Table 2 Comparison of surgical outcomes with and without 3D models. Welch’s t test was used to test the difference between the mean values of amount of bleeding and the operating time
From: Utilization of desktop 3D printer-fabricated “Cost-Effective” 3D models in orthognathic surgery
With 3D models | Without 3D models | p value | |
|---|---|---|---|
Number of cases | 25 | 20 | |
Mean amount of bleeding | 252.2 ± 97.7 g | 331.2 ± 85.9 g | 0.0971 |
Mean operating time | 226 ± 18 min | 260 ± 36 min | 0.0255 |
