A system developed by Dr. Edward H Angle to describe classification of Occlusion and Malocclusion.

Toward the front.

Division of the root nearest the tip of the root.

Tooth surface closest to the inner cheek.

Lengthwise diviston of the crown in a labial or buccolingual direction, sonsists of the facial or buccal/ labial/middle and lingual third.

Maximum contact between the occluding surface of the Maxillary and Mandibular teeth.

Division of the neck of the tooth.

Curved Inward

Area of the Mesial or Distal surface of a tooth that touches the adjacent tooth in the same arch.

Curved Outward

Curvature fromed by the Mandibullary and Manxillary arches in Occlusion.

Cross-arch curvature of the Occlusal Plane.

Pretainint to first dentition of 20 teeth often called "Baby Teeth" or Primary Teeth.

The natural teeth in the dental arch.

Surface of the tooth Distal from the Midline

A CLASS II Malocclusion in which the Mandibular of the Maxillarys first molar occludes (by more then the width of a premolar) Mesial to the Mesiobuccal groove of the Mandibular first Molar.

Triangular space in the gingival direction between the proximal surface of two adjoining teeth in contact.

Tooth surface that is closest to the face.

Contact between the teeth during biting and or chewing.

The chewing surface of the anterior teeth.

The area between adjacent tooth surfaces.

Facial surface closest to the lips.

The inclination of the teeth to extend facially, beyond the normal overlap of the incisal edge of the maxillary incisors over the mandibular incisors (bucktooth)

Junction of two walls in a cavity preperation.

Surface of the mandibular and maxillary theeth closest to the toung. (also known as Labial Surface)

Maxillary incisors are behind the mandibular incisors. (Underbite)

Occlusion that has diviated from a class I normal occlusion.

Lower Jaw.

The chewing surface of the teeth.

Upper Jaw.

The surface of the tooth closest to the midline.

Term used fro CLASS III Malocclusion.

Lengthwise division of the crown in a mesiodistal (front to back) Direction, Consisting of the Mesial/Middle and Distal Third.

Division of the root in the middle.

Mixture of Primary and Permanent teeth- between the ages of 6-12 uor until all the Primary teeth are lost.

An ideal Mesiodistal relationship between the Jaws and the Dental Arches.

The chewing surface of the Posterior Teeth.

The natural contact of the Maxillary and Mandibular teeth in all Positions.

Crosswise division of the crown that is braiel to the Occlusal or Incisal Surface, Consisting of the Occlusal/Middle and Cervical Third.

Lingual Surface of the Maxillary Teeth.

The Set of 32 Secondary teeth.

Angle formed by the Junction of three surfaces.

Toward the Back.

The first set of 20 Primary teeth "Baby Teeth"

The surface next to eachother when teeth are adjacent in the arch.

One quarter of the dentition.

One Sixth of the dentition.
