For symphyseal fractures in the midline area, the author had devised special copings, one with a solid round shaft, the other with a larger hollow tube, figs. 11, 12. By inserting a blade on each side of the fracture and immediately cementing the copings over the blade posts and cementing the solid shaft into the hollow tube after reducing the fracture, stabilization of the fracture is accomplished and the patient can open and close their mouth during the healing rather than having to drink through a straw for six to eight weeks with inter-maxillary wiring, fig. 13. I prefer, however, to use four blades in these situations.

The author had also devised blades with a hollow threaded body instead of a neck and post, figs. 14, 15, 16, which stabilize the fracture with orthopedic plates being screwed into the hollow threaded tubes of the blades, figs. 17, 18, 19.
