Overview

3D Systems' product focused on routine orthognathic surgery is VSP Orthognathics. Utilizing medical imaging data from a CT/CBCT, plus occlusal anatomy data, a complete planning service eliminates the need for traditional model surgery. An interactive web meeting between the surgeon and an engineer is performed to allow for simulation of the procedure, including surgically accurate placement of osteotomies and bony movements. The end result is an intermediate and final splint providing the clinical transfer of the digital plan into surgery. In addition to the splints, a case report detailing the osteotomies, movements and cephalometric movements is provided. Additional patient-specific surgical guides can also be produced as required.

Benefits

At the heart of the VSP® Orthognathics product is the transition away from traditional model surgery to a more accurate, anatomically based surgical simulation method. By combining medical imaging (CT/CBCT), accurate planning of osteotomies and movements, and precise surgical splints, the system removes hassle by streamlining cases and providing excellent clinical results. Surgery may be made more predictable and efficient through visualization of the anatomy through the planning process and by identifying where bony overlaps and gaps exist, all before surgery.

Technology

More than 10 years of research and development have culminated in a streamlined product offering for orthognathic surgical planning. Keys of 3D Systems' technology include the ability to accurately integrate occlusal data from high-resolution scans of the stone models and their ability to fabricate guides, splints and other tools as needed for your case using 3D printing technologies. 

Case Flow

  • vsp orthognathics preop photo

    Patient presents with Class III malocclusion. Surgical planning to include a mandibular setback and LeFort I advancement.

  • vsp orthognathics scans occlusal surface

    High resolution scans of the occlusal surfaces are integrated with the CT/CBCT data.

  • vsp orthognathics accurate osteotomy simulation

    Accurate osteotomy simulation tailored to clinical requirements.

  • vsp orthognathics real-time 3d-bony movement ceph analysis

    Real time 3D bony movement and cephalometric analysis.

  • vsp orthognathics post op photo

    Post-operative surgical result shows balanced facial proportions.

Splint and Guide Design

As the direct link to a case, the splints are highly important outputs of the system. Splints are designed with a number of customizable features, such as minimizing/maximizing occlusal overlap, palatal strutting, sandwich splints (for segmental LeFort I cases) and more. Final surgical splints are produced in a clear material approved for up to 30 days of intraoral use.
