What does the RTT (Reverse Torque Test) involve according to Carr and Larson in 1995?

The Reverse Torque Test (RTT) as described by Carr and Larson in 1995 specifically involves applying a counterclockwise torque to assess the stability of dental implants. The correct answer indicates that the test is performed using a torque range of 10-20 n-cm of force. This measurement is crucial for evaluating the retention of the implant immediately after placement, as it provides insight into the primary stability of the implant within the bone.

The indicated torque range is intentionally low to ensure safety during the test, as excessive force could damage the implant or surrounding bone tissue. The RTT is especially important in implant dentistry because it helps practitioners judge whether the implant is adequately secure to withstand the functional forces associated with chewing and other activities.

Other options suggest torque values or directions that do not align with the established parameters in the foundational work by Carr and Larson. Options indicating higher torque values or different rotational directions would not accurately represent the RTT methodology outlined in their study.
