Dentition analyses are systems of tooth and jaw measurement used in orthodontics to understand arch space and predict any malocclusion (mal-alignment of the teeth and the bite). Example systems of dentition analysis are listed below.
Total space analysis (cast + cephalometric + soft tissue)
Dental arch analysis
Intermolar Width - It is the distance between the mesiobuccal cusp tip points of the first permanent molars
Intercanine Width - It is the distance between the tip of the cusp from canine to canine.
Arch Length - It is the distance from the line perpendicular to the mesiobuccal cusp tips of the first permanent molars to the midpoint between the mesioincisal points of the central incisors.
Arch Perimeter - It is the distance from mesial contact of a permanent molar on one side to the mesial contact of permanent molar on the other side, with the line connecting the buccal/incisor tip points in the intervening teeth.
