Main Article Content
Background: Extractions are performed to improve dental alignment, facial esthetics and occlusal function. The teeth to be extracted are chosen according to the diagnosis of the case. Indications for extractions include dental crowding, malocclusions, and skeletal discrepancies. The most common extraction sequence is that of the first premolars. Extraction of the lower incisor may be considered in specific cases, but may affect esthetics and occlusal function. Asymmetric extractions can be effective.
Objective: To perform asymmetric extractions based on accurate planning and diagnosis to correct midlines, achieve class I canines, free crowding, improve upper and lower incisor proinclinations and achieve a harmonious patient profile.
Case report: 21-year-old male patient, skeletal class II, moderate upper and lower anterior crowding, right molar class II, left molar class I and bilateral canine II relationship. The decision was made to perform asymmetric extraction of the right upper first premolar and right lower central incisor.
Results: Crowding was corrected in both arches, the lower incisors were retroinclined, occlusal stability was obtained, functional class II molar on the right side, class I molar on the left and bilateral IC canine relation, overjet of 2 mm and overbite of 40%.
Conclusion: The choice of teeth to be extracted is based on a thorough analysis that considers the biomechanics of treatment, accurate diagnosis, as well as individual patient factors. The asymmetric extraction approach has proven to be effective and can result in faster and more stable treatment, provided that proper planning is performed.
