Fratura horizontal radicular em incisivo lateral superior esquerdo: uma abordagem de tratamento multidisciplinar

Abstract

ABSTRACT Horizontal root fractures represent a clinical challenge as they affect anterior teeth, compromising esthetics, function, and the patient’s quality of life. Although relatively uncommon, accurate diagnosis and multidisciplinary treatment planning are essential for tooth preservation and therapeutic success. This case report describes the clinical management of a 19-year-old male patient, victim of a motorcycle accident, who presented a horizontal root fracture in the maxillary left lateral incisor. The adopted protocol involved surgical extrusion of the remaining root, followed by endodontic treatment using the single-cone obturation technique and subsequent cementation of a glass fiber post with dual-cure resin cement. The restorative phase included coronal reconstruction with incremental composite resin, aided by a silicone guide obtained from a diagnostic wax-up, which ensured greater esthetic and functional predictability. After finishing and polishing, the restoration achieved satisfactory esthetic integration with adjacent teeth and functional recovery, along with the onset of periapical bone neoformation consistent with physiological repair. This case highlights that a conservative approach integrating Endodontics, Restorative Dentistry, and Esthetics is a predictable and effective alternative for preserving anterior teeth affected by horizontal fractures, providing functional and esthetic results and restoring patient self-esteem.
