OrthoForm I Tapered arch form provides the narrowest inter-cuspid width and is indicated in patients with narrow, tapered arch forms
OrthoForm II Square anatomical arch form handles varying bracket base thickness with a broad anterior segment and lingually curved distal
When used with settling and retention procedures, the OrthoForm III Ovoid arch form minimizes post-treatment relapse
3M™ OrthoForm™ Arch Form Selection provides three distinct arch forms (Tapered, Square, & Ovoid) that reconcile the variation in curvature and width for MBT™ Appliance System Treatment.
For over a century, there has been a persistent search for the ideal arch form for human dentition. Changes to arch form during treatment may result in instability and subsequent relapse, which can contradict this search for the ideal arch form. In addition, there is an awareness that a great deal of variation exists from one human arch form to another. With this in mind, 3M Unitek developed three distinct arch forrms.
OrthoForm™ I Tapered Arch Form
OrthoForm™ II Square Arch Form
OrthoForm™ III Ovoid Arch Form
All three of these arch forms complement the MBT™ Appliance System Treatment Philosophy.
