Comprehensive Analytical Interceptive Approach to Manage Crowding in Mixed Dentition: A Case Report.

Dental crowding is among the most prevalent forms of orthodontic malocclusion, commonly observed during the mixed dentition period, with the mandibular anterior region being the most frequently affected. The management of crowding during the early to mid-mixed dentition period has been described using various terms, including space supervision, eruption guidance, pre-orthodontic guidance, and interceptive orthodontics. An analytical approach from extraoral to intraoral examination, along with a mixed dentition model analysis, is vital for effective space supervision, as it helps determine the space needs, thereby aligning the erupting permanent teeth.Space supervisionis a broader term for space maintenance and preservation, maxillary expansion, disking of primary teeth, selective extraction of primary teeth, and minor tooth movements to preserve the arch dimensions and facilitate oral functions. This case report presents the diagnosis and management of a mixed dentition malocclusion case of a 10-year-old female patient with severe maxillary and mandibular incisor crowding along with anterior crossbite with a comprehensive analytical interceptive non-extraction approach sequentially applied through space supervision, including maxillary expansion, disking of primary canines, 2×4 appliance therapy, and conservation of leeway space by lingual holding arch.
