Drawing Steps
Note : Scale Drawing Each 1 mm in table = 1 medium square in graph paper.
Tips : Drawing with tracing paper is helpful.
Labial Surface
1- Tooth name • Full name = Dentition + Arch + Side + Tooth
2- Surface name
• Labial surface.
Midline
• To identify the mesial and distal surfaces. Distal Mesial
3-
line
4-
Cervical
• To identify the crown and root. Root Crown
5-
Measurements : Table 6-1 • A- Length of crown.
• B- Length of Root. 5- Measurements : Table 6-1
C- Thirds division : • Cervico- Incisal = Cervical + middle + incisal • 3.5 mm for each third.
5- Measurements : Table 6-1
• D- Mesiodistal diameter of crown at cervical line.
• E- Mesiodistal diameter of crown.
• Location of contact area.
Mesial = within incisal third near mesioincisal angle. Distal = at junction between incisal and middle third . 4.25
4.25
5- Measurements : Table 6-1
6- Draw the surface. • Connect between the points (Mesial outline) slight convex . 4.25 4.25
6- Draw the surface.
• Connect between the points (Distal outline) more convex. 4.25 4.25
• Connect between the points (Root) cone + Blunt end . 4.25 4.25 6- Draw the surface.

6- Draw the surface.
• Connect between the points (Labial outline) from crest of curvature to incisal ridge slightly convex .
6- Draw the surface.
• Connect between the points (Lingual outline) convex at cingulum then concave at mesial marginal ridge then convex at incisal edge.
6- Draw the surface.
• Connect between the points (Root).
