Virtual Surgical Planning (VSP) Plates in Orthognathic Surgery
Overview
Virtual Surgical Planning (VSP) plates are patient specific, pre bent titanium fixation plates designed using advanced 3D imaging and computer aided design/manufacturing (CAD/CAM) technologies. Virtual Surgical Planning plates have revolutionized orthognathic surgery by merging advanced imaging, digital simulation, and precision manufacturing. By incorporating digital planning into maxillofacial procedures, surgeons can achieve greater accuracy, efficiency, and predictability compared to traditional techniques.
How VSP Plates Work
Virtual Planning
The craniofacial structure of the patient is rendered in 3D high definition image and a model is generated over it virtually. Using specialized software, the surgeon can simulate desired jaw movements, evaluate the skeletal discrepancies, and predict both the functional and esthetic results
Custom Plate Design
After the surgical plan is determined, a custom fit plate is designed and constructed using CAD/CAM technology, replicating the patient’s anatomy and the planned skeletal repositioning.
Patient Specific Surgical Guides
In addition to plates, cutting and drilling guides are produced based on the digital plan. These guides help surgeons perform osteotomies and place fixation plates with exceptional precision.
Precise Fixation
During the surgery, the patient specific plate is placed and fixed to retain the segments of the jaw in their predetermined position exactly. This results in predictable outcomes and achieves surgical accuracy.
How VSP Plates Work
Enhanced Accuracy and Precision
VSP allows for accurate transfer of the virtual plan to the operating room leading to accurate skeletal repositioning.
Reduced Surgical Time
As plates are pre-bent, and guides are customised, intra-operative modification is kept to a minimum, thus decreasing both the complexity of procedure and surgeon fatigue.
Improved Functional and Aesthetic Outcomes
More precise adjustability of jaw position results in improved bite relationship, facial balance and long-term stability of the effects.
Comprehensive Preoperative Planning
They allow surgeons to rehearse different treatment options, anticipate potential complications, and improve the surgical outcome prior to the procedure.

FAQs
What are VSP plates and how are they used in orthognathic surgery?
VSP plates are patient-specific fixation plates designed using virtual surgical planning to transfer the planned jaw movements accurately from the digital plan to the operating room.
How do VSP plates improve surgical accuracy?
VSP plates are designed directly from CT-based surgical simulations, ensuring precise execution of planned osteotomies and final jaw positioning without intraoperative guesswork.
Do VSP plates reduce operating time?
Yes. By eliminating manual bending, repeated measurements, and intraoperative adjustments, VSP plates help significantly reduce operative time and improve surgical workflow efficiency.
Are VSP plates compatible with common orthognathic techniques?
Yes. VSP plates are designed to support Le Fort I, BSSO, and genioplasty procedures, and can be adapted to both single-jaw and bimaxillary surgeries.
How do VSP plates affect intraoperative predictability?
VSP plates provide guided positioning and stable fixation, allowing surgeons to reproduce the virtual plan accurately and minimize intraoperative variability.
Can VSP plates reduce dependence on intermediate splints?
Yes. In many cases, VSP plates can reduce or eliminate the need for intermediate splints, simplifying surgical steps while maintaining positional accuracy.
How does virtual planning benefit post-operative outcomes?
Accurate transfer of the surgical plan leads to improved skeletal symmetry, occlusal stability, and predictable aesthetic outcomes, contributing to higher patient satisfaction.
