From: Precision of fibula positioning guide in mandibular reconstruction with a fibula graft

Measurement point Fibula cutting guide alone (control group) Fibula cutting guide & fibula positioning guide (experimental group) P value
Anterior segment-mesial point 1.8 ± 2.0 −0.2 ± 1.1 0.002*
Anterior segment-distal point −0.1 ± 5.6 0.1 ± 3.6 0.850
Middle segment-mesial point −0.1 ± 6.1 0.1 ± 3.7 0.902
Middle segment-distal point 6.0 ± 12.3 2.8 ± 7.6 0.400
Posterior segment-mesial point 6.6 ± 12.3 3.6 ± 7.6 0.432
Posterior segment-distal point 8.5 ± 13.8 5.3 ± 8.7 0.460
Condyle lateral point 7.8 ± 12.9 3.5 ± 7.7 0.287
  1. Note: Values represent the mean ± standard deviation. The segment is the fibula segment used to reconstruct the mandible, and the position refers to its placement in the mandible. The condyle is on the left mandible, where it is articulates with the skull. Negative values indicate that the position of the point in the model was closer to the FH plane than the corresponding point in the simulation
