Two methods for interlocking the segments of fixed splints are advocated: (1) solderless joints where the connector occurs between adjacent abutment teeth and (2) a locking rod and tube attachment when the connector occurs in a pontic space. The locking rod and tube attachment was described. It allows complete independence of each segment. If problems occur in any segment of the splint, only that segment must be removed to make a repair.
