Clinical case on the DT Light-Post

This patient presented with a failed restoration on endodontically-treated lateral incisor (#10). There is adequate tooth structure to restore with composite, rather than a crown.

The DT Light-Post has a double-tapered, anatomic design, to provide a good fit with minimal cement thickness.

In this case, there was sufficient remaining tooth structure to avoid full coverage prosthetics, and a post was added to provide support for the direct composite restoration. After the post was placed, the old restoration was removed and a new tooth built.

In vitro research indicates that the addition of a quartz fiber post in anterior endodontically-treated teeth provides a more durable restoration with better failure modes.
