The Cranioplasty mould is a patient-specific mould that is used intraoperatively to produce a PMMA (polymethyl methacrylate) cranioplasty prosthesis.
Once the CT scan has been converted to a virtual 3D model, the patient-specific implant is designed on the patient's defect. The affected anatomy and the cranioplasty prosthesis is then manufactured with the use of 3D printing. A two-part platinum based silicone mould is made for the prosthesis. The moulds are delivered to the clinical team non-sterile. (click here for sterilisation parameters) The mould is autoclaved and used in theatre to recreate the prosthesis with PMMA.

Advantages:
- Perfect fit to the patient's defect with excellent cosmetic results
- The most cost-effective cranioplasty solution
- Reduces surgery time
- Very simple to use
- PMMA has the advantage of being inert, radiolucent and non-magnetic
- Decreases potential complications associated with the use of PMMA
- Fast turnaround time (5-10 working days)
