How is Virtual Surgical Planning different from Conventional Surgery Planning?

The conventional surgery planning process involves cephalometric radiographs with tracings, dental impressions, and articulator-mounted models.

This technique has inaccuracies amplified during the algorithmic process, whereas, in Virtual Surgical planning, the patient’s DICOM file allows generating OPG and lateral-cephalogram and provides the Orthodontist and the Surgeon with the pre-surgical COGS and several other analyses.

In the conventional method, we also must put efforts in taking alginate/rubber-based impressions, mounting of stone models and repositioning of the models as per the surgical plan.

The advent of VSP has called into question the efficacy and accuracy of Conventional Surgical Planning.

In Virtual Surgical Planning, the three-dimensional imaging enables the surgeon to establish necessary osteotomy planes preoperatively and assess different surgical scenarios.

It allows the surgeon to plan a minimally invasive surgery. It follows the osteotomy line nearly the same as in a real intraoperative osteotomy.

Surgical corrections can be undertaken with ease in Virtual surgical planning.

The Occlusion contact points can be visualized prior to the surgery which can help in planning the orthodontic treatment after the surgery.

The most important advantage of Virtual Surgical Planning that conventional surgical planning does not offer is the profile outcome of the patient post-surgery.

Profile outcome prediction aids in effective communication between the surgeon and the patient.

In orthognathic surgery, there are numerous benefits obtained by integrating VSP technology –

Obtaining an accurate and detailed representation of facial asymmetries and precise cephalometric data represents a valuable diagnostic tool facilitated by 3D models.

The technique allows for adjustments in simulating different operative techniques, which translates into customized treatment plans and better outcomes.

The VSP provides an accurate assessment of centric relation in the temporomandibular joint, which can be corrected if discrepancies occur

A major contribution provided by Virtual Surgical Planning is a more accurate evaluation of the subject's airway. Maxilla and mandible movements significantly influence the airway volume of the subject. Therefore, it should be considered in this phase of planning which cannot be considered in conventional surgical planning.
