The small elastic band used to affix the archwire to the bracket is called a ligature. Usually changed at each adjustment, these come in many varied colours, including transparent. A series of ligatures connected to each other and used to pull teeth together with more strength is called a power chain. Ligatures can also be made of wire.
Mesiodens: Mesiodens is an extra tooth that grows behind the front teeth. A mesiodens may push the front teeth apart to make room for itself thus creating a gap between the front teeth. [3] 4. Skeletal discrepancy: Dental skeletal discrepancy can be a cause behind gap teeth. If the upper jaw grows more than the lower jaw, teeth on the upper jaw ...
It is a general rule to expand the maxilla to a point where the lingual cusp of maxillary molar teeth touch the buccal cusp of mandibular molar teeth. Studies done decades ago by Krebs [ 14 ] (1964), Stockfisch [ 15 ] (1969) and Linder Aronson [ 16 ] (1979) showed that about one-third to one-half of the expansion was lost before the expansion ...
Teeth to be braced will have an adhesive applied to help the cement bond to the surface of the tooth. In most cases, the teeth will be banded and then brackets will be added. A bracket will be applied with dental cement, and then cured with light until hardened. This process usually takes a few seconds per tooth.
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.

Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments (dental drills) to prepare the tooth and can be performed in settings with no access to dental equipment.
