Example
The length of the x-ray calibrator on the radiograph (XRC) is
55 mm (magnification 1.10).
The maximum condyle width on the radiograph (MCW)
amounts to 91 mm.
Preoperative Planning
RCW=

55
⳯
91 = 83 mm
The real condyle width (RCW) is therefore 83 mm.
The screw lengths are therefore:
Screw hole Screw length (mm)
A 75
B 40
C 55
D 65
E 75
F 75
G 65
Important:
The proper placement of the plate on the
condyle is essential to ensure the correct screw length.
