Dental crowding: a review

Dental crowding is a frequent characteristic of dental malocclusion and is the reduction in the perimeter of the arch that can manifest as space closure, rotation and/or movement of the teeth. The temporary dentition is important as it guides the eruption of the permanent teeth, thus establishing the ideal occlusion; the lack of spaces can cause disproportionate sizes between the jaws and the permanent teeth. Treatment options include the orthopedic phase and orthodontic phase in which the extraction of teeth may or may not be necessary. Timely treatment with personalized planning helps us achieve correct dental occlusion, which is essential for good chewing and correct passage of the bolus, in addition to playing an important role for phonation and the aesthetic results for the patient.
