Angulated Custom Cast Post and Core Restoration for Traumatised Anterior Tooth-?Not as Straight as an Arrow?

摘要

Traumatic dental injuries are most common injuries afflicting young children and generally involve the maxillary anterior teeth. Increased overjet with protrusion of upper incisors and insufficient lip closure are significant predisposing factors to traumatic dental injuries. Anterior tooth trauma leads to discomfort and serious psychological, aesthetic, functional, and phonetic problems that can affect social relationships. Treatment of a traumatically injured single central incisor poses significant challenges to the dentist and the patient. The reduced tooth structure makes retention of extra coronal restoration difficult. The purpose of cast post is to provide retention for the core restoration, which replaces the lost coronal tooth structure. This case report describes aesthetic rehabilitation of a fractured labially inclined left maxillary central incisor. Aesthetic and functional reconstruction was achieved by customising the axial inclination of the core followed by cementation with Porcelain Fused to Metal (PFM) crown. Thus, endodontic approach combined with prosthodontics provides a quick, reliable and economic treatment option.
