Autotransplantation of a premolar: a long-term follow-up report of a clinical case

Abstract

Introduction: This report describes the clinical management of a case in which a maxillary central incisor was lost after a traumatic injury.

Methods: A mandibular premolar with incomplete root development was transplanted into the alveolar socket of the lost central incisor.

Results: The case evolved favorably for 12 years, remaining vital to pulp sensitivity tests and developing a favorable crown-root ratio even after it was orthodontically moved.

Conclusions: Premolar autotransplantation should be considered an important and valid biological alternative in cases of premature tooth loss both in young patients and adults in order to avoid or delay implant placement or other type of restoration.
