BACKGROUND: The aim of this study is to highlight the connection between orthodontic difficulty before surgical treatment and in the transient malocclusion as evaluated by the mean of the ICON score and total treatment time in SFA.
MATERIALS: For each patient, the ICON score was evaluated pre-operatively and on the 3rd post-operative day in order to assess the orthodontic difficulty of pre-surgical occlusion and the transient malocclusion.
RESULTS AND CONCLUSION: 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. 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.
