Conditions

pathologic lesion of mandibular body. Benign neoplasm of bone and articular cartilage

Interventions

Intervention 1: intervention1: In the group using three-dimensional printer, after acquiring a CT scan of axial, coronal and three-dimensional reconstruction views, prototype three-dimensional models

Finally, after placement and fixation of reconstruction plates, surgical site will be sutured to end the surgery. During surgery, the amount of blood loss and duration of the operation is measured in
