About

To describe a method of acid etching the base of a bracket, and to compare the bond failures between micro-abrasive blasted (sandblasted) brackets and acid etched brackets over an eighteen month period

Full description

The aims of this randomized control trial are: To describe a method to chemically etch the bases of stainless steel orthodontic brackets. To observe the changes in the micro-structure of the brackets with sandblasted bases and acid-etched bases under an electron microscope. To compare the failure of orthodontic brackets with a chemical etched base versus a sandblasted base bonded with composite using the conventional acid etch technique, over a follow-up of 18 months
