Stability of a two piece PSI deign in splintless maxillary orthognathic surgery
Stability of a one piece PSI deign in splintless maxillary orthognathic surgery
A two piece fixation device will be used connecting the nasomaxillary and the zygomaticomaxillary buttresses on both sides
A one piece fixation device will be used extending from one zygomaticomaxillary buttress to the nasomaxillary area then just below the anterior nasal spine then to the same buttresses on the other side
