Vertical distance errors (mm) for the different surgical guide methods
| 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 |
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
