Re-tightening, as the manufacturer states it
Nobel Biocare states no re-tightening interval in the torque guides, IFU1001, IFU1093, the NobelParallel CC manual or the All-on-4 manual we read.

WHY THE SCREW LOOSENS
You torqued it. Then the metal settled.
Torque creates preload — the clamping force that keeps abutment and implant pressed together. Microscopic peaks on the thread surfaces flatten under that load, and part of the preload is gone before the patient leaves the chair. The literature calls it the settling effect, or embedment relaxation.

AFTER THE CLICK
The value you applied is the value the laboratory should read.
In TrazaLab the implant line on a tooth site keeps system, platform, connection, abutment and applied torque together. It travels into the Digital Rx and onto the laboratory’s per-tooth sheet. An unconfirmed torque is not blank — the laboratory sees it as a gap.

QUESTIONS
Asked before the wrench is set.
Values are quoted from manufacturer documentation and can change by component, platform and revision. Confirm the IFU for the component and lot in your hand before torquing.
01What is the abutment torque for NobelActive 3.0?+
15 Ncm maximum, not 35. The Prosthetic Torque Guide lists “Abutments for NobelActive 3.0 — Max 15 Ncm”, and IFU1001 repeats that overtightening may fracture the screw. Every other Nobel Biocare platform tightens the final abutment to 35 Ncm.
02Is the Nobel Biocare multi-unit abutment 35 or 15 Ncm?+
Both, by angulation. The straight Multi-unit Abutment is tightened to 35 Ncm with the Screwdriver Machine Multi-unit; the 17° and 30° angled abutments to 15 Ncm with the Unigrip. The prosthetic screw that holds the bridge on top is 15 Ncm in every case.
03Do these Nobel Biocare values replace the IFU?+
No. They are quoted from the manufacturer documents listed on this page, with the revision year noted. The IFU packed with your component and lot is the instruction; this page puts the values next to the treatment step and the case record.
04Should I re-tighten after ten minutes?+
The literature on the settling effect widely advocates a second application at the same value after about ten minutes, and in vitro work shows it partially restores preload. The evidence for a fixed interval is limited. The manufacturer statement for this system is quoted in the values section; where it says nothing, this page does not turn that silence into a rule.
05Where does the applied torque go after the appointment?+
In TrazaLab it is a field on the implant line of the tooth site, next to system, platform, connection and abutment. The Digital Rx carries it to the laboratory, whose per-tooth sheet prints the torque. If it was never confirmed, the packet shows “Not on Rx” instead of a number.
AFTER THE CLICK
Read the value here. Keep it in the case.
TrazaLab records the implant line with its torque on the tooth site, writes it into the Digital Rx, and shows the laboratory exactly what was applied — or exactly what was not confirmed.
