Experimental group:The position and direction of the osteotomy line were digitally designed for the patients who underwent maxillary Le Fort type I block osteotomy in the experimental group, and the i
Control group:The control group used digital design to plan the position and direction of the osteotomy line before surgery, but used free hands to complete the osteotomy operation during the operatio
