CT-scan segmentation & 3D reconstruction

1. CT-scan segmentation & 3D reconstruction

Based on the CT-scan, we reconstructed the patient's skull in 3D.

Implant design

2. Implant design

Using the 3D reconstruction, we designed a 3D implant design fitting the cranial defect, taking into account the surgeon's feedback.

Custom mold

3. Custom mold

The custom mold was manufactured by 3D printing, delivered with a biocompatible model of the patient's skull and an implant trial. Everything was sterilized in-hospital.

Molding

4. Molding

At the early stage of the surgery, bone cement (PMMA) was introduced in the mold. Once the dissection was performed, the mold was opened to obtain the implant.

Adaptation

5. Adaptation

The implant was validated on the model of the patient's skull and on the patient's head. Its contours were slightly adapted by milling to obtain a perfect fit. The surgeon also decided to make holes in the implant before implantation.

Fixation

6. Fixation

The implant was fixed using square-shaped miniplates and the result was exactly as planned.
