Premill Blanks Compared
The real difference is the range of compatible implant systems.
Both options are premill blanks with a factory-machined interface — the connection surface to the fixture is already machined to micron accuracy, and you only mill the upper profile. So the difference between the two isn't "interface quality."
The practical difference is range of compatible systems: Dentalrix covers 15 systems and Covision covers 18 implant systems. If your lab takes cases from a variety of systems, this number usually drives the decision.
More important than brand choice is that the exact part code matches your implant system and platform diameter. Tell us your system before ordering so we can confirm the right code — this is where a mistake gets expensive.

Which should you choose?
If you work with a variety of systems
Covision, compatible with 18 systems, gives broader coverage.
If you have one specific system
Either may cover your system — get the exact code from us and decide based on stock and current pricing.
Shared requirement
Milling either one requires a wet 5-axis machine with titanium capability and a dedicated premill holder.

FAQ
Which one is compatible with my implant system?
Tell us your implant system name and platform diameter and we'll give you the exact compatible code from either option.
Why not mill the abutment entirely from a titanium blank?
Because the connection surface to the fixture needs micron-level accuracy that lab milling can't guarantee. Errors at this level lead to non-passive seating, screw loosening and tissue complications.
What machine do I need to mill a premill?
A wet 5-axis mill with titanium capability and a dedicated premill holder. If your machine doesn't meet these requirements, we can suggest suitable options.
What does the code mean, e.g. C10?
It's a part code identifying the compatible system and platform. We confirm the right code for your case before you order.
