Neurosurgical cases

CASE: Cranioplasty moulds

Based on the patient’s CT medical scan, the mould is designed and manufactured by medical 3D software and 3D printing technique. After being produced, approved and sterilized, the mould is ready for use.
In the OR the surgeon applies bone cement (PMMA) into the mould. After 10-16 minutes the implant is ready to be adopted and fixed into the patient.
The purpose of cranioplasty is to prevent injuries and infection in the brain, to correct cranial deformations and restore the aesthetic of the skull.

Advantages of the implant mould for cranioplasty

  • 3D printing technique is accurate and fast (designed and manufactured within 24 hours)
  • The implant is manufactured and adaptable in the OR
  • Designing of the mould is easy and fast
  • It can be designed and produced with feedback from and according to desire of the surgeon
  • Cost effectiveness
  • It saves time in the OR
  • The Implant is ergonomically accurate and precise fit for patient’s anatomy

How does it work 

  • After the CT images, which must be newer than 60 days, are approved the design of the implant and construction of the mould is done with the 3D design software Segment 3D. This is done in consideration of the surgeon’s feedback and desires.
  • Anatomical mould is produced by means of 3D-printing equipment and biocompatible materials, as fast as within 24 hours.
  • After washing, cleaning and inspection, the mould and implant trial model are sent for final sterilization.
  • In the OR, the surgeon uses a 3D printed copy of the implant for placement and fitting verification.
  • If the surgical intervention is new the surgeon uses a patient-specific surgical guide for presurgical planning and navigation.
  • The making of the implant is easily done by placing bone cement (PMMA) into the mould sections. After 10-15 min the implant is ready for final adaption and approval by the surgeon.
  • The implant can be fixed into the patient by any fixation system available.
