The system developed by Dr. Edward Angle to describe and classify occlusion and malocclusion. | Angle's Classification |
Term used to describe toward the front. | Anterior |
Term used to describe the division of the root nearest the tip of the root. | Apical Third |
Term used to describe the surface closest to the inner cheek. | Buccal |
What is the term used to describe the lengthwise division of the crown in a labial or buccolingual direction? | Buccolingual Division |
Term used to describe the maximum contact of maxillary and mandibular occluding surfaces. | Centric Occlusion |
Term used to describe the division of the root nearest the neck of the tooth. | Cervical Third |
To curve inward. | Concave |
The area of the mesial or distal surface of a tooth that touches the adjacent tooth in the same arch. | Contact Area |
To curve outward. | Convex |
The curvature formed by the maxillary and mandibular arches in occlusion. | Curve of Spee |
The cross-arch curve of the occlusal plane. | Curve of Wilson |
This term pertains to the first (primary) dentition, generally consisting of 20 teeth. | Deciduous |
Term given to the natural teeth in the dental arch. | Dentition |
Term given to the surface of a tooth distant from the midline. | Distal |
Term given to a class II malocclusion in which the mesiobuccal cusp of the maxillary first molar occludes mesial to the mandibular first molar; mandibular arch is in a distal relationship to maxillary. | Distoclusion |
The triangular space in a gingival direction between the proximal surfaces of 2 adjacent teeth in contact. | Embrasure |
Term given to the tooth surface of anterior teeth that touch the lips (labial). | Facial |
Term used to describe the contact of the teeth during biting and chewing movements. | Functional Occlusion |
Term used to describe the chewing surface of the anterior teeth. | Incisal |
Term given to the area between adjacent tooth surfaces. | Interproximal |
Term given to the facial surface closest to the lips. | Labial |
Term to describe the inclination of the teeth to extend facially beyond the normal overlap of the incisal edge, maxillary over mandibular. | Labioversion |
Term used to describe the junction of 2 tooth surface walls. | Line Angle |
Term given to the surface of the maxillary and mandibular teeth closest to the tongue. | Lingual |
Term given to the position in which the maxillary incisors are behind the mandibular incisors; class II . | Linguoversion |
Term used for an occlusion that is deviated from a class I normal occlusion. | Malocclusion |
Term pertaining to the lower jaw. | Mandibular |
Term used to describe the chewing surface of the teeth. | Masticatory Surface |
Term given to the tooth surface toward the midline. | Mesial |
Term used to describe a class III malocclusion; mandible is in an abnormal mesial relationship to the maxilla. | Mesioclusion |
Term used to describe the lengthwise division of the crown in a mesiodistal direction. | Mesiodistal Division |
Term used to describe the division of the root in the middle. | Middle Third |
Term used to describe a dentition consisting of both primary and permanent teeth. | Mixed Dentition |
What is the name given to the residue from epithelial tissue on newly erupted crowns that may become extrinsically stained? (can be removed by a gentle coronal polish) | Nasmyth's Membrane |
Term given to describe the ideal mesiodistal relationship between the jaws and dental arches, Class I. | Neutroclusion |
Term given to the chewing surfaces of the posterior teeth. | Occlusal |
What is the term for the relationship between the maxillary and mandibular teeth when in a closed position? | Occlusion |
Term used to describe the crosswise division of the crown that is parallel to the occlusal or incisal surface, dividing into occlusal/middle/cervical thirds. | Occlusocervical Division |
Term for the lingual surface of the maxillary teeth. | Palatal Surface. |
What is the term given to a set of 32 secondary teeth? | Permanent Dentition |
Term given to the angle formed by the junction of three surfaces. | Point Angle |
Term given to the surface toward the back. | Posterior |
What is the term given to the first set of 20 primary teeth? | Primary Dentition |
Term used to describe the surfaces next to each other when teeth are adjacent in the arch. | Proximal Surfaces |
Term used to describe 1 quarter of the dentition. | Quadrant |
Term used when the dental arches are broken into 6 sections rather than 4. | Sextant |
Term used to describe permanent teeth that replace primary teeth. | Succedaneous |
