The Latest in Orthodontic Appliances

There are many different factors involved when it comes to getting that perfect smile. We use the following orthodontic appliances to help move things along and even speed the process up a bit:

  • Palatal Expander

    Appliances such as the Palatal Expander, commonly known as a Rapid Palatal Expander, are used to widen the upper jaw. This will allow the top and bottom teeth to fit together properly. This appliance works best in patients under 15 because up until this age the bones in the jaw are still flexible.

    The Expander has a screw which is attached to the teeth by bands which wrap around and it’s activated by turning the screw with a key. As the upper jaw is widened by the expander it allows a space to develop between the front teeth.

    This space will usually close by itself within a month’s time. Once the expansion has been successful, the Expander will remain in the mouth for about four to six months to stabilize before it is removed.

  • Twin Blocks

    Twin Blocks are another appliance which incorporates the use of upper and lower bite blocks. This is used to position the lower jaw forward to correct certain conditions. This orthodontic appliance is starting to be seen more often as they are very functional.

  • Lower Lingual Holding Arch

    Another appliance which is commonly used by orthodontists is the Lower Lingual Holding Arch. This is a appliance which prevents the permanent molars from shifting forward. It’s used to allow crowded teeth to be able to spread out.

    The Lower Lingual Holding Arch stays in place until the permanent teeth begin to come in. There are then two bands which are cemented to two lower molars, and attached to those bands is a U-shaped bar.

  • Nance Holding Arch

    A Nance Holding Arch is another common orthodontic appliance. It consists of two bands around the upper back teeth and an acrylic button that covers part of your anterior palate.

    It can be used as a space maintainer in certain cases where the baby teeth have been lost too early. It’s used to prevent the first molars from coming forward while pushing the anterior teeth back.

    It also has a slight effect on the patient’s speech. While this appliance is installed it’s recommended that you stay away from any hard sticky food. These foods may break your holding arch. Make sure you’re also brushing all parts of the holding arch along with your teeth.

  • Headgear

    Headgear is another tool orthodontists use to make more space for teeth to come in. It can be attached to the upper molars using headgear bands and tubes. This helps to draw the molars backward into the mouth which will then open up space for the front teeth to also be moved back. The front teeth will be moved backward using braces and bands.

    Headgear is most commonly used for correcting anteroposterior discrepancies in Cl II malocclusions This is meant to slow or stop the upper jaw from growing and can be used to either prevent or correct and overjet.

    The headgear will attach to the upper molars using a facebow. A neck strap or a headcap is used to anchor the headgear to the back of the neck or head.

    It also has a slight effect on the patient’s speech. While this appliance is installed it’s recommended that you stay away from any hard sticky food. These foods may break your holding arch. Make sure you’re also brushing all parts of the holding arch along with your teeth.

  • Facemask

    The Facemask is an appliance commonly used in the early treatment of Class III malocclusions where the upper jaw is anteroposteriorly (front-back) deficient. It is designed to apply forward and downward traction on the upper jaw.

    A metal bar acts as a framework to maintain support to the forehead and chin. An extraoral force is applied through two elastics attached to hooks mounted on a fixed intraoral appliance (usually a palatal expander) toward an adjustable bar attached to the vertical framework.

  • Temporary Anchorage Devices

    Temporary anchorage devices are very small titanium screws (mini-screw) or titanium plates that are placed into the jawbones to serve as anchors to make some complicated tooth movements possible. TADs are removed after the completion of orthodontic treatment.

    Some tooth movements that are very hard or even impossible without this orthodontic appliance include: intruding an opposing molar to make room for a bridge, uprighting a tipped molar to make space for an implant and distalizing the upper molars to correct the overjet.

    TADs are either placed by your orthodontist or an oral surgeon or periodontist.

  • Elastics

    Elastics are commonly used with the braces. During various times of treatment the elastics/rubber bands are used to help individual tooth movement and the aligning of the jaw. They must be worn at all times, especially while eating.

Speed up Your Treatment with Appliances

Orthodontic Appliances are commonly used to assist treatment by providing additional help to move the teeth into their proper positions. They differ from retainers since they are used while your braces are on, however, they do not necessarily have to be used throughout the entire treatment.

These appliances will help speed up the process significantly and leave you with a great looking smile at the end. Contact our team at Smiles on Yonge to learn more about Orthodontic Appliances and whether they are necessary for your treatment.
