SurgiCase is Materialise' new software platform for surgery planning and simulation and comes in two flavors. SurgiCase CMF is intended for the cranio-maxillofacial surgeon, while SurgiCase Orthopaedics is designed for planning orthopaedic surgeries.

Learn more about Materialise' new surgery planning software for cranio-maxillofacial interventions, SurgiCase CMF. This session includes case study lectures and hands-on training sessions for SurgiCase CMF.

3D applications in modern high-tech surgery

Modern image-guided techniques are the basis for diagnostics, therapy and documentation. These technologies enable us to produce an individual anatomical picture of the patient´s specific situation. They give us the possibility to perform accurate planning and transfer the to the operation theatre.
Due to the close proximity of highly vulnerable anatomical structures and on the other hand due to the complex morphology of the region, surgical interventions in the cranio-maxillo-facial area and even their planning make high demands on the spatial sense of the surgeon.
Three- dimensional visualisation- techniques are very suitable for the display of complex structures of the facial skeleton and of the skull base.
Apart from Visualisation, 3D-operationplanning is one of the main applications of the currently available software systems. Accurate planning is a precondition for a successful treatment in reconstructive and cranio-facial surgery.
Bring the planning data to the operation theatre with a high degree of accuracy is the logic consequence of improved planning systems. In the future the navigations systems will on one hand guide the surgeon in delicate clinical situations as well as they will become systems for quality control to check whether the planning was correctly transferred into the OR.

SurgiCase CMF, the clinical aspects. Looking to the future with CMF

During a modern information epoch speed and accuracy the decision of a task is very important. Medicine is not an exception. Where possibility of planning of treatment results always was compliments. And accuracy and speed became signs of a high level of professionalism. Thanks to new software SurgiCase CMF from Materialise maxillofacial surgery has received new push in field exact, fast and reliable preoperative planning.
By this technology virtual three-dimensional (3D) models of the facial soft tissue and bony structures generated from CT-scans without any geometry distortion are used to perform relocation planning and soft tissue prediction.
Using experience LIRA Medical Centre in the report the basic planning directions of maxillofacial area surgery are surveyed, such as planning of distraction, orthognathic surgery and reconstruction planning by means of SurgiCase CMF. Is shown orbital and maxillary reconstruction planning, LeFort II osteotomy and BSSO planning and unilateral mandibular ramus distraction. Results are induced. Possibility of work with different elements of the program on an example of live clinical cases is shown. There are allocated advantages of 3D surgery planning in several clinical conditions

The SurgiCase CMF software: a new way of planning in orthognathic surgery

There are many techniques available for orthognathic treatment planning, however maxillofacial malformations still present challenges in analysis and correction although modern technology.
Purpose: The aim of this study is to present a virtual-reality software for surgeons to perform virtual orthognathic surgical planning with 3D hard- and soft-tissue prediction. The study evaluates the role of a new computer imaging software (SurgiCase CMF software - Materialise) to plan the outcome of soft tissues after bimaxillary orthognathic surgery.
Materials and Methods: The study sample consisted of 10 adults pts who had undergone orthognathic surgery that included Le Fort I and Bilateral Sagittal Split Osteotomy procedures and optional genioplasty to correct malformations. All the patients had cephalometric radiographs and CT scan. The surgical planning system consists of four stages: computed tomography data reconstruction, three-dimensional facial hard- and soft-tissue model generation, different virtual surgical plannings and simulations, preoperative predictions of soft-tissue changements. The surgical planning and simulation are based on a 3D CT reconstructed bone model; the soft-tissue prediction is based on physical algorithm.
Results: The software rapidly generates many simulations and soft tissue predictions according the clinical options; so it is possible to plan the surgery choosing between different aesthetic results. Preoperative plannings were prepared working with the orthodontist to avoid functional problems.
Conclusions: SurgiCase CMF software is able to provide a prediction of postoperative appearance with realistic quality. The simulation can be visualized from any viewing point using a personal-computer-based system, so this solution can be adopted for hospital daily use. The accuracy of the software in soft tissue will be discussed.

New material and new method for reshaping lost tissue in situ

Purpose: After the loss of soft tissue in the surface of the body generally the defect is surgiacally reconstructed with a flap. But this is not always possible. Another option for the rehabilitation is the reconstruction with prostheses as a substitute in the colour and shape of the lost of the body. However we developed a new mineralic substance and a method for reshaping the contours of lost bodyparts in situ.
Methods and Materials: The mineralic substance is applicated as a powder in the wound and then the wound is closed by bandage for three or four days. After these days the wound is cleaned again and after debridement and the application of a new portion of the wound healing substance the wound is bandaged again. We do not use any groth factors or proteins. Our material is pure mineralic substance. It is not a drug but it is a medical device.
Results: After three to six weeks the cavity of the wound is filled with ingrown juvenile tissue and perfectly covered with skin. Thus we could cure diabetic feet and a necrotic finger. After four pilot cases in which we could cure necrotic to nicely vascularised juvenile soft tissue we developed in a further step shapes and moulds of bodyparts and facial parts which are modified facial- and breast prostheses of our standard prosthetics programm. These standard shapes for bodyparts have a thin layer of our wound healing substance on their back side.
Conclusion:The goal is to let the soft tissue grow along the backside of the preshaped template. While the soft tissue in the depth of the wound is feeded with our mineralic wound healing substance the bodyshape template is the limiting surface cover for the ingrowing soft tissue which creeps along the back side of the template. The template is used as a bandage and it is removed every few days, then it is replaced after the debridement of the wound and the application of the wound healing substance. The advantage of the new material and method is that we can avoid scars and we see a new use for facial and breast templates for the remodelling of soft tissue in situ. Thus we reshape lost parts of the body by remodelling the tissue with the help of a mineralic powder which lets soft tissue grow into the preshaped templates which covers the defect as a wound healing plate.

Sponsor Lecture: Ultrafast 3D imaging for healthcare

This talk will cover the topic of 3D surface acquisition and application where ultra-fast and high precision representations of living subjects are required. The advantages and deployment of a technique known as Active Stereo Photogrammetry will be covered in the context of the systems developed by 3dMD. Examples will be shown of applications for analyzing and comparing 3D surface data sets of the human form. The session will close with a review of the application of new techniques for Dynamic 3D Surface capture (sometimes described as 4D) where a sequence of accurate surfaces can be captured for several minutes.

3D planning for orthognatic surgey - current possibilities

3D planning for orthognatic surgey - current possibilities
Accurate pre-operative planning of corrective surgery of deformities in the facial skeleton is essential for successful surgical treatment. Particularly in highly elective surgery such as orthognatic surgery, this kind of operationsplanning gets more and more important. Patients consent and quality control will become more and more important in this field.
Virtual 3D- models of the facial soft tissue and the underlying bony structures generated from CT- Scans are used to perform relocation planning and soft tissue prediction with the Surgicase planning software.
