Background: Supernumerary teeth are developmental anomalies caused by excessive cell proliferation in the dental lamina or by continuing bud formation in the enamel organ. There have been instances where supernumerary teeth lead to cystic formation, aberrant diastema, crowding of the affected region, anterior crossbite, delayed or blocked eruption of succedaneous teeth, displacement or rotation, and occasionally eruption into the nasal cavity. Upon encountering an anterior dental crossbite, different treatment options can be implemented, including the use of tongue blades, reverse stainless-steel crowns, fixed acrylic devices, bonded resin-composite inclines, and removable acrylic appliances equipped with finger springs.
Case description: This particular case report illustrates a unique instance of correcting an anterior crossbite in the mixed dentition stage, induced by supernumerary teeth, in a 10-year-old boy through the application of removable Planas direct tracks (PDTs).
Conclusion: Early surgical intervention and minimally invasive orthodontic forces may be utilized to address potential occurrences of such situations with minimal disruption to the adjacent oral structures.
