  2. Anchorage (orthodontics) - Wikipedia

    en.wikipedia.org/wiki/Anchorage_(Orthodontics)

    This type of anchorage involves using elastics from one jaw to the other, in the form of either Class 2 elastics (moving upper teeth back) where lower molar teeth serve as anchors, or Class 3 elastics (moving lower teeth back) where upper molars serve as anchors. Intramaxillary anchorage is also used in the form of E-chain, when elastics are ...

  3. Dental alveolus - Wikipedia

    en.wikipedia.org/wiki/Dental_alveolus

    Dental alveoli (singular alveolus) are sockets in the jaws in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds ...

  4. Dental implant - Wikipedia

    en.wikipedia.org/wiki/Dental_implant

    Dental implant, 3D illustration. A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor.

  5. Dental anatomy - Wikipedia

    Further, the name depends upon which arch the tooth is found in. The term, "maxillary", is given to teeth in the upper jaw and "mandibular" to those in the lower jaw. There are four classes of teeth: incisors, canines, premolars, and molars. Premolars are found only in permanent teeth; there are no premolars in deciduous teeth.

  6. Cementum - Wikipedia

    en.wikipedia.org/wiki/Cementum

    Some experts also agree on a third type of cementum, afibrillar cementum, which sometimes extends onto the enamel of the tooth. The excessive buildup of cementum on the roots of a tooth is a pathological condition known as hypercementosis. Cementum thickness can increase on the root end to compensate for attritional wear of the occlusal/incisal ...

  7. Alveolar process - Wikipedia

    en.wikipedia.org/wiki/Alveolar_process

    After extraction of a tooth, the clot in the alveolus fills in with immature bone, which later is remodeled into mature secondary bone. Disturbance of the blood clot can cause alveolar osteitis, commonly referred to as "dry socket". With the partial or total loss of teeth, the alveolar process undergoes resorption.

  8. Zygoma implant - Wikipedia

    en.wikipedia.org/wiki/Zygoma_Implant

    Zygoma implants (or zygomatic implants) are different from conventional dental implants in that they anchor in to the zygomatic bone (cheek bone) rather than the maxilla (upper jaw). They may be used when maxillary bone quality or quantity is inadequate for the placement of regular dental implants. [1]

  9. Dental arch - Wikipedia

    en.wikipedia.org/wiki/Dental_arch

    The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition.In humans and many other species, the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both ...
