Background:

Virtual surgical planning (VSP) is widely used, but the underlying digital simulation modeling methods are often undescribed.
Understanding these methods is crucial for effective clinical application and improved surgical outcomes.

Approach:

A literature review was conducted on two main categories of VSP modeling techniques: contour-based planning and occlusal-based planning (OBP).
Contour-based methods include mirroring, templating from normative databases, and landmark extrapolation.
OBP focuses on functional occlusion for reconstructive and orthognathic procedures.

Key Points:

Mirroring is ideal for unilateral defects requiring high contour accuracy.
Normative data methods suit bilateral defects or craniofacial dysmorphies with asymmetry.
OBP is essential for alveolar margin resections and standard orthognathic surgeries.

Conclusions:

The selection of VSP modeling methods depends critically on the specific defect type and the primary goals of the surgical reconstruction.
Complex cases, like clefts, may necessitate a combination of OBP and normative data approaches for optimal results.
