Study Notes
Dental Anatomy Overview
- Two sets of teeth: primary (deciduous) and permanent (succedaneous).
- Primary dentition comprises 20 teeth; permanent dentition includes 32 teeth.
Dental Arch Division
- Dental arches are divided into four sections known as quadrants.
Types of Teeth
- Front teeth are referred to as anterior teeth; back teeth are called posterior teeth.
- Four types of teeth include incisors, canines, premolars, and molars.
- Canines are considered the "cornerstone" of the dental arch.
Tooth Surfaces and Spaces
- Teeth possess five surfaces: facial, lingual, masticatory, mesial, and distal.
- The area between adjacent teeth is called interproximal surfaces.
- The contact area refers to where adjacent teeth physically touch.
- Embrasure is a triangular space located toward the gingiva between adjacent teeth.
Tooth Junctions and Positions
- The junction of two tooth surfaces is termed contact.
- The apical third of a tooth is the portion nearest the end of the root.
Occlusion Concepts
- Occlusion describes the position of teeth during chewing movements.
- Malocclusion is the term for teeth that are in poor occlusion.
- Class III malocclusion is known as mesioclusion.
- Neutroclusion is classified as Class I, indicating an ideal mesiodistal relationship between the jaws and dental arches.
- The curve of the occlusal plane is referred to as the curve of Spee.
