Class II Malocclusions can be divided into a division 1 and 2 malocclusion.Class II division 1 is characterized by big overjet while a class II division 2 malocclusion is characterized by a deep overbite.
Class II Malocclusion has two divisions to describe the position of the anterior teeth.
ƒClass II Division 1: Is when the maxillary anterior teeth are proclined and a large overjet is present.
ƒClass II Division 2: Is where the maxillary anterior teeth are retroclined and a deep overbite exists.
A malocclusion where the molar relationship shows the buccal groove of the mandibular first molar distally positioned when in occlusion with the mesiobuccal cusp of the maxillary first molar.
Class II malocclusion very rarely occurs due to spontaneous distalizing of lower molar.Usually it is a result of a mesializing,mesial version or mesial rotation of the upper molar.
The patient exhibits a class II molar relation (Distobuccal cusp of the upper first permanent molar occludes in the buccal groove of the lower first permanent molar The molar relation can vary from an end on molar to one that is a full-fledged class II
Features •malocclusion is the presence of proclined maxillar anteriors with resultant increased overjet. •Increased overbite and excessive curve of Spee. •Have a short hypotonic upper lip; also patient place lower lip against palatal surface of the upper incisors this is called lip trap. •Patient lack an anterior lip seal due to the short upper lip. •Narrow upper arch which predisposes to posterior crossbite.
Class II Division 2 Malocclusion
The class II, division 2 malocclusion is a condition characterised by a class II molar relationship with retroclined upper centrals that are overlapped by the lateral incisors
Features •Molars in distoocclusion •Retroclined central incisors and rarely of other anteriors as well. •Deep overbite •Pleasing straight profile •Broad square face •Backward path of closure •Absence of abnormal muscle activity
According to Isaacson et al ,2003 :63, A class II division I malocclusion may be defined as one in which the lower incisor edges occlude palatal to the cingulum plateau of the upper incisor. The upper incisors are either of average axial inclination or proclined. The overjet in increased and the overbite is usually increased (although it may be incomplete). The buccal segment relationship reflects the severity of the malocclusion but may be influenced by crowding or spacing in the either of the arches.
A Class II malocclusion is a condition in which the upper teeth protrude past the lower teeth. This is commonly referred to as an overbite. The causes are varied, so the treatment will depend upon the cause as well as the severity of the malocclusion. treatment is to commence as early as possible. A Class II arrangement has two divisions: division 1 and 2 malocclusion. In division 1,a big overjet defines it while a class II division 2 malocclusion a deep overbite defines it.
Factors that characterise class II malocclusion using a twin block are as follows 1.The Position, this position is characterised by the mandibular block and is important in the treatment of a deep overbite 2.The Extension, the block should extend distally to the buccal cusp of the mandibular 2nd pre-,olar or deciduous molar stopping short of the marginal ridge 3.The Angulation, the inclined plane is angled from the mesial surface of teh 2nd premolar or deciduous molar at 70 degrees to the occusal plane 4.The Occlusal Planesthe mandibular block covers the occlusal surfaces of the mandibular pre-molar or deciduous molars to occlude with teh inclined plane on the maxillary twin block
Class II malocclusion group is characterised by a ClassII molar relation where the disto-buccal cusp of the upper first permanent molar occludes in the buccal groove of the lower first permanent molar. Has been stated by all the Class II malocclusion has two sub-divisions Class II, division 1 which is characterized by proclined upperincisors with resultant increase in overjet. Class II division 2 as in Class II division 1 malocclusion this division exhibits a Class II molar relationship, its classical feature is the presence of lingually inclined upper central incisors and labially tipped upper lateral incisors overlapping the central incisors.
In Class II, Division I there is an overjet of all the upper incisors; in the Class II, Division II the upper central incisors are closely applied to the lower incisors while the upper lateral incisors overlap the centrals.
A malocclusion where the molar relationship shows the buccal groove of the mandibular first molar distally positioned when in occlusion with the mesiobuccal cusp of the maxillary first molar. Class II malocclusion is divided into two divisions.
Division 1: This is when the maxillary anterior teeth are proclined and causes a large overjet to occur. This can be caused by thumb sucking or genetics.
Division 2: This division is present when the maxillary anterior teeth are retroclined and causes a large overbite to be present.

Class II- the mesiobuccal cusp of the maxillary first molar lies anterior to the buccal groove of the mandibular first molar.
