    Angle classification: Class II Division 1 Angle classification: Class II Division 2 Angle classification: Class III. Angle's Classification is devised in 1899 by father of Orthodontic, Dr Edward Angle to describe the classes of malocclusion, widely accepted and widely used since it was published. Angle's Classification is based on the ...

  3. Malocclusion - Wikipedia

    en.wikipedia.org/wiki/Malocclusion

    In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; [1] Edward Angle (1855–1930), the "father of modern orthodontics", [2] [3] [need quotation to verify] popularised it.

    Fixed appliances are able to produce very accurate movement in the teeth [1] [2] Both fixed and removable functional appliances can be used to correct a malocclusion in three planes: Anterior-Posterior, Vertical and Transverse. In the Anterior-Posterior dimension, appliances such as Class II and Class III are used.

  5. Edward Angle - Wikipedia

    The Angle classification divides occlusion and malocclusion into four distinct classes: normal occlusion, Class I, II, and III. Although both normal occlusion and Class I have the same molar alignment relationship, there is a distinction in how their teeth are organized in relation to the line of occlusion.

  6. Orthodontics - Wikipedia

    en.wikipedia.org/wiki/Orthodontics

    The concept of ideal occlusion, as postulated by Angle and incorporated into a classification system, enabled a shift towards treating malocclusion, which is any deviation from normal occlusion. [7] Having a full set of teeth on both arches was highly sought after in orthodontic treatment due to the need for exact relationships between them.

  7. Overjet - Wikipedia

    en.wikipedia.org/wiki/Overjet

    Class II Division I is an incisal classification of malocclusion where the incisal edge of the mandibular incisors lie posterior to the cingulum plateau of the maxillary incisors with normal or proclined maxillary incisors (British Standards Index, 1983). There is always an associated increase in overjet.

  8. Open bite malocclusion - Wikipedia

    en.wikipedia.org/wiki/Open_bite_malocclusion

    Open bite is a type of orthodontic malocclusion which has been estimated to occur in 0.6% of the people in the United States. This type of malocclusion has no vertical overlap or contact between the anterior incisors. [1] The term "open bite" was coined by Carevelli in 1842 as a distinct classification of malocclusion.

  9. Occlusion (dentistry) - Wikipedia

    en.wikipedia.org/wiki/Occlusion_(dentistry)

    Class II and III molar and incisor relationships are thought to be forms of malocclusion, however not all of these are severe enough to require orthodontic treatment. The Index of Orthodontic Treatment Need is a system that attempts to rank malocclusions in terms of significance of various occlusal traits and perceived aesthetic impairment. [ 11 ]
