# Wafers Orthopathic Surgery with Customized Osteosynthesis and Surgical Guides: A Prospective Study
## 3 Results
### Signed Values  
The accuracy analysis revealed an overall deviation of \(-\)0.08 mm (95%CI: \(-\)0.16-0.01). Mandibular landmarks exhibited greater deviation compared to those associated with the maxilla (MD: 0.19 mm; 95%CI: 0.01-0.36; \(p=0.037\)) (Figure 5). As in the previous analysis, the magnitude of change (deviation versus 2 mm reference value) remained <2 mm for all assessed landmarks (\(p<0.001\); one-sample \(t\)-test). \begin{table}

Table 2: Accuracy values, expressed as mean and SD, stratified by arch and axis. Figure 5: Box plots illustrating signed deviations between the preoperative plan and the final result, stratified by location. * Statistically significant (\(p<0.001\)). Examining the deviations along the three axes, the mean deviation was \(-0.08\) mm (SD = 1.02) on the X-axis, 0.14 mm (SD = 1.82) on the Y-axis, and \(-0.27\) mm (SD = 1.16) on the Z-axis (F [2, 1053] = 7.82, \(p\) < 0.001). Notably, statistically significant differences were identified between the Z and Y axis (MD: \(-0.41\) mm; 95%CI: \(-0.65\) to \(-0.17\); \(p\) < 0.001) (Figure 6).
