What is Trilor?
Trilor is a dry-millable fiber-reinforced resin material designed for dental understructures, including bars for full arch restorations, bridge frameworks, single crown copings, and denture bases. This super-strong resin flexes and bends under stress and bonds easily to titanium
and Crystal Ultra making it an ideal support material for implant restorations.
Trilor was created as an understructure material to support either hand-layered porcelain superstructures, bonding of resin teeth, or most importantly, as a structural "bar" support for the new class of milled nano-hybrid ceramics such as Crystal Ultra. Currently, Crystal Ultra is the only nano-hybrid ceramic material that comes in disc form for long-span and full arch bridges. However, in many full-arch cases, the final restoration cannot be designed with adequately sized connectors so a sub-structure is created to provide additional strength and durability.
Prior to the introduction of Trilor, most full arch substructures were historically milled from titanium, which is difficult to mill and which, due to it's stiffness, transfers undesired chewing energy to the implants. Similar to Crystal Ultra flexing properties, Trilor's resin component allows the substructure material to bend and flex in the mouth transferring less energy to the implants and potentially leading to fewer long-term implant failures, which is especially important when only four implants are used per arch.

Trilor Compared to Trinia
Trilor is sometimes compared to Bicon Trinia, which is also a resin material used for substructures. Trilor, however, is a more modern engineered material and beats Trinia in every single mechanical and physical characteristic.
|Mechanical Property||Trilor||Bicon Trinia|
|Tensile strength||380 MPa||169 MPa|
|Flexural strength||540 MPa||393 MPa|
|Flexural modulus||26 GPa||18.8 GPa|
|Compressive strength||530 MPa||339 MPa|
|Charpy impact strength||300 KJ/cm2||26 KJ/m2|
|Rockwell hardness||111 HRR||125 HRR|
|Shore D. Hardness||90||92.5|
|Density||1.8 g/cm3||1.68 g/cm3|
|Short beam shear||63 N/mm2||49 N/mm2|
Zero Toxicity, No Sensisitivity, No Irritants
Trilor was tested as "zero sensitivity" according to all ISO 10993 and FDA testing standards:
- ISO 10993-3 -- non-mutagenic Tests for genotoxicity, carcinogenicity and reproductive toxicity
- ISO 10993-5 -- does not induce cytoxicity Tests for in vitro cytotoxicity
- ISO 10993-6 -- non- irritant Tests for local effects after implantation
- ISO 10993 -10 -- non-sensitizer test for irritation and skin sensitization
- ISO 10993-11 -- no adverse phycal symptoms after injection (test of systemic toxicity)
