What does “Implant insertion torque” mean?
Implant insertion torque is the rotational force needed to turn an implant body into bone and is one source of information about initial mechanical fixation at placement.
What does the number represent?
It is usually expressed in N·cm and is affected by bone condition, preparation of the implant site, and implant shape. It represents rotational resistance during surgery, not a direct measure of subsequent bone integration or success rate.
Relationship to prosthesis connection timing
Primary stability is important when considering immediate loading. However, the decision also considers the site, bone and soft tissues, prosthetic force control, and patient risks rather than insertion torque alone. One torque threshold does not apply to every situation.
It differs from prosthetic screw tightening torque
Insertion torque is measured when the body enters bone; prosthetic screw torque is the tightening value when connecting an abutment or prosthesis. Their purposes and criteria differ, and a higher number does not always mean a better outcome. Follow the requirements of each system.
Frequently Asked Questions
Does high torque mean osseointegration is complete?
No. Mechanical fixation immediately after placement and osseointegration formed through healing are different processes.
Can torque alone show whether I can use the tooth the same day?
No. Placement site, prosthesis design, bite, and healing conditions are considered together with primary stability.
