The aim of this observational, longitudinal and retrospective study was to evaluate the fidelity of virtual surgical planning (VSP) performed on Dolphin Imaging & Management Solutions® 11.95 software on hard tissues, using the tools of the open-source software OrtogOnBlender - Blender3D. For this, linear, angular and 7-point anatomical measurements of the skeletal profile were used, and the discrepancies between the VSP and the result after bimaxillary orthognathic surgery were calculated. Pre- and postoperative cone beam CT (CBCT) scans of 43 consecutive patients with class II and III skeletal deformities were evaluated and the results of the VSP were compared to the 1-month postoperative results. All overlapping points presented values within the range considered clinically irrelevant (< 2 mm and  0.05). The comparison of anatomical points showed lower values (≤ 2.11 mm) in point A of class II. For hard tissues, the comparison between VSP and 1-month postoperative tomography demonstrated the faithful results of virtual planning using this software.
