Resumen
Introduction: Definitive primary crowding must be treated early by means of space management in the dental arches using orthodontic appliances. The aim of this article was to report a case of interception of the definitive primary crowding using an expansionist protocol. Methods: A male patient with eight years and one month old was diagnosed with lack of space for irruption of permanent maxillary and mandibular lateral incisors, constriction of both maxillary and mandibular dental arches and wide buccal corridors. The orthodontic treatment planning consisted in perform RME using Hyrax expander and SE of mandibular dental arch with the Schwarz appliance. Results: After 1 year and 8 months of treatment, the space for irruption and the alignment of both permanent maxillary lateral incisors and permanent mandibular left lateral incisor were obtained. The mandibular right permanent lateral incisor irrupted centered and rotated in the alveolar bone. A lip bumper (LB) was used to obtain further space for the alignment of that tooth. Both maxillary and mandibular dental arches widths increased significantly and the buccal corridors widths decreased, promoting an improvement in smile esthetics. Conclusion: Association of RME and SE of the mandibular dental arch was effective in space management and contributed to the irruption and the partial alignment of the permanent incisors and the improvement of smile esthetics. If necessary, both a LB and/or a Nance’s lingual arch can be used in order to obtain further space to the alignment of mandibular permanent incisors.
