Getting braces for your teeth is a popular way to correct many kinds of orthodontic problems. Metal brackets attached to each tooth are connected by wires with tension that straighten your teeth—but how does your orthodontist make sure those brackets stay on? It’s the interesting process of orthodontic bonding. Let’s take a closer look.
Types of Bonding
There are two main types of orthodontic bonding: direct and indirect. Direct bonding involves correctly attaching and positioning metal brackets right onto your teeth the first time. Indirect bonding is when the orthodontist first uses a plaster model of your teeth to position the brackets, and then transfers them to your actual teeth.
Preparing the Teeth
Braces can’t work unless your brackets stay where they are. To make sure that happens, the surface of your teeth have to be completely dry. This ensures that the bond between your tooth’s surface and the metal bracket will be strong enough to keep brackets where they are in the long-term. Cotton rolls, saliva ejectors, cheek retractors, and lip expanders are all tools that your orthodontist uses to keep teeth dry for the next stage.
Next, the orthodontist will etch your teeth using an acidic etching agent. Etching will make your tooth’s enamel rough so that the bonding agent will have a better hold, but don’t worry—the roughening of the enamel is microscopic. Now that your teeth are prepared, it’s time to attach the brackets.
There are two types of bonding systems available to attach brackets to your teeth: no mix and two-paste mix.
The no mix system consists of a liquid primer and paste. The primer is placed on the etched surface of the tooth and on the base of the bracket. The paste is then applied to the bracket base, and the bracket placed onto the tooth.
In the two-paste mix system, two bonding resin liquids are mixed and applied to etched tooth enamel, and two pastes are mixed and applied to the base of the metal bracket before placing it onto the tooth.
Once the brackets are placed on your teeth with the one or two mix bonding systems, that bond has to be hardened or cured with a curing lamp. Your orthodontist will use either a halogen or an LED curing lamp, placing it as close as possible to your metal brackets. The higher the intensity of the light, the less time it will take to harden the bonding agent. After that, wires are placed between each bracket, and you’re good to go.
