Class I with severe crowding and labially erupted canines Class II molar relationship Edward Angle , who is considered the father of modern orthodontics, was the first to classify malocclusion. He based his classifications on the relative position of the maxillary first molar . [ 33 ]
Class I: The molar relationship of the occlusion is normal or as described for the maxillary first molar, with malocclusion confined to anterior teeth [4] Class II : The retrusion of the lower jaw with distal occlusion of the lower teeth (or in other words, the maxillary first molar occludes anterior to the buccal groove of the mandibular first ...
Class 2 elastics are used from the lower first molar to the upper canine tooth. [1] They can be used for many different reasons, such as Class 2 malocclusions, to reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, and to correct midline deviation and allow buccal movement of ...
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.
class 2 div 2 Deep bite. Overbite is often confused with overjet, which is the distance between the maxillary anterior teeth and the mandibular anterior teeth in the anterior-posterior axis. "Overbite" may also be used commonly to refer to Class II malocclusion or retrognathia, though this usage can be considered incorrect. This is where the ...
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 ]
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.
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. [8] 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.
