Expect the same physical properties and features as other Biolight® posts made from the same material:
Epoxy and BisGMA-FREE
All Biolight® products are manufactured without the use of either Epoxy or bisGMA resins.

(With 12 strands of Biolight® DRILL-FREE)
• With Biolight® ST - 1.5mm (only 1 post))
• With Biolight® DRILL-FREE - 1.55mm (12 strands)
Reconstitution coronal-radicular restorations with fiber multi-posts Biolight® DRILL-FREE (12 strands) resist to rupture tensile forces higher than
120% compared to those reinforced with structured fiber posts prefabricated central root canal Biolight® ST equivalent to ø 1.5mm.
Superior Fatigue Resistance
When compared against popular brands of fiber posts, the Biolight® DRILL-FREE 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.

Superior Shear Modulus
A recent independent university study comparing the shear modulus of various fiber posts produced these results:
Force required to BREAK post (MPa)
| Biolight® DUAL: |
102.87 MPa |
| ParaPost® Taper Lux: |
86.12 MPa |
| FRC Postec® Plus: |
90 MPa |
| RelyX™ Fiber Post: |
85.94 MPa |
Force required to BREAK 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.
Superior Radiopacity
In an independent university study, The Biolight® DUAL material against exhibited superior radiopacity to all other fiber posts tested:
Radiopacity of fiber posts
| Biolight® DUAL: |
205.90 |
| FRC Postec® Plus: |
106.67 |
| RelyX™ Fiber Post: |
88.04 |
| ParaPost® Taper Lux: |
64.67 |
Radiopacity of fiber posts
Simple in-house comparative testing shows that Biolight® DUAL fiber posts are considerably more radiopaque than other popular high-radiopacity fiber posts.
