Which orthognathic procedure is considered most stable?

Mandibula down
Maxilla up
BSSO
LeFort I

The correct answer is: Maxilla up

Maxilla up is considered the most stable orthognathic procedure because moving the maxilla upward allows for a more stable occlusion and better long-term stability compared to other procedures. By repositioning the maxilla in an upward direction, the relationship between the upper and lower jaws can be improved, leading to better function and aesthetics. This procedure is commonly used to correct conditions such as Class III malocclusions, asymmetric facial features, and open bite deformities, providing predictable and stable results over time. Option A (Mandibula down), Option C (BSSO), and Option D (LeFort I) are not as stable as maxilla up in terms of orthognathic surgery outcomes. Mandibula down and other mandibular procedures may not provide the same level of stability as repositioning the maxilla. The BSSO (Bilateral Sagittal Split Osteotomy) and LeFort I procedures are important surgical techniques; however, they are not specifically focused on addressing stability in the same way as maxilla up procedures.
