Malocclusion

Abnormal or malpositioned relationship of the maxillary teeth to the mandibular teeth when they are in centric occlusion

Area where adjacent teeth physically touch

Contact area

Name for the curve of the occlusal plane

Curve spee

Masticatory

Chewing surface of the teeth

Quadrant

One fourth of dentition

Sextant

One sixth of the dentition

Succedaneous teeth

Permanent teeth that replace primary teeth

Maxillary

Upper jaw

Space between adjacent teeth

Interproximal

Curve space

Is the curvature formed by maxillary and mandibular arches in occlusion

Embrasure

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

Anterior

Front of the mouth

Position of teeth during chewing

Functional occlusion

How many teeth in primary dentition

20

Term that is used for the front teeth

Anterior

One-third portion of a tooth's surface is positioned towards the end of the root

Apical one third

Deciduous

Baby teeth

Referred as "cornerstone" of the dental arch

Canine

Classification is neutrickusion

Class 1

Junction of two tooth surfaces is

Line angle

Surface of the tooth that faces the tongue

Lingual

Mandibular

Lower jaw

Technical term for class 3 occlusion

Mesiocclusion

The mist posterior teeth

Molars

Dentition

Natural teeth in the dental arch

Two sets of teeth humans have in their lifetime

Primary and permanent

Four sections of the divided dental arches

Quadrant

Distal surface

Surface of the tooth distant from the midline

Mesial surface

Surface of the tooth towards the midline

Interpoximal space

The area between the proximal surfaces of two adjoining teeth in contact

Functional occlusion

When the teeth contact during biting and chewing movements

Occlusion

When the teeth of both arches are in contact

Centric occlusion

When there is maximum contact between the occluding surfaces of the maxillary and mandibular teeth
