Term | Definition |
Angle's classification | System developed by Dr. Edward H. Angle to describe and classify occlusion and malocclusion. |
Anterior | Towards 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 division of the crown in a labial or buccolingual direction, consisting of the facial or buccal/labial third, middle third, and lingual third. |
Centric occlusion | Maximum contact between the occluding surfaces of the maxillary and mandibular teeth. |
Cervical third | Division of the root nearest 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 formed by the maxillary and mandibular arches in occlusion. |
Curve of Wilson | Cross-arch curvature of the occlusal plane. |
Deciduous (duh-SID-yoo-us) | Pertaining to first dentition of 20 teeth; often called "baby teeth" or primary teeth. |
Dentition (den-TI-shun) | Natural teeth in the dental arch. |
Distal surface | Surface of tooth distant from the midline. |
Distoclusion (DIS-toe-kloo-shun) | 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. |
Embrasure (em-BRAY-zhur) | Triangular space in a gingival direction between the proximal surfaces of two adjoining teeth in contact. |
Facial surface | Tooth surface closest to the face. Facial surfaces closest to the lips are called labial surfaces, and facial surfaces closest to the inner cheek are called buccal surfaces; therefore, the term facial can be substituted for labial and buccal, and vice ver |
Functional occlusion | Contact of the teeth during biting and chewing movements. |
Incisal surface | Chewing surface of anterior teeth. |
Interproximal (in-tur-PROK-si-mul) space | 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. |
Line angle | Junction of two walls in a cavity preparation. |
Lingual surface | Surface of mandibular and maxillary teeth closest to the tongue; also called palatal surface. |
Linguoversion | Position in which the maxillary incisors are behind the mandibular incisors. |
Malocclusion (MAL-o-kloo-zhun) | Occlusion that is deviated from a class I normal occlusion. |
Mandibular (nam-DIB-you-ler) | The lower jaw. |
Masticatory (MAS-ti-kuh-tor-ee) surface | The chewing surface of the teeth. |
Maxillary (MAK-si-lar-ee) | The upper jaw. |
Mesial surface | Surface of the tooth toward the midline. |
Mesioclusion (MEE-zee-oe-kloo-zhun) | Term used for class III malocclusion. |
Mesiodistal division | Lengthwise division of the crown in a mesiodistal (front-to-back) direction, consisting of the mesial third, middle third, and distal third. |
Middle third | Division of the root in the middle. |
Mixed dentition | 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. |
Neutroclusion | An ideal mesiodistal relationship between the jaws and the dental arches. |
Occlusal surface | Chewing surface of posterior teeth. |
Occlusion (oe-KLOO-zhun) | The natural contact of the maxillary and mandibular teeth in all positions. |
Occlusocervical division | Crosswise division of the crown that is parallel to the occlusal or incisal surface, consisting of the occlusal third, middle third, and cervical third. |
Palatal surface | Lingual surface of maxillary teeth. |
Permanent dentition | The set of 32 secondary teeth. |
Point angle | Angle formed by the junction of three surfaces. |
