CRE

Question 1

Alignment/ Rotations

Answer 1

0 - 0.5 mm = 0 points
0.6 - 1 mm = 1 point
> 1 mm = 2 for each tooth

Question 2

Marginal Ridges

Answer 2

0 - 0.5 mm = 0 points
0.6 - 1 mm = 1 point (for each interprox contact between posterior teeth)
> 1 mm = 2 for each tooth

*** Do not include the canine-premolar contact. DO not include the distal of lower 1st premolar

Question 3

Buccolingual Inclination

Answer 3

0 - 1 mm = 0 points
1.1 -2 mm = 1 (for each posterior tooth)
> 2 mm = 2 for each tooth

***Do not score the mandibular 1s premolars nor the distal cusps of the second molars

Question 4

Overjet

Answer 4

*Anterior teeth must be contacting

0 - 0.5 mm = 0 points
0.6 - 1.5 mm = 1 (for each maxillary tooth)
> 1.5 mm = 2 for each tooth

Question 5

Occlusal Relationship

Answer 5

=/< 1 mm = 0 points

1.1 - 2 mm = 1 (for each maxillary tooth from the canines to the second molars)

> 2 mm = 2

Question 6

Root Angulation

Answer 6

Parallel = 0
Not Parallel = 1
Root contacting adjacent tooth = 2 (for each occurrence)

***Check to see if it’s a CBCT. If it is, score the canine. If not, then don’t.
