Freitas DB, Lotif MAL, Chagas FO, Cidrão ALM

Objective: This study aimed to perform a literature review addressing the changes in orofacial aesthetics caused by orthodontic dental retraction mechanics after tooth ex-tractions in Angle division 1ª Class II malocclusion. Methods: A bibliographic survey was conducted with articles published from 1950 to 2018 in the PubMed, MEDLINE and Google Scholar databases. The keywords “Angle Class II Malocclusion”, “Aesthetics”, “Orthodontics” were used. Articles referring to orthosurgical treatment, Class I and III Malocclusions, theses, dissertations and literature review articles were excluded. Results: According to the studied literature, it was observed that there is a relationship between the retraction level of upper and lower incisors, and lip retrusion, which is accompanied by a tendency for a nasolabial angle to open, but with low predictability. Conclusion: All these changes can strongly affect the aesthetics of the lower third of the face, but without prejudice, when this treatment modality is well indicated.
