Introduction
The document provides technical specifications and applications for the Al System - 3S screw, an orthodontic mini implant developed by World Bio Tech Co., Ltd. It highlights the innovative design and functionality of the implant, aimed at improving orthodontic procedures.

Specifications
The mini implants are available in various diameters (1.4mm, 1.6mm, 1.8mm) and lengths (6mm, 8mm, 10mm), each with specific codes for identification. The implants feature a hexagon head and an optimized thread system for self-tapping and self-drilling, ensuring easy insertion and stable fixation.

Design Features
The implant includes a wire slot and groove for applications up to 019025 wire, allowing the use of o-rings or ligature wires. The self-drilling tip and lateral cutting edge reduce stress concentration during insertion, minimizing the risk of implant failure.

Clinical Applications
The FIXCREW design supports various orthodontic procedures, including unilateral molar intrusion, molar distalization, intrusion and retraction of maxillary incisors, premolar lingual traction, skeletal anchorage, and narrowing of maxillary width. It is particularly effective for treatments involving canted occlusal planes and open bite correction.

Instruments
The document lists essential instruments for the application of the mini implant, including the Ortho Box MD12-M007, Drill MD12-M006, and various hand-piece drivers and handles.

Conclusion
The Al System - 3S screw represents a significant advancement in orthodontic mini implants, offering a slim yet strong design that facilitates smooth insertion and stable fixation, enhancing the efficiency and success of orthodontic treatments.
