Maxillary Advancement Reduction Maxillary advancement reduction is a specialized jaw correction procedure used to improve the position, balance, and relationship of the upper jaw with the surrounding facial structures. It may be considered when the upper jaw is positioned too far forward or when there is an imbalance affecting facial appearance, bite, or jaw function. The procedure is carefully planned according to the patient’s facial proportions, dental alignment, jaw relationship, and functional requirements. Depending on the individual case, treatment may help improve facial harmony, chewing function, bite alignment, and overall jaw balance. Proper evaluation with clinical examination and appropriate imaging is essential to determine whether maxillary advancement reduction is suitable.
