What is a Class 2 malocclusion?

A normal molar relationship exists but there is crowding, misalignment of the teeth, cross bites, etc. Class II Malocclusion. 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.

What is ideal occlusion?

What is GV Black classification?

How is Overjet measured?

Overjet is measured from the labial surface of the most prominent incisor to the labial surface of the mandibular incisor. Normally, this measurement is 2–4 mm (0.079–0.157 in). If the lower incisor is anterior to the upper incisors, the overjet is given a negative value.

What causes malocclusion?

Malocclusion is usually caused by problems with the shape or size of the jaw or teeth. A common cause is having too much or too little room in the jaw. If a child's jaw is small, the teeth may grow in crowded or crooked. If there's too much space in the jaw, the teeth may drift out of place.

Class II: Distocclusion (retrognathism, overjet, overbite) In this situation, the mesiobuccal cusp of the upper first molar is not aligned with the mesiobuccal groove of the lower first molar. Instead it is anterior to it. Usually the mesiobuccal cusp rests in between the first mandibular molars and second premolars.

How do you fix malocclusion without braces?
