Conical Connection Transfers & Analogs

What are conical-connection transfers and analogs, and when should I use them?

Transfers are impression components that record the implant’s conical interface intraorally; analogs replicate that interface in the model. Use open-tray transfers for multi-unit, divergent, or full-arch cases where pick-up accuracy matters; choose closed-tray transfers for single units and straightforward access. Always match the same conical platform across transfer, analog, abutment/Ti-base, and screws, and document torque and lot numbers for traceability.

Conical Connection Transfers & Analogs FAQs

Open-tray vs. closed-tray—how do I choose?

Use open-tray (pick-up) transfers for multi-unit, full-arch, or divergent implants to preserve spatial accuracy. Choose closed-tray for single units or when access limits the pick-up technique.

Do analogs need to match the exact platform?

Yes. Select platform-matched conical analogs so the model reproduces the connection geometry and depth precisely, supporting passive seating and correct torque behavior.

Can I mix conventional impressions with digital workflows?

Yes. Many cases use transfers/analogs to create the master cast, then scan the cast or transition to Ti-bases (CAD/CAM) for digital design. Maintain one platform throughout.

Are torque values relevant for impression copings?

Some transfer screws have recommended torque—follow the IFU to avoid distortion or movement during impression. Record lot numbers and torque in the case notes.

When should I prioritize open-tray for accuracy?

For full-arch conversions, angulated implants, or when parallelism is limited, open-tray pick-up helps preserve 3D relationships and eases framework fit.

Are these components sterile and traceable?

Yes. Surcam supplies components sterile (where indicated) with lot tracking and IFUs for audit-ready documentation.
