Shaped for Success
  • While many fiber posts simply mimic the shapes of popular metal posts, Biolight DUAL is designed to fully benefit from fiber technology
  • The larger coronal tapers dramatically improve adaptation throughout the length of the canal
  • The large coronal diameter increases strength, support and stiffness where the post bonds to the core
  • The conservative .02 taper in the apical portion minimizes tooth structure removal
  • The overall shape offers a superior adaptation to the canal, minimizes the removal of dentin, and keeps the resin cement layer (the weakest link) to an absolute minimum

Superior Physical Properties

The materials used to make Biolight DUAL posts continually excel in independent studies and evaluations.

Superior Fatigue Resistance

Tested to 2,000,000 cycles of resistance to failure in fatigue testing.

When compared against popular brands of fiber posts, the Biolight DUAL post material has shown statistically superior resistance to breakdown from repeated cyclical stresses. This type of cyclical testing shows the ability of a post to stand up to the intraoral rigours of continual flex during mastication.
Fatigue Resistance Testing


Superior Fracture Resistance

In a comparative evaluation of popular fiber posts by a renown independent institute, the Biolight DUAL material was #1 in fracture resistance.

Superior Shear Modulus:

A recent independent university study comparing the shear modulus of various fiber posts produced these results.

Force required to FRACTURE post (MPa)


102.87 MPa

ParaPost® Taper Lux: 86.12 MPa
FRC Postec® Plus: 90 MPa
RelyX™ Fiber Post: 85.94 MPa
Force required to FRACTURE post (MPa)


Superior Bond

In a head-to-head independent study, when compared against an epoxy resin fiber post, the Biolight DUAL material showed statistically superior bond to popular self-adhesive resin cements.

In another comparative post study, SEM revealed that the Biolight DUAL material exhibits more surface roughness that all other posts, which contributes to the superior bonding ability.

Biolight DUAL offered the same adhesion without any surface treatment, or with treatment of either alcohol or H2O2 and silanization for 60 seconds.
Microtensile Bond Strength (MPa)


Superior Radiopacity

Simple in-house comparative testing shows that Biolight DUAL fiber posts are considerably more radiopaque than other popular high-radiopacity fiber posts.
