Comparison of the clinical efficacy of two different types of post systems which were restored with composite restorations

Abstract

AIMTo compare the efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts.METHODSSixty-two single rooted maxillary and mandibular central incisor teeth in forty-four patients (15 males and 29 females; age range 15-32 years) were restored either with an ultrahigh molecular weight polyethylene (UHMWP) fiber post (Bondable Reinforcement Ribbon, DENSE, Ribbond, Seattle, WA, United States) or a zircon-rich glass fiber post (Snowpost, Lot H 040; Carbotech, Ganges, France). Then, direct resin composite restoration (Clearfil AP-X, Kuraray) was performed for both post systems in tooth color suitable. Patients were recalled for routine inspections at 6 mo, 1, 2 and 3 years.RESULTSThe restorations were assessed during each recall evaluation according to predetermined clinical and radiographic criteria (periapical lesion; marginal leakage and integrity; color stability; surface stain and loss of retention of the post or the composite build-up material). The follow-up data showed no significant difference in these criteria between polyethylene fibre posts and zirconia-rich glass fibre posts.CONCLUSIONThe efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts were similar, suggesting that both types of fiber post can be used successfully to help retain resin composite restorations.

Adhesive bond integrity of Y‐TZP post with calcium fluoride infiltrated resin dentin adhesive: An SEM, EDX, FTIR and micro‐Raman study

“…15 Aesthetic posts (fiber or ceramic-based) are given preference compared with the metallic posts because of their ability to transmit light, superior biocompatibility, and lack of the ability to alter the restoration's color. 15,16 The yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) are zirconium-based aesthetic dental posts with acceptable biocompatibility. 17 The zirconia posts bear a good resemblance to the tooth color, serve as an alternative to metal restorations, and possess long-term chemical stability.…”

Effect of different post space irrigation solutions on the bond strength of two types of post restoring anterior teeth (Invitro study)

“…(14) Therefore, to create a monoblock effect that increases the tooth's resistance to fracture, the use of post material with an elastic modulus closer to that of the tooth dentine and the post's ability to bond to dentine and resin cement are both essential. (17,20) All materials utilized and investigated in the current study were used following the manufacturer's instructions. (18) Because eugenol-containing sealers could affect resin cement's polymerization and interfere with its ability to adhere, ADSEAL resin sealer was employed.…”

“…It results, after adhesive cementation with resin cement to the radicular dentin, in the formation of a monoblock effect which increases the longterm success of these restorations along with improvement in esthetics and function. (8) On the other hand, better stress distribution is provided by a custom-made post and core system than by a prefabricated glass fiber post, as the latter has multiple interfaces with different modulus of elasticity. (9,10) Therefore, a custommade post and core composed of milled polymer polyetheretherketone (PEEK) resin had good dimensional stability, biocompatibility, was simple to polish, and was machinable.…”

“…Any filling material residues left after post space preparation, could have a negative impact on this process. (6)(7)(8)(9) To ensure thorough cleaning of the canal, several dentin surface cleaning solutions are suggested, including sodium hypochlorite (NaOCl), ethylenediamine tetraacetic acid (EDTA), and chlorhexidine gluconate. In the literature, it is unclear what happens to them after post space preparation, even though their usefulness and potency during root canal preparation are well established.…”

Influence of glass fiber posts and class III direct restorations on the resistance of anterior teeth

“…On the other hand, differing from the findings obtained in this research, Scotti et al (2015) affirm that endodontically treated posterior teeth with GFP showed an increase in fracture strength. Additionally, Ayna et al (2018) report that GFP may be used clinically to aid the retention of CR restorations, increasing the resistance of the tooth/restoration set. Corrêa et al (2018) state that teeth with GFP are more prone to repairable fractures when compared to teeth with cast metal core.…”
