Clinical changes after two-month of single palatal force application and four months of “double cable” mechanics application. A. After two-month of single palatal force application, inter-premolar width (IPW) and the inter-molar width (IMW1, IMW2) decreased; inter-premolar width (IPW) decreased and the inter-molar width (IMW1, IMW2) increased with four months of “double cable” mechanics application. B. The inter-premolar width to the inter-second molars width ratio (IPW/IMW2) increased after two-month of single palatal force application. The inter-premolar width to the inter-second-molars width ratio (IPW/IMW2) decreased with four months of “double cable” mechanics application. C. The distances from the upper incisors to palatal plane (UIPP) and upper molars to the palatal plane (UMPP) increased after two-month of single palatal force application. The distances from the upper incisors to palatal plane (UIPP) was controlled with four months of “double cable” mechanics application.
