Abstract

The aim of this study was to investigate the aesthetic results of orthodontic treatment in Class II individuals. Seven Caucasian females were randomly selected, subjected to corrective orthodontic treatment with extraction of at least two pre-molars and initiation of treatment between 16 and 26 years of age. All patients were interviewed; their speeches were recorded and then transcribed and analyzed. Plaster models, lateral radiographs and photographs contained in records were consulted to assess five quantitative parameters: facial contour, nasolabial angle, incisors golden ratio, facial and dental midline, and smile line to incisal edge. The corrective orthodontic treatment improves facial aesthetics, changing facial soft tissue measures, smile and personal relationships. It was concluded that the qualitative and quantitative research are complementary, because an analysis of results based only on one parameter can mask the actual outcome and reveal aspects partially. The qualitative analysis indicates that different facial angles and proportions of what is proposed as scientifically aesthetic does not interfere with the results of treatment, provided that the facial perception of the subjects involved meet the standards of normality and accepted by them and those set by society.
