To achieve changes and harmonization of the facial profile in patients with biprotrusion, dental extractions and low friction mechanics are sometimes required to obtain stable and satisfactory results. The aim of this article is to present a clinical case of change and harmonization of the facial profile by means of dental extractions and low friction mechanics with conventional appliances. A 22-year-old female patient was presented for consultation, who reported discomfort with her appearance and smile; the clinical examination revealed a mild skeletal class III with mesofacial pattern, bi-protrusive profile, molar and canine mesioclusion, anterior open bite, mild upper crowding, moderate lower crowding and coincident midlines. The treatment objectives included: extractions of upper second premolars and lower first premolars, correction of maxillary and mandibular crowding, achieving molar and canine neutral occlusion, improving protrusion, overbite and maintaining coincident midlines.
