Deviation from the dental midline affects the dentoalveolar complex, and occurs when there is an imbalance between the teeth and the apical base, of the right and left hemiarch or between the upper and lower teeth. The use of microscrews as anchorage units, in addition to canceling undesirable side effects, simplifies orthodontic mechanics, provides greater predictability of treatment results, provides greater comfort and aesthetics to the patient, reduces treatment time and allows for correction of cases with tooth loss, as it provides direct anchorage. The main objective of this work was to demonstrate, through a clinical case report, the correction of midline deviation asymmetry and better facial harmony with the use of asymmetric extraction of premolars and the use of titanium orthodontic microscrews as anchorage.
