Innovative 3d modeling in medicine

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…

MaterialiseThe design of a custom prosthesis

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

Curve

Result

2. Design for a large cranial defect

3. Design for missing orbit

Example

•The mirrored skull positioned at the desired spot
