Malocclusion
Exercise
Anteroposterior: Relationship of upper and lower first molar
*
Match the class / bite with picture
Hint:
Class I : Mesial Buccal cusp of Upper first molar aligns with Buccal groove of lower first molar
Class II : Mesial Buccal cusp of Upper first molar is Anterior with Buccal groove of lower first molar
Division 1: Maxillary Anterior teeth are proclined
Division 2: Maxillary Lateral Incisor is proclined
Class III : Mesial Buccal cusp of Upper first molar is posterior with Buccal groove of lower first molar
Overbite : How much incisor overlaps lower incisor vertically
samp
Crossbite : Upper teeth fit behind lower teeth
Open bite : Absence of vertical overlap
