Figure 3: The calculated arch form dimension was used to interpret the shape of arch form by using a mathematical formula (CD/MD)/(CW/MW).[17] CD: Canine depth, MD: Molar depth, CW: Canine Width, and MW: Molar Width. When the Wc/Wm ratio increases of the Dc/Dm ratio decreases, the arch becomes squarer. On the contrary, when Wc/Wm ratio decreases or Dc/Dm ratio increases, the arch gets a more tapered form. Therefore, the formula is used to describe the arch form
