for modern orthodontic practices.
