Rehabilitation to crown-root fracture by fragment reattachment with resin-modified glass ionomer cement and composite resin restoration.

Tooth fragment reattachment in cases of enamel/dentin fracture is based on adhesive protocols and is indicated because of its technique simplicity. Complex cases of root fracture or extensive coronal damage demand the integration of biological properties with the mechanical characteristics of the restorative materials. This paper is a report from one patient with a favourable result that addresses the clinical procedures involved in the association of resin-modified glass ionomer cement and composite resin for cases of coronal fracture of anterior teeth with invasion of the periodontal biological space and/or proximity with the pulp tissue. The research-based background for establishment of the treatment plan is discussed and a case of crown fracture with root involvement in a maxillary central incisor illustrates the operative technique of tooth fragment reattachment. After 1 year of follow up, the clinical and radiographic findings demonstrate that the adopted clinical protocol was successful and yielded an excellent pulp and periodontal response as well as maintenance of function and aesthetics.
