Class II malocclusion.
origin (dental) - features (position distal d inf. with sup.) - etiology (d mesiogresion sup incisors. caries or premature loss of teeth d).
origin (skeletal) - characteristics (inadequate development or jaw position) - etiology (dl basic bone dysplasia maxillary and mandible, genetic factors, environmental factors, trauma, pathology of atm).
Class II is subdivided into:
division 1: facial features (convex, impotence lip, chin hypertonicity in open bite: proquelia sup. and lip inf. lip inverted)skeletal features (hipergonia, open mandibular plane, open bite, facial height increased) dental characteristics (d vestibuloversion incisors and extrusion sup. with diastema, d linguoversion incisors inf. crowding, anterior open bite
, Increased overjet, curve of spee checked)
divisio 2: facial features (convex or straight, alturafacial diminished, brachycephalic, labiomental groove marking retroquelia d lip sup.) skeletal features (deep bite, decreased alturafacial) dental characteristics (distal molar and canine relationship, sup central incisors. palatally e inf. lingualised) CONTINUOUS BACK

vestibuloversion canines, deep bite, in some cases occur in ant-inf crowding, overbite increased)
classification III skeletal defect in relation intermaxillary, maxillary or mandibular bone dysplasias.
origin (dental) - Characteristics (molar and canine mesial, anterior crossbite anterior deep bite, overjet negative) - etiology (trastonos eruptive tooth size, residual growth, pseudo prematurities = claseIII by anterior mandibular distalization or breathing difficulties).
origin (skeletal) - characteristics (mandibular protrusion, maxillary retrusion, combination) - etiology (genetics: Bone dysplasia linked to race).
INDIVIDUAL DENTAL Malposition:
version: (address) are inclined teeth around its horizontal axis can be lobby, lingual, meso, and distoversion.
progression: (position) the tooth is not in the position ql corresponds in the dental arch can be: Lobby, lingual, meso, and besides egresion and distogresion ingression.
rotations (direction) rotation about the central axis without displacement from the same rotation as may be called or distopalatal distobuccal face and mesiobuccal or midpalatal.
transposition: genetic exchange between two adjacent teeth of the dental arch
