Aim: This in vitro study was done to evaluate the physical, chemical and biological properties of 4 brands of metal orthodontics brackets.
Objectives: To analyse the physical, chemical, composition, the corrosion resistances, nickel ion release and cytotoxicity of the orthodontics brackets.
Materials and Methods: 4 bracket were tested for dimensional accuracy of orthodontics brackets namely group-1: Gemini (3M Uniteck), group-2: Ecoplus (Chirpans orthodontics), group-3: Monalisa (JJ orthodontics), group-4: Sapphire (Modern orthodontics). Manufacturing errors in angulation and torque, cytotoxicity, composition, elution and corrosion.
Results: The tested rackets showed no signi icant difference in manufacturing errors in angulation, but sapphire brackets showed a signi icant differ.. Read More»
