ABSTRACT

AIM: This study compared the different views between orthodontists and oral maxillofacial surgeons, as for smile analysis in patients subjected to orthognathic surgery.
METHODS: Thirty individuals who had undergone orthognathic surgery and had a minimum postoperative period of 6 months were selected. Posttreatment frontal smile photographs were obtained and examined. Smile features were recorded by 4 professionals (2 orthodontists and 2 surgeons) and the agreement between them was assessed.
RESULTS: The subjective analysis of smile as well as the observation of incisal and gingival exposure showed a statistically significant agreement percentage between the two groups. Nevertheless, no agreement was seen between the surgeons, while evaluating the buccal corridor and the parallelism between the incisal edge of antero-superior teeth and the lower lip. Significant agreement percentage (60%) was seen only between the orthodontists regarding the smile arch parallelism.
CONCLUSIONS: Professionals must be alert as for facial analysis, mainly in terms of smile harmony, so that the orthognathic surgery will satisfactorily reestablish the facial esthetics in all the parameters outlined.

Keywords: smile, esthetics, harmony, interdisciplinary analysis.
