Anteroposterior 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	−2.0 ± 3.1	−1.8 ± 1.9	0.854
Anterior segment-distal point	−0.4 ± 5.0	1.0 ± 5.3	0.439
Middle segment-mesial point	−0.6 ± 5.2	0.6 ± 5.8	0.543
Middle segment-distal point	1.2 ± 10.4	4.3 ± 10.3	0.416
Posterior segment-mesial point	0.9 ± 10.6	4.1 ± 10.4	0.408
Posterior segment-distal point	−1.0 ± 11.6	3.0 ± 12.1	0.359
Condyle lateral point	3.2 ± 13.2	4.8 ± 13.9	0.738

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 coronal plane than the corresponding point in the simulation
