Modern Ortho Purity Poly Crystalline Ceramic Brackets

Ceramic brackets are developed for esthetic purposes. Other esthetic materials have also been used—for example, plastics and polycarbonate-based materials.Ceramic brackets exhibit higher hardness and stiffness; however, they showed a higher incidence of fracture due to brittleness and aging in the oral environment. 

ADVANTAGES ON USING CERAMIC BRACKETS:

• Friction: Friction between a ceramic bracket and wire is much higher than that of a metal bracket
• Aesthetics: Ceramic brackets are aesthetic 
• Slim/Thin Brackets

METAL SLOT IN CERAMIC BRACKETS:

One of the modifications of ceramic brackets are ceramic brackets designed with a metal slot:-

• For improving sliding mechanics and to withstand higher torquing forces

Ceramic orthodontic brackets are made out of either polycrystalline or monocrystalline alumina (aluminum oxide, Al2O3)

• Polycrystalline brackets tend to have a more whitish (tooth-colored) look

• Dove Tail Grooves:

  • For pure mechanical bonding

  99.99% Pure Alumina:

  • Extremely resistant to slot wear cracking and fracturing

  Translucent:

  • For pleasing aesthetics
