Summary

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

Detailed description

The aims of this randomized control trial are: 1. To describe a method to chemically etch the bases of stainless steel orthodontic brackets. 2. To observe the changes in the micro-structure of the brackets with sandblasted bases and acid-etched bases under an electron microscope. 3. 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

Conditions

• Orthodontic Appliances

Interventions

Type	Name	Description
DEVICE	Acid etched brackets	The brackets will be bonded to the teeth with composite on the same patient in a split mouth design and observed for bracket debonding for 18 months
DEVICE	Sandblasted brackets	The brackets will be bonded to the teeth with composite on the same patient in a split mouth design and observed for bracket debonding for 18 months
