Virtual resection planning and fibula based mandibular reconstruction, from defect geometry to segment position, guide design, and final contour restoration.
How to acquire the CT/CBCT, dental and fibula donor imaging we need for accurate resection and reconstruction planning — our requirements from your side, on one printable sheet.
When a tumour is removed from the jaw, the missing bone is rebuilt, most often using a section of the patient's own fibula (the slender bone of the lower leg). We plan the removal and the rebuild together in 3D before the operation.
The native jaw defines the gap to fill, the fibula provides the bone, and the new contour is checked against the bite, facial symmetry, and jawline before anything is made, so the surgical concept reaches the operating room with clear references.
The reconstruction is planned from both sides of the problem. The mandibular defect defines the target shape, while the fibula is divided into segments that can reproduce the lower border, angle, and ramus contour.
The fibula is virtually osteotomized into planned segments and arranged to match the mandibular defect. Segment length, angulation, and final position are controlled in relation to the residual mandible.
The design should make the reconstruction understandable before surgery: where to cut, how to rotate each segment, and how the final mandibular contour should be restored.
A reconstruction plan becomes useful when each digital decision is translated into a guide, a surface, a screw corridor, or a sequence that can be repeated during surgery.
The mandibular defect and residual bone are evaluated so that resection planes and reconstruction endpoints are clear.
The fibula is divided into planned segments that reproduce the desired mandibular curvature.
Separate cutting guides are made for the fibula and the mandible, plus a model of the planned jaw to check the final shape.
Fixation is coordinated with segment position, screw access, and the final reconstructed contour.
The final reconstruction is not only a bone transfer. It is a controlled geometric transfer from the virtual plan to the patient, with the occlusal plane, inferior border, ramus height, and facial symmetry kept in view.
The fibula is divided into pieces that recreate the natural curve of the jaw.
Cutting guides seat on stable bone, so each cut lands in the planned position.
The rebuilt lower border and jaw angle are checked for symmetry.
Resection of the mandible and reconstruction with a fibula free flap in three segments, planned by mirroring the healthy side.
Two cutting guides for the jaw, one for the fibula, and four printed models: one to test the fit, one to place the bone pieces, one to bend the plate before surgery, and one of the jaw as it was.
