How can one minimize bony step during a genio osteotomy?

• A. Make osteotomy perpendicular to the occlusal plane
• B. Make osteotomy parallel to occlusal plane
• C. Make osteotomy at an angle to the occlusal plane
• D. Make osteotomy in the midline

Answer: (B)

Minimizing bony step during a genio osteotomy is best achieved by making the osteotomy parallel to the occlusal plane. When the osteotomy is parallel, it allows for an even and consistent adaptation of the bone segments post-surgery, thereby reducing any discrepancies that could lead to bony irregularities, such as steps or height differences between the bone fragments. By aligning the osteotomy with the occlusal plane, the surgical technique maintains the natural contour and relationship of the mandibular symphysis to the adjacent anatomical structures, further promoting healing and aesthetic outcomes. This method ensures that when the bone is repositioned, it fits snugly without creating gaps or uneven surfaces that need additional correction. Other approaches, such as making the osteotomy perpendicular or at an angle to the occlusal plane, could lead to misalignment during the repositioning of the osteotomized segments, resulting in potential bony steps or irregularities that compromise the final surgical result. Similarly, performing the osteotomy in the midline does not guarantee that the angle or orientation will result in a smooth transition between bone segments, which is critical for minimizing step formation.
