Computer-Assisted Mandibular Reconstruction using a Patient-Specific Reconstruction Plate
Fabricated with Computer-Aided Design and Manufacturing Techniques.
The mandible was reconstructed with titanium reconstruction plate
of approximately 10-cm length (extending from right body region to left angle of the mandible) after contouring the plate over the outer surface of the resected mandible.
An open reduction and internal fixation (ORIF) was planned for her comminuted mandible fracture by using a prebent reconstruction plate
through the existing wound.
The slid bone is fixed by two screws (1) and a small plate (2), and (3) indicates the reconstruction plate
. Cross-sectional computed tomographic image (b).
Following tumor extirpation (Figure 4(d)), a 2.0 mm reconstruction plate
was secured to the mandible, and an autogenous anterior iliac crest bone graft was used to reconstruct the mandibular defect (Figure 4(e)).
The mechanical advantages of a parallel plate configuration have been demonstrated for conventional reconstruction plate
design (29), as well as for locking plate construct (23).
However earlier attempt should be made to stabilize the mandible with either bone graft or reconstruction plate
in patients with respiratory or feeding problems.
[sup] analyzed the biomechanical characteristics involved in TEN fixation and reconstruction plate
fixation for mid-shaft clavicular fractures, presented by biomechanical finite element analysis, showed that reconstruction plates
and ESIN yielded similar functional results, time to union, level of postoperative pain, and patient satisfaction rates.
Next, a reconstruction plate
was bent to produce a hook-like plate to hold the fractured bone to the inner wall, and the plate was fixed on the ilium (Figure-D).
A large dome fragment along with a transverse fracture was stabilized with a pelvic reconstruction plate
. A greater trochanteric osteotomy was performed at the time of the surgery to aid in exposure.
The two mandible segments and the bone flap were plated using a reconstruction plate
