Open Coil Spring is an essential tool in orthodontic practice aimed at creating and maintaining space for the alignment of misaligned teeth. This spring is designed to fit between brackets, effectively stretching and opening up space within the dental arch. Periodic reactivation ensures consistent force application, crucial for gradual tooth movement and optimal alignment. The length of the coil spring varies based on the distance between the anterior and posterior hooks and the amount of extraction space available. With its durable construction and reliable performance, the  open coil spring supports orthodontists in achieving precise and effective tooth positioning, enhancing overall treatment outcomes and patient comfort.
