Conservative Management of the Horizontal Root Fracture in the Middle Third using Fiber Post as an Intraradicular Splint

Abstract

BACKGROUND: Root fractures are uncommon injuries in permanent teeth and account for only 0.5–7% of dental trauma. It occurs more frequently in fully erupted permanent teeth, in which the completely formed root with closed apices is solidly supported in the bone and periodontium. This may lead to complex consequences due to the combined damage to the pulp, dentine, cementum, bone, and periodontium. They are transverse to oblique in direction and result from a horizontal impact. Their incidence is more in the middle third of the root than at the cervical and apical thirds.
 CASE REPORT: This paper describes a case of complicated horizontal root fracture at the middle third of the maxillary right central incisor. After receiving an endodontic treatment, the fractured root fragments of the maxillary right central incisors were united with the help of a glass fibre post. Eventually, the incisor was restored with a zirconia crown.
 CONCLUSION: Follow-up after a year revealed a well-stabilized assembly of the root fragments and the post.

A three-dimensional finite element analysis of stress distribution in maxillary central incisor with a horizontal mid root fracture after various management protocols

“…In Model 4, the coronal and apical fragments of the root were splinted using fiber post and apical 5 mm was filled with gutta-percha, which was one of the management protocols in the past literature. [ 23 24 25 ] The stress concentration was more at the fracture junction around the post with maximum value of 5.60 MPa and also at the palatal end of the coronal fragment but less when compared to Model 2 and 3 in that area. The stress distribution pattern was different from that observed in an intact tooth with fiber post and core.…”
