Testing for Osseointegration: what torque values to you recommend?

Simple one , there are a few ways but Osstell is the one I rely on , not just the extensive research backing it but my personal experience .... Peter

There are a number of different methods but I feel the best after the initial cost is the Osstell system which you can really rely on . Regards Peter

Testing the implant for integration can be done in several ways. ISQ, Periotest are devises that can help in the predictability of oseointegration. Hence they can be questionable and sometime not reliable. An easy and affordable test is the ‘reverse torque test’, but still risky and unpredictable. For your benefit, here is a publication on this topic by Misch et al. J Oral Implantol. 2000;26(2):82-90. Reverse torque testing and early loading failures: help or hindrance? Jividen G Jr1, Misch CE. Hence, I am sorry to say that you must be a member of the AAID to benefit from this publication (JOI).Enjoy the reading Gilbert Tremblay

Torque tells you nothing after initial placement - forget about it. The "tuning fork" is the implant. Turn the music down and tap the implant with a mirror handle. High pitch ring means integration. Low pitch "thud" (like a tooth) means fibrous encapsulation. Presence of osseointegration does not necessarily mean "good implant" that is ready to handle serious loads. Best indicator of quality of implant support is Osstell, with x-rays a distant second. X-rays and tap test are good enough unless you are in a hurry to load the case. Osstell is really for the hurry-up cases where you want that implant loaded ASAP and you need a measure of readiness to accept load.

We consider ISQ values as the only reliable test. And you have it documented because it is a number (in case of court or simillar).

implant stability is the name of the game, form day zero and up to functional usage. but it is different issue about primary stability, healing stability and functional stability. torque force is not the actual force in the mouth and therefore it is not the precise method and i think reverse torque no one would do it( but tell the other to do it is easy) . the radio frequency analysis is more preferred therefor. percussion can be deceiving, 15% of bone formation give the same sound, so what is the best to predict stability< the question is missing something, what kind of stability , primary then ISQ but do not forget osseo- integration by definition describing functional implant . and what predict a successful functional integration is understanding the whole subject and not only apiece of metal that not vibration when we measured it for seconds for a life function device
