Plasma-treated lenowoven polyethylene ribbon was used for splinting between teeth around osteotomy lines in anterior segmental dentoalveolar osteotomy. This fixation was continued for 2 to 3 months, during which there was no damage or fall of the ribbon. In addition, the patients were able to eat their usual food, had much less pain in the teeth and oral mucosa, did not feel uncomfortable in the mouth, had no tooth damage or carious teeth, and had a good aesthetic appearance. In all eight jaws (five patients), accurate and strong bone fixation was achieved based on the planned occlusion. Patient complaints and pain were obviously less with this method than other methods. Polyethylene ribbon is quite useful for bone fixation in anterior segmental dentoalveolar osteotomy.
