Term
| what trends do we need to know about proximal contours? |
|
Definition
| proximal contact areas correspond to the proximal height of contour (learn one, & you’ve learned the other) |
|
|
Term
| how do proximal contacts change as you move distally from the midline? |
|
Definition
|
|
Term
| when viewed from the incisal, how are proximal contact areas centered at the midline? |
|
Definition
|
|
Term
| when viewed from the occlusal, how are proximal contact areas centered at the posterior teeth? |
|
Definition
|
|
Term
| facially and lingually, how does the curvature of the cervical line (CEJ) appear? |
|
Definition
|
|
Term
| mesially and distally, how does the curvature of the cervical line (CEJ) appear? |
|
Definition
| towards the incisal/occlusal |
|
|
Term
| where is the amount of curvature of the cervical line normally greater? |
|
Definition
greater on
the mesial surface
than on the distal
surface (of each
tooth) |
|
|
Term
| how different is the amount curvature of the CEJ on adjacent teeth? |
|
Definition
|
|
Term
| where is the depth of curvature is greatest? |
|
Definition
| on central incisors and decreases posteriorly |
|
|
Term
| where is the depth of curvature is least? |
|
Definition
|
|
Term
| what are the functions of proximal contact areas? |
|
Definition
(1) stabilize teeth within the arch
(2) help prevent food impaction between teeth
(3) protect the interdental papilla as it diverts food facially and lingually |
|
|
Term
| when two adjacent teeth contact, how many embrasures are created? |
|
Definition
|
|
Term
| what are the four embrasures created when two adjacent teeth contact? |
|
Definition
(1) facial
(2) lingual (larger than facial)
(3) occlusal or incisal (often quite small)
(4) cervical/interproximal space/gingival (usually filled with gingiva) |
|
|
Term
|
Definition
| space between two adjacent teeth (not the result of a missing tooth) |
|
|
Term
| where is the most common location for a diastema? |
|
Definition
|
|
Term
| what are the five views for each tooth? |
|
Definition
(1) facial view
(2) lingual view
(3) mesial view
(4) distal view
(5) incisal/occlusal view |
|
|
Term
| what is the margin of the tooth? |
|
Definition
| the outline or the "silhouette" |
|
