Morphology of Polycrystalline Alumina Brackets and its Relationship to Fracture Toughness and Strength
Morphology of Polycrystalline Alumina Brackets and its Relationship to Fracture Toughness and Strength
Page Range: 197 – 203
Inherent defects seen in the morphology of polycrystalline ceramic brackets severely limit their fracture strength. Only by improving the surface characteristics can those mechanical properties which are necessary for sufficient strength and efficient orthodontic tooth movement be more fully realized.Abstract
