Abstract
A completely digital workflow is described for the immediate restoration of a fractured
fiber post with a digitally prefabricated definitive restoration using 3-dimensionally
printed guides. The geometric morphology and axis of the root canal were digitally
determined by using cone beam computed tomography to localize the 3-dimensional position
of the fractured fiber post. A virtual drill modeled on the shape of the fractured
post was fabricated and customized for removal of the post by using a guide to facilitate
the intraoral transfer of the drilling procedure. A titanium post-and-core and crown
had been virtually predesigned and fabricated before the procedure, and 2 digital
guides were designed for their placement. All guides were 3-dimensionally printed.
By following this workflow, the removal of the fractured fiber post and immediate
definitive restoration were completed in 1 visit, facilitating a more efficient, predictable,
and straightforward treatment.
