Baotian didn't do orthodontics before surgery, and the occlusion after surgery is definitely not ideal, including what you said, that is, the upper lip can't wrap the lower teeth. You didn't go through the process of removing the upper teeth before the operation, and the upper teeth must be quite serious after the operation. The problem of buckteeth can be solved by orthodontic maxillary tooth retreat after operation. In addition, I want to know what kind of surgery you have, and have you ever had maxillary descent?
