Craniomaxillofacial reconstructive surgery is primarily targeting to restore primary functions and the same time to preserve craniofacial anatomical features like symmetry and harmony.
The craniomaxillofacial reconstructive surgery was one of the first areas where the 3D printed implants have been used in practice. Modeling has been used in craniofacial reconstruction of traumatic injuries, congenital disorders, orthognathic surgery, tumor removal, and implantology. 3D printing greatly improves and enables preoperative planning, reduce operative time, and significantly improve the biofunctional and the aesthetic outcome.

Computer-aided design (CAD) used to generate 3D proposed implant has a major impact on success of cranio-maxillofacial (CMF) surgery, significantly improving efficiency, accuracy, creativity, and reproducibility. We care about each patient and provide end-to-end solution. Our highly skilled specialists will analyze 3D image data, design a 3D model of the implant and propose this model to doctors. After satisfying all patient-specific implants’ requirements and getting the approval from doctors we produce the final implant using advanced 3D printing or CNC machining technologies.

Implants for craniomaxillofacial (CMF) surgery: The full process

The objective of this step is to obtain patient-specific models and implants from computed tomography (CT) scan data. To proceed, firstly the CT scan data of the patients have been obtained in digital imaging and communication in medicine (DICOM) file format. Next, the DICOM files have been converted into computer-aided design models and saved in stereolithography (STL) format. Finally, the STL files have been cleaned and corrected and loaded to design the customized implants. Upon request, finite element analysis has been performed to check the strength of designed implant.

2. Design

Design based on analysis of 3D imaging data. These image-based segmentation methods can be applied on radiological image data from computed tomography (CT), positron emission tomography (PET/CT) or magnet resonance imaging (MRI) scans.

3. Rapid prototyping

The main goal of rapid-prototyping is to have physical samples. This helps to examine and estimate how well the implants fit with damaged/deformed areas. Rapid prototyping is done by stereolithography. Usually, both the implant and the damaged / deformed area is being printed.
  1. In the first step the implant is fabricated by plastic. This plastic model is assembled with stereolithigraphic model of damaged area. This helps to understand whether the implant is fitting well or additional modification are required for subsequent intraoperative use.
  2. If the plastic model of the implant fits well to the receptive bone model then, a titanium implant is printed

CT or MRI scanning of the patient to get damaged or deformed bone(s).

Based on CT data the damaged bone and the part where the implant should be placed are being modeled.

The implant and the bone is being printed (plastic). The physical samples is provided to doctor. After feedback and correction the implant is being printed

The doctor has time for pre-operation training and optimization of the surgery process. Then surgery is being performed

4. Maxillofacial surgery

This patient is a heavy drug user. Due to this addiction the bone had badly deteriorated and partially degenerated. He had double vision because of dislocation of one eye. We suggested several models of implant. However, considering the health condition, quality of bone the doctors chose the version of implant shown below. The surgery was successful. The main task of recovering the vision as well as esthetics of the face was accomplished.
