Abstract

Although fiber-reinforced posts have been widely used, they sometimes fail to obtain sufficient retention because of an extremely large canal space. To address this, several techniques have been introduced including relining of the fiber-reinforced posts. Here, we used a relined glass-fiber post to increase retention and fitness to the root canal in a crown reattachment case. The relining procedure was performed by using an indirect method on the working cast. This case also highlights the esthetic concerns regarding dehydration of the attached crown fragment.

Figure

• 

  Figure 1 A 16 year-old male patient presented to the clinic with trauma and a complicated crown fracture of the left maxillary canine.

• 

  Figure 2 The fractured surface was neatly separated. The labial margin was present 1 mm below the marginal gingiva, and the lingual margin was positioned supragingivally.

• 

  Figure 3 After endodontic treatment and post hole preparation, a glass fiber post (ø 1.5 mm, Luxapost, DMG) was inserted into the canal. However, the post was too small to fit the root canal.

• 

  Figure 4 Glass-fiber post relining was performed on a working cast.

• 

  Figure 5 The relined fiber post was then attached to the fractured segment on the working cast.

• 

  Figure 6 Fractured fragment replacement revealed that the fragment color was brighter because of dehydration.

• 

  Figure 7 The dehydrated tooth color returned to normal, and the marginal gingiva had healed normally by the one week follow-up exam.

• 

  Figure 8 The treatment was determined to be aesthetically and functionally successful after 12 months of follow-up.

• 

  Figure 9 The fractured segment and relined post integration were well maintained at the 12 month follow-up radiographic examination.
