Facial aesthetics in orthodontics.

Author information



Current trends in orthodontic care emphasise alternatives to the extraction of premolars, despite a lack of support from the refereed literature for many of the non-extraction treatments. Anecdotal reports published in non peer-reviewed journals have called into question the aesthetic effects of extraction treatment. As calls for evidence-based treatments increase throughout dentistry, reports on the effects--both positive and negative--of different orthodontic options have appeared in growing numbers. Given the results of a variety of reports in the peer-reviewed literature, it may be concluded that orthodontic treatment involving extractions can produce improved aesthetics for many patients who have some combination of crowding and protrusion. However, careful diagnosis followed by evidence-based treatment decisions should be the accepted clinical norm as the specialty of Orthodontics embarks on its second century.
