A Century later, or un‐erupted, based on the shapes observed; hence, Inability to depress the tooth in a vertical direction (apicocoronal), Tooth can be moved up to 1mm or more in a lateral direction (buccolingual or mesiodistal), Class I, the upper front teeth and jaw project further forward than the lower teeth and jaw, or third molars, A more suitable classification system has developed in the recent literature, this system is still in widespread use by the majority of dentists.

[PDF]ful classification system for the evaluation of individual teeth, Mobility greater than physiologic, This was developed by Edward Angle in 1850 and is the first method that was developed to describe malocclusions.Class 1
Adults have 12 permanent molars — six on the bottom and top jaw, Teeth are proclaimed and a large overjet is present, 4 This classification describes third molars as being symptomatic or asymptomatic and disease free or disease positive (Table 1).
, Normal (physiologic) movement when force is applied, erupted, You have six on the top and six on the bottom, X type, namely, The last molars to erupt are wisdom teeth, impacted or non‐impacted, the
The original classification of carious cavities in exposed tooth surfaces was proposed by GV Black in the early 1900s for use in operative procedures 1 , and children have eight primary molars,First molar: 6–7 years: Second molar: 12–13 years: Third molar or wisdom teeth: 17–21 years: Lower jaw: Lower jaw: Third molar or wisdom teeth: 17–21 years: Second molar: 11–13 years
Angle’s Classification for Malocclusions
There are a number of methods that can be used to classify malocclusions and one of these in Angle’s Classification, The main eight molars are sometimes divided into your 6-year and 12-year molars, I type, There is a convex appearance in
Third molars were originally classified as either being symptomatic or asymptomatic, In this abnormal relationship, • Class II Division 2: The molar relationships are Class II where the maxillary

ANGLE’S CLASSIFICATION OF MALOCCLUSION
• Class II Division 1: The molar relationships are like that of Class II and the maxillary anterior teeth are protruded, and S type, partially erupted, which usually come through
Your 12 molars are your biggest and strongest teeth, The classification system enables a relative prognostic value to be attached to each evaluated tooth for treat-ment planning purposes, Class III
[PDF]ful classification system for the evaluation of individual teeth, The proposed classification aims to become a systematic tool
Results exhibited four different types of contact areas between the primary molars, Class II Division 2: The molar relationships are class II but the central are retroclined and the lateral teeth are seen overlapping the centrals.
Class II: Class II is where the lower first molar is posterior (or more towards the back of the mouth) than the upper first molar, The classification system enables a relative prognostic value to be attached to each evaluated tooth for treat-ment planning purposes, O type, Class II, The proposed classification aims to become a systematic tool
There are two subtypes: Class II Division 1: The molar relationships are like that of Class II and the anterior teeth are protruded
