Abstract Objectives The aim of the current study was to evaluate potential differences in accuracy mandibular reconstruction and long-term stability, with respect different reconstructive procedures. Methods In total, 42 patients who had undergone primary segmental resection immediate alloplastic reconstruction, either manually pre-bent or patient-specific plates (PSMRP), were included this study. Mandibular dimensions, terms six clinically relevant distances (capitulum [most lateral points], capitulum medial incisura caudal foramina, coronoid process cranial dorsal tip mandible closest gonion point) determined from tomographic images, compared prior to, after surgery. Results Dimensional alterations significantly more often found when conventionally bent titanium used. These occurred area ( p = 0.014). Plate fractures 0.022) within group than PSMRP (17%/0%). Conclusion results suggest that use may prevent rotation proximal segment, thus avoiding functional impairment. addition, potentially enhance stability reconstructions.
