What it Corrects: It treats an underdeveloped lower jaw (severe overbite/retrognathia) or an overgrown lower jaw (severe underbite/prognathism).The Procedure: The surgeon makes incisions behind the molars on both sides of the lower jaw.

This sliding technique ensures that the bone segments remain in maximum contact with each other, promoting rapid healing once the titanium screws are placed.3. Double Jaw Surgery (Bimaxillary Osteotomy)As the name suggests, this is a comprehensive, simultaneous surgery on both the upper and lower jaws. What it Corrects: Bimaxillary surgery is reserved for complex, multi-dimensional deformities where moving only one jaw would not achieve a functional bite or aesthetic balance. It is also the primary surgical
