Correcting a Protruding Lower Jaw: The bone in the rear portion of the jaw is separated from the front portion and modified so that the tooth-bearing portion of the lower jaw can be moved back for proper alignment.

Protruding lower jaw is corrected in a procedure called mandibular setback surgery. The tooth-bearing portion of the lower jaw is separated from its base and moved backward for proper alignment. In a similar way, receding lower jaw, or “weak chin”, is corrected with mandibular ADVANCEMENT surgery.

Retrognathia (reh-trow-NA-thee-uh) refers to a receding chin where your lower jaw sits much further back than your upper jaw. It’s a common type of malocclusion where your upper and lower teeth don’t fit together the way they should.
