« Dental Implants: Addison’s Disease | Nobel Direct Implant Reviewed »
I have recently started doing immediate loading after my periodontist places the dental implant fixture. This has me a little worried because it is so new. One of my concerns is if primary stability has really been achieved.
I have read about Resonance Frequency Analysis being used to quantitatively
determine the primary stability of the dental implant. Are any of you asking
your periodontists or surgeons to use this? How are they determining
primary stability for you and are you confident they are accurate?

resonance frequency analysis
This is an excellent question that does not yet have an answer that is based in scientific literature. I wrote a review article that included measuring stability in IJOMI 2004 December supplement. Values reported for threshold stability for safe immediate loading vary for different implant systems from 30Ncm up to about 65Ncm of insertion torque. Very little data is available on Osstell (ISQ) values. These numbers also vary for each implant system due to different shapes and thread patterns. ISQ values for one implant system cannot be compared to another.
As a periodontist doing most of my own immediately loaded and restored provisional restorations, I have found insertion torque values more reliable than Osstell readings. I think it is certainly reasonable to ask whoever is placing the implants to supply you with some information about the implant you are about to restore. This could be as insertion torque or as an ISQ (implant stability quotient). Insertion torque can be read from the handpiece or a torque wrench used when the implant is threaded into position.
Immediate Load or Immediate provisionalization? 3i suggest the implant be inserted with 40-50nCm to be consider stable at time of placement. This makes sense when torqing their Certain internal connection implant to 20nCm. They have a great system for immediate temps/provisionals.
Ithink we have to use the term immediate esthatic instead of immmediate loading.or we can call it gradual loading.based mainly on primaly stability(implant lenght,bone quality,surgical technique,implant design)the use of RFA.is a good way to determine it, helping to decide time of loading.but still we need study for the long term survival of this modality of treatment.I mean how far this gradual loading affect the % of oesseointegration.onr other factoe which should not be ignor whil thinking of (immediate loading )is patient occlusion .
