Indicate the case in which extraction of the central upper incisor is orthodontically indicated.

Indicate the case in which extraction of the central upper incisor is orthodontically indicated.

• A. Root fracture, related to dental crowding
• B. Dento-alveolar disharmony with crowding
• C. Central superior incisor impacted with enough space
• D. Class II/1 Angle malocclusion

Answer: (A)

The key idea is that removing a maxillary central incisor is reserved for cases where the tooth itself has a poor prognosis and cannot be restored. If the central incisor has a root fracture with compromised structure and vitality, attempting to save and orthodontically reposition it would risk persistent infection, failure of treatment, or unstable aesthetics. In such a scenario, extracting that tooth provides reliable space to achieve a functional and stable bite, typically followed by a planned replacement later to restore esthetics. In contrast, general dento-alveolar crowding is usually managed by moving teeth around the arch and commonly using extraction of premolars, not the central incisor, so as to preserve the natural appearance of the anterior teeth. An impacted central incisor with enough space can often erupt with orthodontic traction rather than extraction of the tooth. And a Class II/1 malocclusion is addressed with sagittal corrections (often premolar extractions or other mechanics) that do not involve removing the central incisor.
