Michael Robert Norton, BDS, FDS, RCS, discusses the advantages of using an insertion torque of 25 NCm to facilitate faster osseointegration with immediate placement protocols in The Academy of Osseointegration's webinar.
Here are seven key points:
1. The webinar is part of AO's installment of the #AskAO. The webinar is titled, "Is Tight Right?"
2. Dr. Norton explains why the low insertion torque yields enhanced clinical results. Currently, the high torque is generally used to facilitate osseointegration.
3. Clinicians hit the single target value of insertion torque and use the Peak Insertion Torque as a measure of rotational stability. However, Dr. Norton doesn't agree with this method and said, "There isn’t an actual statement that can be made that PIT is a predictor of success.”
4. Rather, he believes clinicians should use a Resonance Frequency Analysis and Implant Stability Quotient as a more accurate measurement of primary stability.
5. The data currently suggests that secondary stability begins to form at three weeks. Dr. Norton claims clinicians delay biological stability by moving the primary stability up with insertion torques of 75Ncm or more.
6. Dr. Norton is not arguing the high insertion torque will necessarily prevent osseointegration. Rather, he is saying if the osseocompression creates unfavorable critical pressure in the wrong zone, this will result in marginal bone loss over time.
7. Dr. Norton believes primary stability should be defined by whatever it takes to enable successful, but rapid osseointegration between implant and bone.
"Primary stability is not insertion torque. We are not carpenters," Dr. Norton said, "It's time to think like a clinician. Think viable constraint (vC) and protect the crestal bone."
