Dental science Flashcards
Centric Occlusion
Maximum contact between the occluding surfaces
Contact Area
Area mesial or distal surface of a tooth that touches the adjacent tooth
Concave
Curve inward
Abrasion
Mechanical (wearing away of teeth) by abnormal stressors
Curve of spee
Curvature formed be Maxillary and mandibular arch
Foramen
Short circular opening through bone
Height of contour
Widest point on a specific surface of the crown
Middle third
Division of the root in the middle
Sextant
1/6 th of the dentition tooth
Bifurcated
Divided into 2
Alveolar bone
Bone that forms the sockets for teeth
Alveolar Process
Portion of the Maxillary bone that form the support for teeth of the Max. Arch
Alveolar Crest
Highest point of alveolar ridge
Alveolar Socket
Cavity that’s surrounds the root of a tooth
Apical foramen
Natural opening in the root
Cementum
Specialized connective tissue, that covers root of tooth
Anatomic Crown
Portion of the tooth that is covered with enamel
Condyloid process
The Posterior process of each ramus: articulates with fossa in the temporal bones to form the TMJ ( mandibular condyle)
Dental papilla
Gingiva between the teeth
Exfoliation
Process of shedding primary teeth
Free Gingiva
Gingiva that forms gingival sulcus
Gingiva
Part of the gum tissue that surrounds the teeth and alveolar bone
Gingiva sulcus
Space between the free Gingiva and tooth structure
Histology
The study of the structure and function of body tissue
Humulus
Hook shape process
Lamina dura
Thin, compact bone that lines the alveolar socket
Margins
The edge of a tooth prep where the prep ends and normal tooth anatomy is left
