Class II division 1 correction with maxillary second premolar extractions. Case report

Abstract

Introduction: Class II-1 can be the result of a retrognathic mandible, a prognathic maxillary or both. Nowadays, there are several ways for class II treatment: maxillary fi rst bicuspid extractions that can also include the extraction of one lower incisor or the fi rst or second mandibular bicuspids, depending the case, or even the extraction of the second maxillary bicuspids as well. Objectives: To achieve canine class I, correct the midline discrepancy, the excessive overjet and to improve the patient’s aesthetics. Case report: Female patient of 32.6 years of age who had a previous orthodontic treatment with extractions of the fi rst maxillary and mandibular bicuspids presents absence of the maxillary second bicuspid, generalized mild chronic periodontitis and previous mental foramen fracture with mentoplasty. Conclusions: The 2nd bicuspid extraction was the best alternative to avoid another surgery, with a signifi cant change in the patient’s profi le, improving her expectations and self-esteem.Key words: Class II-1, second maxillary bicuspid extractions.
