ALIGNMENT/ROTATIONS

0.5 – 1 mm = 1 for each tooth

      > 1 mm =  2 for each tooth

OCCLUSAL CONTACTS

   0 mm = satisfactory

≤ 1 mm = 1 (for each posterior tooth

> 1 mm = 2    out of contact)

** Do not score diminutive distolingual cusps of the maxillary 1st and 2nd molars, nor lingual cusps of the mandibular first premolars. Maximum of 2 points per tooth.

MARGINAL RIDGES

0.5 - 1 mm = 1 (for each interproximal contact between posterior teeth)

     > 1 mm = 2

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

OCCLUSAL RELATIONSHIP

  < 1 mm = satisfactory

1 - 2 mm = 1 (for each maxillary tooth from

  > 2 mm = 2    the canines to the 2nd molars)

  

BUCCOLINGUAL INCLINATION

0  -   1 mm = satisfactory

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

     > 2 mm = 2

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

INTERPROXIMAL CONTACTS

0.6 - 1 mm = 1 (for each interproximal contact)

     > 1 mm = 2         

OVERJET

Anterior teeth must be contacting.

   0 mm = satisfactory

≤ 1 mm = 1 (for each maxillary tooth)

> 1 mm = 2

Transverse posterior teeth:
Mandibular buccal cusps are measured to the central fossa of the maxillary teeth.

ROOT ANGULATION

Parallel           = 0

Not parallel     = 1

Root contacting  

  adjacent root  = 2  (for each occurrence)

**Do not score the maxillary and mandibular canines.  

NOTE:  Gauge Width is  0.5  mm;  Gauge  Height is  1  mm

Third molars are not scored unless they substitute for the second molars.

No tooth is scored more than two points per individual parameter.
