Renfert Bi-Fix-Pin 100 Pieces (Item No. 3451000)

A die that rotates in its seat is a restoration that will need adjusting at the chair.

Single-pin models have one weakness: nothing stops the die from turning. The rotation may be a degree or two — invisible on the bench, but enough to shift a margin or throw off a contact by the time the case is finished. Drilling adds its own variables, since every hole is only as accurate as the drill setup and the technician's hand that day.

The Renfert Bi-Fix-Pin (Item No. 3451000) addresses both problems at once. It is a dual-guidance model pin with an integrated fixing wire, positioned directly in the impression. Two guidance pins prevent rotation, and no drilling is required — which removes a step from model production and a source of error along with it.

Designed for Accurate Model Fabrication

The Bi-Fix-Pin's two guidance pins hold the die against rotation, so positioning is stable and repeatable every time the die is reseated. The integrated fixing wire secures the pin during impression and model fabrication, keeping it where the technician placed it while the material sets.

Key features include:

• Dual-guidance design — two pins prevent the die from rotating in the base
• Integrated fixing wire — holds the pin in position during impression and model work
• No drilling required — positioning happens in the impression, not after
• Faster model production — one fewer step per die
• Repeatable positioning — consistent seating across reseatings and across cases
• Pack of 100 pieces — practical quantity for routine laboratory use

Why Skipping the Drill Matters

Drilling pin holes is a step where small inaccuracies compound. Hole angle, depth, and position all vary slightly, and each variation transfers into how the die sits. Because the Bi-Fix-Pin is set directly in the impression, that entire class of error is removed from the workflow — and so is the time spent drilling, clearing debris, and checking each seat.

Practical advantages include:

• Greater positioning accuracy through dual guidance
• Improved stability with anti-rotation guidance
• Faster fabrication because drilling is not required
• Consistent results across multiple models
• Simplified handling during model production

Suited to Everyday Laboratory Workflows

The Bi-Fix-Pin fits standard removable-die and fixed prosthodontic model workflows without special equipment. For laboratories that already pin conventionally, it slots into the existing process while shortening it — which makes it straightforward to adopt case by case rather than all at once.
