... it seems that she got left subcondylar fracture as a complication of the previous surgery and this led to mandibular defect and facial asymmetry due to malunion of two fractured segments. That is why she presented to our Department of Oral and Maxillofacial Surgery at Seoul National University Dental Hospital complaining from facial asymmetry ( Fig. 2A, E). Upon clinical examination and radiographic analysis, we found that her mandible deviated to the left side and the maxilla was canted down on the right side. Using 3D-CT superimposition a ramus deficiency and mandibular body border excess were detected in the left side of her mandible (Fig. 2C). Then CAD-CAM titanium reconstruction ...

... technology as this helps to achieve a precise diagnosis and made almost perfectly designed prosthesis and we have an example of accurate defect amount detection in the mandibular ramus of the 2nd case, amount of mandibular border excess ground with a guide of designed surgical stent and symmetrically precise restoration of the deficient ramus (Fig. 2). In addition to that, the 3rd case can show us that intraoperative consumed time is decreased by using customized surgical stents to locate and fix fossa and condyle accurately (Fig. 3). We think that titanium prosthesis is an excellent choice for efficient and durable reconstruction of such large maxillofacial defects. Moreover, ...
