Whilst the displacement and modelling of condyles have been identified as a potential corollary of orthognathic surgery, evidence is lacking in relation to the effects of Bilateral Sagittal Section Osteotomy (BSSO) advancement on the condylar region. This presentation will address the following questions: 1) Does the magnitude and/or direction of surgical movements influence condylar positioning or modelling? 2) Is there a difference between the VSP planned and actual translational/rotational displacements of the proximal segment? 3) Are there any patient-specific predictive factors which correlate with the above?
Learning Objectives:
After this lecture, attendees will be able to:
Recognize the translational and rotational movements of the proximal segments that commonly occur following BSSO advancement.
Describe the effects of surgical movements on condylar positioning and modelling.
Assess the accuracy of VSP planning in predicting post-surgery positioning of the proximal segment.
Evaluate the digital workflows required to accurately superimpose CBCTs on a variety of stable reference structures.
