Por qué importa

Este artículo presenta dos casos clínicos sobre la coronectomía de molares inferiores en íntima relación con el nervio alveolar inferior, una alternativa a la extracción convencional para prevenir daños neurológicos. La extracción de terceros molares inferiores puede resultar en complicaciones transitorias o permanentes en el nervio alveolar inferior, afectando a un porcentaje significativo de pacientes. La coronectomía, al seccionar la corona y dejar la porción radicular intacta, busca mitigar este riesgo. Los casos revisados mostraron una mínima migración radicular y cambios de angulación sin complicaciones postoperatorias durante un seguimiento de doce meses, sugiriendo su consideración en casos seleccionados para salvaguardar la integridad del nervio alveolar inferior.

Abstract original

Damage to the inferior alveolar nerve (IAN) secondary to the extraction of the lower third molar (LTM) is a relatively frequent complication (0.35–8.40%) that can cause temporary or permanent nerve damage. Coronectomy has been proposed as an alternative, which consists of sectioning the coronary portion of the LTM, and deliberately leaving the radicular portion with the pulp intact. Two clinical cases are presented in this article, in which root migration (0–0.3 mm) and a change of angulation (+2° to +9°) occurred. None of the cases developed complications during the follow-up period (12 months). Therefore, coronectomy is a procedure to be considered in selected cases as an alternative to conventional exodontia of the LTM to avoid possible damage to the IAN.
