A system developed by Dr. Edward H Angle to describe classification of Occlusion and Malocclusion.
ANTERIOR
Toward the front.
APICAL THIRD
Division of the root nearest the tip of the root.
BUCCAL SURFACE
Tooth surface closest to the inner cheek.
BUCCOLINGUAL DIVISION
Lengthwise diviston of the crown in a labial or buccolingual direction, sonsists of the facial or buccal/ labial/middle and lingual third.
CENTRIC OCCLUSION
Maximum contact between the occluding surface of the Maxillary and Mandibular teeth.
CERVICAL THIRD
Division of the neck of the tooth.
CONCAVE
Curved Inward
CONTACT AREA
Area of the Mesial or Distal surface of a tooth that touches the adjacent tooth in the same arch.
CONVEX
Curved Outward
CURVE OF SPEE
Curvature fromed by the Mandibullary and Manxillary arches in Occlusion.
CURVE OF WILSON
Cross-arch curvature of the Occlusal Plane.
DECIDUOUS
Pretainint to first dentition of 20 teeth often called "Baby Teeth" or Primary Teeth.
DENTITION
The natural teeth in the dental arch.
DISTAL SURFACE
Surface of the tooth Distal from the Midline
DISTOCLSION
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.
EMBRASURE
Triangular space in the gingival direction between the proximal surface of two adjoining teeth in contact.
FACIAL SURFACE
Tooth surface that is closest to the face.
FUNCTIONAL OCCLUSION
Contact between the teeth during biting and or chewing.
INCISAL SURFACE
The chewing surface of the anterior teeth.
INTERPROXIMAL
The area between adjacent tooth surfaces.
LABIAL SURFACE
Facial surface closest to the lips.
LABIOVERSION
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)
LINE ANGLE
Junction of two walls in a cavity preperation.
LINGUAL SURFACE
Surface of the mandibular and maxillary theeth closest to the toung. (also known as Labial Surface)
LINGUOVERSION
Maxillary incisors are behind the mandibular incisors. (Underbite)
MALOCCLUSION
Occlusion that has diviated from a class I normal occlusion.
MANDIBULAR
Lower Jaw.
MASTICATORY SURFACE
The chewing surface of the teeth.
MAXILLARY
Upper Jaw.
MESIAL SURFACE
The surface of the tooth closest to the midline.
MESIOCLUSION
Term used fro CLASS III Malocclusion.
MEDSIODISTAL DIVISION
Lengthwise division of the crown in a mesiodistal (front to back) Direction, Consisting of the Mesial/Middle and Distal Third.
MIDDLE THIRD
Division of the root in the middle.
MIXED DENTITION
Mixture of Primary and Permanent teeth- between the ages of 6-12 uor until all the Primary teeth are lost.
NEUTROCLUSION
An ideal Mesiodistal relationship between the Jaws and the Dental Arches.
OCCLUSAL SURFACE
The chewing surface of the Posterior Teeth.
OCCLUSION
The natural contact of the Maxillary and Mandibular teeth in all Positions.
OCCLUSOCERVICAL DIVISION
Crosswise division of the crown that is braiel to the Occlusal or Incisal Surface, Consisting of the Occlusal/Middle and Cervical Third.
PALATAL SURFACE
Lingual Surface of the Maxillary Teeth.
PREMANENT DENTITION
The Set of 32 Secondary teeth.
POINT ANGLE
Angle formed by the Junction of three surfaces.
POSTERIOR
Toward the Back.
PRIMARY DENTIOTION
The first set of 20 Primary teeth "Baby Teeth"
PROXIMAL SURFACE
The surface next to eachother when teeth are adjacent in the arch.
