Scope of the presentation…
• About Materialise• Technical introduction:- Starting from CT/MRI images, Mimics software can
make an accurate 3D reconstruction of the anatomical structures and export STL files.
- 3-matic software is capable of designing implants based on these 3D reconstructions, on STL level (no reverse engineering necessary)
- The final implants can be produced by Direct Metal Laser Sintering

What is Mimics?
• Mimics allows you to: • import scanned images • select structures in the images
• These structures can then be used for different applications…

Classification of cranial prosthesis
1. ‘Simple’ Cranial defect
2. Large cranial defect
3. Missing orbit

1. Design for a simple cranial defect

Strategy - Example
• Draw a curve around the defect• Make sure you draw it far
enough from the border since we will make a tangential hole filling
• Use the “Create Cranioplasty Prosthesis” function
