Purpose: To find a solution for individualized contour reconstruction of severe mandibular defect based on craniomaxillofacial correlationship.
Materials and Methods: Total 10 adults with normal occlusion were included in this study. After cephalometric analysis, accuracy of regression equations of mandibular contour variables from our previous series studies on mandibular contour correlation was testified by statistical analysis. Meanwhile, the data of mandibular contour variables and lateral inferior arc curve of mandible were supplied for one patient with severe mandibular defect for individualized reconstruction.
Results: No statistical difference (p>0.05) was presented between the values of mandibular contour variables from two different methods (actual measurements and mathematical calculations). Moreover, aesthetic profile was obtained postoperatively in this clinical case.
Conclusion: Analysis of mandibular contour correlation could provide very important data for individualized reconstruction of severe mandibular defect.

Clinical Significance: Correlation study of mandibular contour versus three dimentional cranio-maxillofacial structures provided a beneficial exploration for individualized reconstruction of severe mandibular defect with loss of primary position.
