ABSTRACT
Aim:
This study compared the different views between orthodontists and oral maxillo facial 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. Post treatment 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.
