Reattachment of a fractured permanent molar cusp: a 12‐month follow‐up

Abstract

A posterior crown fracture due to acute trauma is an uncommon type of dental injury. This case report presents combined endodontic-bioadhesive treatment of a complicated crown fracture of a permanent molar due to a horse riding accident. Endodontic therapy was initiated following surgical removal of the fractured mesiolingual cusp, which was stored frozen until bonding procedures could be carried out. Subgingival and proximal contours of the missing cusp were maintained by an interim glass-ionomer restoration during endodontic therapy. Following root-canal obturation, the fractured cusp was reattached using a total-etch adhesive and composite resin system. The patient was recalled at 1, 3, 6 and 12 months, demonstrating excellent clinical and radiographic findings.

The importance of soft tissue examination in post‐traumatic decision‐making: A case report

“…With advancement in dental bonding technology, reattachment of fractured fragments with excellent results has been possible (3,13,14). Although laboratory studies have shown that reattached teeth may demonstrate 20–60% less fracture resistance than that of intact teeth (15,16), bioadhesive reattachment of fractured fragments should not be regarded as a long‐term provisional solution because of acceptable clinical retention rates, when proper adhesive and restorative techniques are used (17).…”

“…A posterior crown fracture due to acute trauma is an unusual type of dental injury [5]. Fractures that cross both marginal ridges usually involve pulp and may extend apically into the root.…”
