When is a coronectomy typically performed?

• A. For vertically impacted teeth
• B. For horizontally impacted teeth
• C. For teeth with apical resorption
• D. For teeth with significant mobility

Answer: (A)

A coronectomy is typically performed on vertically impacted teeth, particularly when there is a risk of damaging the inferior alveolar nerve during the extraction process. This method involves removing the crown of the tooth while leaving the roots in place to prevent complications such as nerve injury. This approach is especially indicated in cases where full extraction could lead to significant morbidity. This procedure is also indicated in situations where the tooth is deeply impacted and conventional extraction poses high risks. By leaving the roots behind, the procedure minimizes potential damage to surrounding structures while still addressing issues such as infection or the need for orthodontic realignment. While horizontally impacted teeth might present their own challenges, they are not the primary focus for coronectomy. The other conditions like apical resorption and significant mobility indicate different clinical scenarios that would not align with the rationale for performing a coronectomy. Apical resorption might necessitate endodontic treatment rather than extraction, and mobility suggests periodontal issues that would not typically require such an intervention.
