Why use Single Brackets rather than Twins?
In orthodontics, the amount of force placed upon the teeth will affect the movement of these teeth. Teeth will move in three dimensions 1) Labio-lingually, 2) Inciso-gingivally, and 3) Mesio-distally. The challenge is to move the teeth into their desired positions in a direct path with the smallest amount of force possible. The first decision is to determine where the teeth should be at the end of treatment your treatment goals. Then proper mechanics should be employed to gently move those teeth into these predetermined positions. In a fixed appliance, teeth can be moved by first placing brackets on the teeth, then inserting an archwire into these bracket slots. The archwire will deliver the forces to move the teeth. So, the amount of movement and direction of movement of the teeth is determined by the bracket design and the archwires used. Another factor that may have a limited effect upon the tooth movement could be the intraoral muscular forces. It is well known that orthodontic for
