BACKGROUND: The aim of this study was to highlight the connection between orthodontic difficulty before surgical treatment and in the transient malocclusion as evaluated by the mean of the of Complexity, Outcome, and Need (ICON) Score and total treatment time in surgery-first approach (SFA).
METHODS: For each patient, the ICON Score was evaluated preoperatively and on the 3rd postoperative day in order to assess the orthodontic difficulty of presurgical occlusion and the transient malocclusion.
RESULTS: Our group of patients at the preoperative stage showed score values between hard and very hard with only one patient scored as “easy” and nine “medium” patients. All scores lowered after surgical treatment. This confirms that the surgery first approach can change a malocclusion from not orthodontically treatable to an orthodontically treatable one. In our study, this was objectified by improvements in the ICON Score.
CONCLUSIONS: In the conventional three-phase approach of orthognathic surgery the total treatment time found in literature is around 18-36 months. In our study, even the most difficult cases do not have a duration of more than 15 months This demonstrates that the surgery-first approach can reduce the total treatment time even in more severe cases.
