Dental Implant Torque Guide

Dental Implant Torque Guide

Dental implant torque guide is a quick cheat sheet that provides most of the popular dental implant system torque recommendations. Torque guides are great but how accurate is your dental torque wrench? Basically they are almost all wrong most of the time. Albayrak JPD 2017

Styles of dental torque wrenches

There are both electronic torque limiting devices and mechanical torque limiting devices. The mechanical devices are either friction style with a toggle or spring style with a beam.  The mechanical are much more accurate than the electric, furthermore the spring style tend to be more accurate than the friction style. Vallee JPD 2008 Britton 2014 JPD  Mechanical torque devices are almost always 10% plus or minus in the research but do tend to give lower torque levels as they age. Cap testing device like the Cap Torque Tester Series TT01 Mark10 and a 3-jaw chuck like the Precision Quick-action drill chuck from Optimum. Method is in Goldstein JPD 2020 but appears the Mark10 company has everything one would need.

Can you verify torque in your office?

Not really. We send in our torque devices to the company to have them recalibrate them but not very often and we do not use a set protocol of how long or how many uses before we do. There are things you can buy yourself to test them.

Implant driver head types vary by company.

If you leave the access with a partial filling you get more retention Emms J Pros 2007

Here are the conclusion of the research

Within the limitations of this study, we can draw the following conclusions:
  • 1 Increasing the platform diameter of implant abutments leads to an increase in retention of the casting cemented to it.
  • 2 The method employed to fill the screw access channel of implant abutmentscan have an effect on the retention of coronal restorations cemented with TempBond.
  • 3 Fully filling the screw access channel with an elastomeric impressionmaterial reduced the removal force of a coronal restoration cemented with TempBond.
  • 4 Partially filling the screw access channel with elastomeric material increased the removal force of a coronal restoration cemented with TempBond.
  • 5 Wall removal can have a significantly detrimental effect on retention form of an abutment.
  • 6 Selective wall removal can be an adjunct to retentive form of an implant abutment.

    What does Ncm stand for? At last cleaning of my full upper arch implants the torque was reduced from 15 to 13. That helped the thightness feeling I was experiencing. How much lower can torque reduced to alleviate continued feeling of tightness? I go for cleaning 1/15!! Thanks!

      Newton centimeter. The recommendation for most systems is 15Ncm if going to a multi-unit abutment (which most are). If it feels tight and loosening helps then I would think that either A there is enough misfit (there always is some misfit) that you can sense it or B the intaglio (portion of the prosthesis touching your gums) needs to be relieved. There is no way that anything on the market is accurate enough to tell 15 from 13. It is more accurate to say it’s a little less than 15Ncm according to whatever torque measuring device is being used that day. Is someone removing to clean on regular basis? Removal is not recommended unless you have some sort of issue, which sounds like you might.
