Clinical Behavior of fiber post
Clinical Behavior of Translucent-Fiber Posts: A 2-Year Prospective Study
Monticelli et al 2003
-
- Fiber posts have overcome some of the limitations of metallic posts (platinum, alloys, or titanium) concerning the esthetic appearance, mode of failure, and clinical performance
- Carbon-fiber posts for anterior roots meant to provide support to an all-ceramic coronal restoration
- Metallic posts tend to produce an irreversible root fracture on failure, if a root fracture occurs in the presence of a fiber post, it is usually located more coronally and is more easily retreatable may be due to over preparation of root for metallic post
- Clinically, treatment was considered successful when, in the absence of any radiologic sign of periapical pathology, the post and core were soundly retained and neither a root nor a post fracture had occurred
- Among all of the 225 teeth on trial, 14 (6.2%) failures were reported during the follow-up period, similarly distributed among the three tested groups
- Eight restorations failed because of debonding of the post (3.5%). Six (2.7%) of the recorded failures were due to the recurrence of endodontic periapical lesions
- In the present study, no fracture of the root or abutment was seen, and no post-dislodgment or crown debonding was recorded. Failures consisted only of post debonding, ascribed to a loss of integrity at the adhesive interface between dentin, adhesive, resin cement, and post.
