Bracket evolution included modifications of the base design to provide higher bond strengths with adhesives, while concurrent efforts focused on decreasing the base surface areas, which at that time covered almost the entire labial mesiodistal tooth surface. Apart from these variations in designs, brackets also differ in the material. Brackets are manufactured from Stainless steel, Gold, Titanium, Cobalt-chromium, Polycarbonate and Fibre glass, Ceramic, Magnetic and metal reinforced plastic brackets. These brackets vary in certain factors such as bond strength, friction and fracture...
