3di Patient Specific Skull Implants



  • 02.1 Produkte
  • Our main products are patient specific implants
    for the brain- and face-skull areas.

    These patient specific implants can, for example, become
    necessity after trauma, tumour surgeries,
    surgery accesses,
    or in case of functional-aesthetical corrections.

    For the fabrication of such implants, the company
    has developed its own procedure.

    This new procedure allows us to create implants
    which are custom-made for
    every patient.

    Modelling, construction and manufacturing are exclusively virtual process. In consideration of the surgical-technical aspects it is therefore possible to create patient specific implants in best time.

Implant Materials

We produce implants consisting of the following materials:

  • BIOVERIT®II

    We use the glass ceramics BIOVERIT®II, which has been developed under the supervision of Prof. Vogel by the department of glass chemistry of the Friedrich-Schiller-University Jena. This material consists of machinable glass ceramics of the SiO2-Al2O3-MgO-Na2O-K2O-F-system. BIOVERIT®II is an non-resorbable glass ceramic, which consists of a crystal phase (approx. 60%) with mainly Phlogopite–crystals, embedded in an alumosilicate glass matrix (approx. 40%).

    Here you can find more Information of our implant material BIOVERIT®II.

  • PEEK

    PEEK was deverlop as non-resorbable high performance thermoplastic for the long-term implantation. Since 2008, 3di GmbH is producing patient specific implants for the cerebral and visceral cranium made of this material. PEEK is intraoperative machinable.

    Here you can find more Information of our implant material PEEK.
  • Titan

    Titanium is a dark grey material, which is highly stable. Due to this stability, it is possible to make the implants very thin. A subsequent machining with OP-tools is very difficult or not possible due to the high strength. Titanium is an implant material which is long-term proven for many body regions.

Procedure

  • 1. Data acquisition
    First of all, the necessary data of the patient is gathered with the imaging procedure like computer tomography and afterwards stored, e.g. in DICOM- format.
  • Ablauf 1.1 mod
  • 2. Data transfer
    The data can be saved to CD-ROM, DVD or USB flash drive and can be sent to us. You are welcome to send data encrypted and quickly with our internet transfer portal which you can find at https://transfer.3di.de.
  • Ablauf 2 mod
  • 3. Data preparation
    The data of the patient is prepared and converted by us; a virtual 3D-patient model is created.
  • Ablauf 3 mod
  • 4. Construction of a 3D-implant model
    On the basis of the virtual 3D-patient model an implant model is constructed. After consultation between you, the treating physician, and our technical designers, you determine the final implant shape. The consultation can take place either via telephone or via E-mail. If necessary we send you also real 3D- model for the implant planning.
  • Ablauf 4 mod
  • 5. Transformation in CNC-data
    After the clearance of the implant shape, the construction data is converted into CNC-data.
  • Ablauf 5 mod
  • 6. Choice of material and manufacturing
    The material is selected, according to medical and technical aspects; only medically certified materials are used, which are compliant to the MPDG (Medizinprodukterecht-Durchführungsgesetz). Afterwards, the computer-assisted manufacturing is carried out in our modern fabrication centre.

FAQ

 

  • Which materials can be used?
    All clinically tested and certified materials can be used (metals, ceramics, plastics etc.). However, we recommend the use of BIOVERIT®II, PEEK and Titanium because these materials offer most advantages.
  • How complex can the implants be? How accurately are they adapted to the defect area?
    Any bone structure of the human head can be recreated. The accuracy amounts to < 0.5 mm. The quality depends on the CT data we receive (age, layer distance).
  • How long do you need for the production of an implant?
    We need approx. 3 work days, but in case of an emergency, we are able to provide it within 48 hrs.
  • How does the data communication between the physician and 3di take place?
    The CT/MRT data can be sent to 3di on CD-ROM or transmitted via secure internet access. Here you can find further information.
  • Which procedures and parameter are advantageous?
    The optimal parameters can be obtained from us. Here you can find further information.
  • How does the payment for the implants occur?
    3di offers to assist you with negotiations with the cost objects as well as with budget agreements with health insurance companies.
