Craniomaxillofacial Surgical Planning
This complete planning service eliminates the need for traditional model surgery. The first step is an interactive web meeting between the surgeon and an engineer where they simulate the procedure, including surgically accurate placement of osteotomies and bony movements. The result is an intermediate and final splint providing the clinical transfer of the digital plan into surgery. Splints are designed with several customizable features, such as minimizing/maximizing occlusal overlap, palatal strutting, sandwich splints, and more. Final surgical splints are produced in a clear material approved for up to 30 days of intraoral use. Additional patient-specific surgical guides can also be produced as required.
This surgical planning solution is intended for head and neck reconstruction. The most widely used application is for mandibular or maxillary reconstruction using the fibula free flap and other vascularized grafts. It can also be used for reconstruction techniques for trauma, congenital defects or tumors of the facial skeleton. Surgeons report that use of the VSP Reconstruction solution enables them to perform these surgeries with more confidence and a three-dimensional perspective as compared to cases without pre-surgical planning. Dozens of peer reviewed journal articles substantiate the use of the VSP Reconstruction models, guides, and templates to reduce surgical time and create more accurate reconstructions.
This solution applies proven and FDA-cleared virtual surgical planning techniques to craniofacial cases, especially procedures related to craniosynostosis and cases that require cranial vault distraction. Building on the success of the renowned VSP surgical planning solutions, VSP Cranial delivers improved surgical outcomes to surgeons by providing accurate pre-surgical visualization of cuts and movements, real-time comparison to age-matched normative anatomical contour, and personalized marking and positioning guides for realization of a digital plan.
These surgical planning solutions for distraction osteogenesis include designing placement of osteotomies, planning of distractor vectors and creation of templates for guidance of device placement, device bending and osteotomy placement. The patient’s 3D anatomy is reviewed during the planning session, and underlying teeth roots and nerves are visualized for proper distractor placement. Each case is customized to the actual distractor file to be used during surgery. Some uses of VSP Distraction include osteotomy placement, identifying a distraction vector plan, creation of templates to guide device placement, and facilitation of pre-operative hardware set up.
This solution allows the surgeon to digitally reduce the fractured bony segments prior to surgery. The digitally reduced plan is transferred to the operating room through a series of models, guides, templates, or digital images. Since these are typically time-sensitive cases, 3D Systems makes quick service a priority. Deliverables for VSP Trauma cases include patient-specific osteotomy and positioning guides, occlusal-based positioning splints, and digitally reduced, perfected or mirrored anatomic models. Modified DICOM can be produced based on the surgical plan for use in intraoperative stereotactic navigation systems.
Jaw in a Day
Jaw in a Day® enables immediate placement of a provisional dental prosthesis during a single-stage free tissue transfer jaw reconstruction surgery. The surgical planning, along with guide and prosthesis designs, is completed using state-of-the-art CAD/CAM technology, allowing the patient to emerge after a single surgery with a full jaw reconstruction, including dental rehabilitation.
