|
Line Angle |
Two surfaces of a tooth that meet |
|
|
Point Angle |
Where 3 surfaces of a tooth meet Where two line angles meet |
|
|
Cervical |
Surface on gum line |
|
|
Tooth Surface Naming Convention |

|
|
Palmer's Notation |
Break teeth into 4 quadrants Go from mesial to distal teeth No double digits Graphic Image denotes which quadrant it is |
|
|
International Notation |
Break into 4 quadrants (Right Maxillary, Left Maxillary, Left Mandibular, Right Mandibular) Use Quadrant number as the first number of the tooth's identification Second number is mesial to distal Always double digits |
|
|
Incisors Function During Mastication |
Used to bite food |
|
|
Canine |
Used for ripping and tearing food apart Holding food Sharpest teeth |
|
|
Premolar/Bicuspid Function |
Chewing and grinding food |
|
|

Chewing and grinding food |
|
|
Anterior Teeth Shape |
Triangular |
|
|
Maxillary Posterior Teeth Shape |
Trapezoidal |
|
|
Mandibular Posterior Teeth Shape |

|
|
Characteristics that contribute to self cleansing |
Proximal Contacts Interproximal Spaces Embrasures Facial and lingual contours Curvature of the Cementoenamel Junction |
|
|
Teeth Features That Indirectly Contribute to Stability During Function |
Cusp Form Proportions of crowns and roots Root form Anchorage and angles at which teeth are set in the jaws |
|
|
Interproximal Spaces |
Triangular in shape Papillary gingiva/Interdental papilla forms the sides and base When there is loss of gingiva, there is increase in size |
|
|
Proximal Contact Areas |
Consist of mesial and distal contact areas Proper contacts prevents food impaction Prevent trauma to the papillary gingiva Provide support for the teeth Improper contacts can contribute to periodontal disease |
|
|
Embrasures/Spillways |
Facial, lingual, incisal or occlusal to contact area Prevent food impaction Dissipate occlusal forces Allows self cleansing Gigival stimulation |
|
|
Anterior Teeth Labial and Lingual Embrasure Size Comparison |
Labial and Lingual embrasure are the same size
|
|
|
Posterior Teeth Buccal and Lingual Embrasure Size Comparison |
Buccal embrasure is narrower than the Lingual embrasure |
|
|
Incisal and Occlusal Embrasures Size |
Size increases from anterior to posterior |
|
|
Cervical (gingival) Embrasures Size |
Size decreases from anterior to posterior |
|
|
Function of Facial and Lingual Contours |
Determines position of tongue and lips Directing food at appropriate angle Gingival stimulation Prevent food impaction |
|
|
Height of Contour |
Allow for adequate gingival health help form the mesial and distal contact area Should be occlusal to Cementoenamel Junction |
|
|
Lingual Height of Contour for Anterior Teeth |
Cervical 1/3 |
