The following are the most commonly used terms in orthodontics.
Anterior Teeth: The upper and lower six front teeth on each arch.
Appliance: Any orthodontic device which moves or retains teeth. Appliances may also alter the positioning of the jaw.
Arch: The entire upper or lower jaw.
Archwire: The metal wire that connects orthodontic brackets. This wire guides the teeth into their new alignment.
Bands: Metal bands (rings) that are generally cemented around the back teeth.
Brackets: The tiny metal, ceramic or clear brackets that are affixed to each individual tooth on the arch.
Brushing: This is a crucial part of home dental care. Orthodontists recommend those wearing braces to brush after every meal and snack to eliminate bacteria and plaque.
Chain: Elastics connected together and placed around the brackets to stabilize the archwire and gently close spaces.
Closed Bite: The upper front teeth completely overlap the bottom teeth causing a deep overbite.
Congenitally Missing Teeth: Some permanent teeth fail to develop and erupt due to genetic factors.
Crossbite: A malocclusion in which the upper back teeth bite inside or outside the lower back teeth, or the lower front teeth bite in front of the upper front teeth.
Diagnostic Records: Records used to assess, plan and implement treatments. These records usually include medical and dental history, panoramic radiographs, bite molds and intraoral/extraoral photographs.
Elastics: Some braces may require that elastic rubber bands be attached to exert additional pressure to an individual tooth or a group of teeth.
Eruption: The way in which teeth surface through the gums inside the mouth.
Fixed Orthodontic Appliances: Orthodontic appliances which are affixed to the teeth by the orthodontist and cannot be removed by the patient.
Flossing: An essential part of home care that removes debris and plaque from above and below the gumline.
Functional Appliances: Orthodontic appliances that use the muscle movement created by swallowing, eating and speaking to gently move and align the teeth and jaws.
Headgear: A removable appliance comprised of a brace and external archwire. This device modifies growth and promotes tooth movement.
Impressions: Teeth impressions are taken to allow the orthodontist to see exactly how a patient’s teeth fit together.
Malocclusion: Literally means “bad bite” in Latin, and refers to teeth that do not fit together correctly.
Mouthguard: A removable plastic or rubber device that protects teeth and braces from sporting injuries.
Open Bite: Upper and lower teeth fail to make contact with each other. This malocclusion is generally classified as anterior or posterior.
Palatal Expander: A removable or fixed device designed to expand the palate in order create room on either the upper or lower arch.
Posterior Teeth: Back teeth.
Removable Appliance: An orthodontic brace or device that can be removed at will by the patient. It must be worn for the designated amount of time each day to be effective.
Separators: A wire loop or elastic ring placed between the teeth to create room for the subsequent placement of bands or orthodontic appliance.
Space Maintainer: A fixed appliance used to hold space for permanent (adult) tooth. This is usually used when a baby tooth has been lost earlier than anticipated.
Wax: Orthodontic relief wax is a home care remedy used to alleviate irritations caused by braces.
