What is the difference between the multi-unit abutment and implant-level connections?

NobelProcera can connect to the implants in two ways, and a single full-arch bridge can use both in the same arch (for example, multi-unit abutments on the anterior and direct-to-implant on the posterior, as in one ROE FP2 case). Understanding the connection type matters for both delivery and records.

Connection How it connects
Multi-unit abutment level The zirconia interfaces directly to the multi-unit abutment, held by a screw. There is no coping and no adapter at these sites.
Implant level A gold-colored, friction-fit metal insert (adapter) seats into the zirconia bridge; the adapter engages the implant and is held by the screw. It is a press fit, not cemented.

Inserts and screws: At implant-level sites the gold metal insert is a press fit that seats with an audible click and is held by friction with no cement. ROE pre-fits these inserts in the lab, but it is good practice to seat them yourself before delivery so you know how they feel and fit.

Screw selection differs by connection: in a mixed arch, the posterior direct-to-implant copings use long screws, while the multi-unit sites use standard Nobel prosthetic screws. Confirm the correct screw for each connection type before delivery. For a visual, see ROE's "The Process and Components for Seating a NobelProcera Bridge" video on the product page.
