Orthodontic spacer removal. [2] Spacers are usually used to put spaces in between teeth before braces are established. It can be agitating or painful, but patients are often warned not to pick at them or they will fall out. They are usually rubber, but sometimes they can be metal. They can be used when a patient's teeth are too close together.
Palatal expander in mixed dentition. Rapid palatal expansion (RPE) or Rapid Maxillary Expansion (RME) is an expansion technique where expansion of 0.5 mm to 1 mm is achieved each day until the posterior crossbite is relieved.
A systematic review concluded that for decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth (Hall technique) or only partially removing decay (also referred to as "selective removal" [5]) before placing a filling may be better than the conventional treatment of removing all decay before filling. [6]
For example, with clear braces, impressions of a patient's teeth are evaluated to create a series of trays, which fit to the patient's mouth almost like a protective mouthpiece. With some forms of braces, the brackets are placed in a special form that is customized to the patient's mouth, drastically reducing the application time.
The American Journal of Orthodontics was created for this purpose in 1915; before it, there were no scientific objectives to follow, nor any precise classification system and brackets that lacked features. [16] Until the mid-1970s, braces were made by wrapping metal around each tooth. [9]
Different shaped forceps are available depending on the type of tooth requiring removal, what side of the mouth (left or right) it is on and if it is an upper or lower tooth. The beaks of the forceps must grip onto the root of the tooth securely before pressure is applied along the long axis of the tooth towards the root.
In this procedure, a dentist or orthodontist attaches braces to certain teeth (typically the canines and premolars) and inserts wiring, but not elastics, between the upper and lower teeth in a figure-8 pattern. The wiring is removed periodically to allow the jaw joints to move freely, especially in the vertical direction.
Unlike braces, headgear is worn partially outside of the mouth. An orthodontist may recommend headgear for a patient if their bite is more severely out of alignment. The device typically transfers the force to the teeth via a facebow or J hooks to the patient's dental braces or a palatal expander that aids in correcting more severe bite ...
