system developed by Dr. Edward H. Angle to describe and classify occlusion and malocclusion | Angle's Classification |
toward the front | Anterior |
division of the root nearest the tip of the root | Apical third |
tooth surface closest to the inner cheek | Buccal surface |
lenthwise division of the crown in a labial or buccolingual direction, consisting of the facial or buccal/labial third, middle third, and lingual third. | Buccolingual division |
maximum contact between the occluding surfaces of the maxillary and mandibular teeth | centric occlusion |
division of the root nearest the neck of the tooth | cervical third |
curved inward | concave |
area of the mesial or distal surface of a tooth that touches the adjacent tooth in the same arch | contact area |
curved outward | convex |
curvature formed by the maxillary and mandibular arches in occlusion | Curve of Spee |
cross-arch curvature of the occlusal plane | Curve of Wilson |
pertaining to first dentition of 20 teeth; often called "baby teeth" or primary teeth. | Deciduous |
natural teeth in the dental arch | dentition |
surface of tooth distant from the midline | distal |
a class II malocclusion in which the mesiobuccal cusp of the maxillary first molar occludes (by more than the width of a premolar) mesial to the mesiobuccal groove of the mandibular first molar | Distoclusion |
triangular space in a gingival direction between the proximal surfaces of two adjoining teeth in contact | Embrasure |
tooth surface closest to the face.facial surfaces closest to the lips are called labial surfaces, & facial surfaces closest to the inner cheek are called buccal surfaces; therefore, the term facial can be substituted for labial and buccal, and vice versa | facial surface |
contact of the teeth during biting and chewing movements | functional occlusion |
chewing surface of anterior teeth | incisal surface |
the area between adjacent tooth surfaces | interproximal space |
facial surface closest to the lips | labial surface |
inclination of the teeth to extend facially beyond the normal overlap of the incisal edge of the maxillary incisors over the mandibular incisors | labioversion |
junction of two walls in a cavity preparation | line angle |
surface of mandibular and maxillary teeth closest to the tongue; also called palatal surface | lingual surface |
position in which the maxillary incisors are behind the mandibular incisors | linguoversion |
occlusion that is deviated from a class I normal occlusion | Malocclusion |
the lower jaw | Mandibular arch |
chewing surface of the teeth | Masticatory surface |
the upper jaw | Maxillary arch |
surface of tooth toward the midline | mesial surface |
term used for class III malocclusion | Mesioclusion |
lengthwise division of the crown in a mesiodistal (front-to-back) direction, consisting of the mesial third, middle third, and distal third | Mesiodistal division |
division of the root in the middle | middle third |
a mixture of permanent teeth and primary teeth that occurs until all primary teeth have been lost, usually between the ages of 6 and 12 | Mixed dentition |
an ideal mesiodistal relationship between the jaws and the dental arches | Neutroclusion |
chewing surface of posterior teeth | occlusal surface |
the natural contact of the maxillary and mandibular teeth in all positions | occlusion |
crosswise division of the crown that is parallel to the occlusal or incisal surface, consisting of the occlusal third, middle third, and cervical third | occlusocervical division |
lingual surface of maxillary teeth | palatal surface |
angle formed by the junction of three surfaces | point angle |
toward the back | posterior |
the first set of 20 primary teeth | primary dentition |
the surfaces next to each other when teeth are adjacent in the arch | proximal surfaces |
one quarter of the dentition | quadrant |
one sixth of the dentition | sextant |
permanent teeth that replace the primary teeth | succedaneous |
a two-cusp type of mandibular second premolar | bicanineate |
divided into two | bifurcated |
area in which two roots divide | bifurcation |
external vertical bony ridge on the labial surface of the canines | canine eminence |
most prominent developmental groove on the posterior teeth | central groove |
raised, rounded area on the cervical third of the lingual surface | cingulum |
major elevation on the masticatory surfaces of canines and posterior teeth | cusp |
the fifth supplemental cusp found lingual to the mesiolingual cusp | Cusp of Carabelli |
a space between two teeth | diastema |
wide, shallow depression on the lingual surfaces of anterior teeth | fossa |
area between two or more root branches | furcation |
slight ridges that run mesiodistally in the cervical third of the teeth | imbrication lines |
ridge on permanent incisors that appears flattened on labial, lingual, or incisal view after tooth eruption | incisal edge |
sloping areas between the cusp ridges | inclined cuspal planes |
rounded enamel extension on the incisal ridges of incisors | mamelon |
a developmental groove that crosses a marginal ridge and serves as a spillway, allowing food to escape during mastication | marginal groove |
rounded, raised border on the mesial and distal portions of the lingual surfaces of anterior teeth and the occlusal table of posterior teeth | marginal ridge |
teeth located in the posterior aspect of the upper and lower jaws | molars |
study of form and shape, as of the teeth | Morphology |
pertaining to a permanent tooth that does not replace a primary tooth | Nonsuccedaneous |
incisors with a pointed or tapered shape | pegged laterals |
permanent teeth that replace primary teeth | succedaneous teeth |
a developmental groove that separates a marginal ridge from the triangular ridge of a cusp | Triangular groove |
a three-cusp type of mandibular second premolar | tricanineate |
divided into three | trifurcated |
area in which three roots divide | trifurcation |
area or process of discovering tooth imperfections or decay | detection |
