2. Measurements LENGTH OF CROWN 10 mm LENGTH OF ROOT 17 mm MESIODISTAL DIAMETER OF CROWN 7.5 mm MESIODISTAL DIAMETER OF CROWN AT CERVIX 5.5 mm LABIOLINGUAL DIAMETER OF CROWN 8 mm LABIOLINGUAL DIAMETER OF CROWN AT CERVIX 7 mm CURVATURE OF CERVICAL LINE—MESIAL 2.5 mm CURVATURE OF CERVICAL LINE—DISTAL 1.5 mm Dr. Zain Sajad

3. Distally, the outline of the crown is usually concave between the cervical line and the distal contact area. Mesially , the outline of the crown may be convex or slight concavity from the cervix to the center of the mesial contact area. The cusp has a mesial slope and a distal slope, the mesial slope is shorter .Both slopes show a tendency toward concavity Distal Mesial Labial aspect Dr. Zain Sajad

4. Labial aspect MESIALLY Distal Dr. Zain Sajad the outline of the crown may be convex or slight concavity from the cervix to the center of the mesial contact area . The center of thecontact area at the junction of middle and incisal thirds. DISIALLY the outline of the crown is Usually concave between the cervical line and the distal contact area. The distalcontact area is usually at the center of the middle third of the crown. The cusp has a mesial slope and a distal slope, the mesial slope is shorter . Both slopes show a tendency toward concavity

5. Step by Step Draw the Midline Put zero point and continue to complete the Crown Length = 1 mm Complete the root length = 17 mm The mesiodistal width at cervix = 5.5 mm (2.75|2.75) Mesial curvature of the cervical line : 2.5 mm Distally : 1.5 mm The mesiodistal width at widest area = 7.5 mm (3.75|3.75) The widest area is 4.5 mm from the zero point The Contact area determined from the widest area its 1.5 down mesially and 0.5 up distally Connect the points of the crown first then the root Distally , the outline of the crown is usually concave between the cervical line and the distal contact area. Mesially , the outline of the crown may be convex or slight concavity from the cervix to the center of the mesial contact area. How to draw Dr. Zain Sajad

7. Note : the same as labial Aspect but the Shape And Measurement Are Inverted ,There are two concavities present , they are called mesial and distal lingual fossae Mesial Distal Lingual aspect Dr. Zain Sajad

8. Step by Step Draw the Midline Put zero point and continue to complete the Crown Length = 10 mm Complete the root length = 17 mm Labiolingual diameter of the crown at cervix = 7 mm (3.5|3.5) Mesial curvature of the cervical line : 2.5 mm Labiolingual diameter at widest area = 8 mm (4|4) The widest area is 3 mm from the cervical Line The incisal edge is 1mm Labialy from the Midline Connect the points of the crown first then the root How to draw Dr. Zain Sajad Mesial aspect

11. Note : The same as Mesial Aspect but the Shape and Measurement (Distal curvature of the cervical line : 1.5 mm) Are Inverted According to Tooth position Distal aspect Dr. Zain Sajad
