Crimpable Hook-Long Curved Control Root Movement Avoid Gum Compression

Product Description

Orthodontic Crimpable hook-Long curved (question mark traction hook/high position free hook) is a type of orthodontic traction attachment that resembles a question mark, has a long stem, and is oriented towards the root. Its core function is to control root movement, avoid gum compression, and apply precise force. It is a special form of free hook. The precise force control achieved through the extension of the long stem root is a key consumable for controlling root movement in complex orthodontics, especially in tooth extraction and deep occlusion. There are two types of Crimpable hook-Long curved left and right, with 10 pieces per bag.

Mechanism of Action

1. Provides Traction Points: In orthodontic treatment, archwires alone often provide limited forces. As a specialized hook, the question-mark hook can be attached to the brackets of specific teeth (such as premolars), serving as an anchor point for connecting elastics or coil springs.

2. Alters Force Direction: In conjunction with traction from various positions, it applies forces in specific directions to the teeth. This allows for precise control over the tooth movement trajectory, such as retracting protruding incisors or aligning crowded canines into their correct positions.

Core functions and advantages

Root Control Mobile (Core Value)

The long handle brings the traction point closer to the center of tooth resistance (1/3 of the root), avoiding tilting of the crown and achieving overall movement/controlled root retraction, especially suitable for tooth extraction and gap closure, anterior tooth retraction, and root control of molars.

Prevent gum compression

Keep the hook head away from the gingival margin to avoid compression of the root gum by rubber bands/elastic chains, and reduce mucosal ulcers and redness; The handle can be bent to adjust the height.

High position/root traction

Provide vertical/root traction for lowering teeth, correcting deep occlusion, adjusting torque, and improving bite.

Strong support and stable traction

Long handle+clamping fixation, more stable fixation, less prone to slipping, suitable for interdental traction, cross traction, and strong support cases.
