IAN should be protected. Impacted 3rd s are are removed at this time. Bony interferences are removed with bur, to allow for passive contact of the two segments. A clamp may be placed on the proximal segment for manipulation to verify removal of all interferences. Proximal and distal segments are now independent.
Contralateral split is performed identically.
Interocclusal splint is placed and MMF applied. If rigid internal fixation is to be used screw holes are drilled. Percutaneous approach maybe used. 3 long triangulated screws are ideal. Site of extracted third molars pose a challenge for screw fixation.
