Failures of fiber posts were mainly due to post loss of retention , while metal post failures were mostly related to root fracture , post fracture and crown and /or post loss of retention .
In conclusion , metal and fiber posts present similar clinical behavior at short to medium term follow-up .
Remaining dental structure and ferrule increase the survival of restored pulpless teeth .
The aim of this systematic review was to compare the clinical performance and failure modes of teeth restored with intra-radicular retainers .
Clinical behavior of translucent-fiber posts: a 2-year prospective study.
PURPOSE This study prospect ively evaluated the clinical performance of three types of translucent posts over a follow-up period of between 2 and 3 years . MATERIAL S AND METHODS Selected were 225 patients with one premolar in need of endodontic treatment , followed by restoration with a fiber post and porcelain crown .  The sample was r and omly divided into three groups of 75 patients each . The same type of post was used in all patients within a group : group 1 = Aesthetic Plus ; group 2 = DT ; and group 3 = FRC Postec . For bonding the post , a light-curing adhesive ( One-Step ) and a dual-curing resin cement ( Duo-Link ) were applied in group 1 and 2 roots , whereas self-curing material s ( Excite DSC as adhesive and MultiLink as resin cement ) were used in group 3 . After 6 , 12 , and 24 months , patients were recalled , and a clinical and radiographic examination was performed . For some patients , 30-month follow-up data were also collected . RESULTS Debonding of the post occurrred in eight cases ( 3.5 % ) ; in another six cases , a recurrence of the periapical lesion was reported . CONCLUSION The statistical analysis did not reveal any significant difference in the survival rate of the tested posts , suggesting that all are equally and sufficiently reliable for clinical use
