3-d 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 (n = 15)	4.3 ± 2.3	3.1 ± 1.5	0.096
Anterior segment-distal point (n = 15)	7.2 ± 3.2	5.7 ± 3.6	0.260
Middle segment-mesial point (n = 15)	7.7 ± 3.5	6.3 ± 3.6	0.290
Middle segment-distal point (n = 15)	16.5 ± 8.1	12.1 ± 7.7	0.147
Posterior segment-mesial point (n = 15)	16.8 ± 7.9	12.0 ± 7.9	0.111
Posterior segment-distal point (n = 15)	18.1 ± 9.8	14.5 ± 8.8	0.304
Condyle lateral point (n = 15)	19.4 ± 8.9	16.2 ± 8.7	0.338
Total (N = 105)	12.8 ± 8.8	10.0 ± 7.9	0.015*

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
