The use of modified 3D-printed reconstruction plates in mandible segmental defect rehabilitation: a case report

The preliminary safety and accuracy of a modified 3D-printed reconstruction plate (3DPRP) for mandible segmental defects were evaluated. Two patients with mandible segmental defects who underwent reconstruction using 3DPRPs were included in the study. No dead space, wound healing failures or fractures were observed. The mean deviations for the two patients were 0.59 and 0.57 mm and the condyle changes were 1.01 and 0.88 mm, respectively. The deviations in the distances between both sides of the mandibles (D1–6) ranged from 0.67 to 1.16 mm and from 0.43 to 0.61 mm for the two patients. The preliminary results show that the modified 3DPRPs are safe and accurate.
