Angle?
Two types? Angulation for Calculus Removal? |
-formed by two straight lines that meet at an endpoint
-90 and 45 degree -more than 45 less than 90 |
|
|
Parallel Lines?
Perpendicular Lines? Shank Position? |
-lines that run in same direction, never intersect
-two lines that intersect to form a 90degree - parallel to the long axis of a tooth |
|
|
3 Orientation of Lines?
|
- vertical= up and down
-oblique= corner to corner -horizontal= across a.k.a circumferential strokes |
|
|
Cross Section?
|
- exposed by cutting through an object, usually at a right angle
|
|
|
Millimeter?
|
- one thousands of a meter or 0.0394inch
- mm -anatomic features of teeth are often measured in mm |
|
|
Periodonatal Probe?
Pockets Depth? |
- instrument similar to mini ruler
- marked in mm units - used for making intraoral measurements -4mm or greater |
|
|
Long Axis?
|
- imaginary straight line that pass through the center of a tooth and divides it symmetrically
- long axis is used at reference point |
|
|
Apical?
Coronal? |
- moved toward the tooth apex
-moved toward the tooth crown |
|
|
Midline?
Line Angles? |
- anterior tooth can be divided by this imaginary line
-intrumentation of anterior is initiation of midline -posterior tooth can be divided -imaginary line formed where 2 tooth surfaces meet |
|
|
4 Line Angles?
|
-1. Mesiofacial line angle
2. Distofacial line angle 3. Mesiolingual line angle 4. Distolingual line angle |
|
|
Aspect?
Two Kinds of Aspects, and subdivisions? |
- tooth, sextant, quadrant, or dental arch are divided into 2 Aspects
-Facial= 3 areas. 1)distofacial 2)facial surface 3)mesiofacial area -Lingual= 3 areas 4)distolingual 5)lingual area 6)mesiolingual area |
|
|
Sextant?
How many Anterior & Posterior? |
- dentition divided into 6 areas
- 2 Anterior, 4 Posterior |
|
|
All Sextants?
|
-1) Mixillary right posterior
2) Maxillary anterior 3) Maxillary left posterior 4) Mandibular left posterior 5) Mandibular anterior 6) Mandibular right posterior |
