is a unique system of manufacturing moulding forms for custom-made implants,
especially for reconstruction of cranial defects. A final implant is prepared
and shaped using the form just before the surgery. Any cement made with
resins as the basic ingredients is suitable material for the implant. The form
is composed of two parts (top one and bottom one) made of high molecular weight
polyethyle (HMW-PE), while specific shape of the form is planned according
to CT examination of the patient.
We recommend the resin Cranioplastic®, product of the Codman
Johnson & Johnson
company, for the use with the CranioForm system.
Typical Procedure
Standard CT examination.
Computer model of a patient skull.
3D defect rekonstruction.
Moulding form manufacturing.
Diagnostic CT examination
Standard noninvasive diagnostic treatment.
Optimal slice thickness ~1mm.
Zero tilt ("gantry").
Bone reconstruction window.
Beware of metal objects in the area of examination to prevent
image degradation and unwanted artefacts.
Export CT data to the DICOM format.
Computer model of a patient skull
Tissue segmentation.
Creation of a 3D surface model.
Accuracy ~ slice thickness.
3D defect rekonstruction
Geometrical modeling of the cranial defect, and shaping of the supplement.
Recovery of the skull symmetry.
Altenatively an atlas of anatomical structures
and models can be used.
Moulding form manufacturing
Based on the 3D defect reconstruction, moulding form is designed and manufactured.
Material: high molecular weight polyethylene (HMW-PE).
Accuracy ~ 0.1mm
Surgery
The final implant is shaped just before the surgery using the prepared form.
Any certified plastic material is allowed (Cranioplastic, Palacos, etc.).
Time of the surgery can be significantly reduced.
The implant suits to concrete patient and treatment.
Terms
