Tanaka Johnston Mixed Dentition Analysis

Input The following m-d tooth widths (mm):

Tooth #07: Tooth #08: Tooth #09: Tooth #10:
Tooth #23: Tooth #24: Tooth #25: Tooth #26:

Input The following "Space Available" as measured from dental casts (mm):

Space Available Upper Rt: Space Available Upper Lt:
Space Available Lower Rt: Space Available Lower Lt:
Space Available UR = mm
Space Available UL = mm
Space Available LR = mm
Space Available LL = mm

Tooth #07 = mm
Tooth #08 = mm
Tooth #09 = mm
Tooth #10 = mm

Tooth #23 = mm
Tooth #24 = mm
Tooth #25 = mm
Tooth #26 = mm

Space Required Maxillary Right = (Lower Incisors total width/2) + 11
Space Required Maxillary Left = (Lower Incisors total width/2) + 11
Space Required Mandibular Right = (Lower Incisors total width/2) + 10.5
Space Required Mandibular Right = (Lower Incisors total width/2) + 10.5

Maxillary Rt Space Required = 11mm
Maxillary Lt Space Required = 11mm
Mandibular Rt Space Required = 10.5mm
Mandibular Lt Space Required = 10.5mm

Maxillary Rt Space Excess/Deficiency = -11mm
Maxillary Lt Space Excess/Deficiency = -11mm

Total Maxillary Space or Deficiency = -22mm

Mandibular Rt Space Excess/Deficiency = -10.5mm
Mandibular Lt Space Excess/Deficiency = -10.5mm

Total Mandibular Space or Deficiency = -21mm
