Dental Implant Torque Guide

Dental Implant Torque Guide

Dental implant torque guide is a quick cheat sheet that provides most of the popular denatl 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.

Steri-oss replace external hex .030 healing abutment?? Seems like should be .050 from above. DT thread

Dental implant screw and torque research

35Ncm to 70Ncm

Less than 35Ncm=cover screw and cover to let heal

Immediate load=immediate and early=6weeks

  • 20Ncm for immediate load
  • 10Ncm for early loading

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.

Morse taper abutments have tightest fit. Let in less bacteria 1
Microleakage Morse taper<internal-hexagon<internal-trilobe<external-hexagon

Ti performs better than Zi WHEN have horizontal mismatch

5 year posterior Zi or Ti same 1

Vertical misfit Zi and Ti doesn’t matter

Splinted success rate better than non-splinted 1 2

Conical connection subcrestal with platform switch Oct 12

Ankylos Plus connection very little leakage 1
