Dr Peter Andersson and Prof. Lars Sennerby have treated implant patients together in Italy since 1996. They have used the Resonance Frequency Analysis (RFA) technique for implant stability measurements as an integrated part of their implant protocol since the RFA technique was invented more than 20 years ago. This is not too surprising, as Prof. Sennerby was one of the developers of the RFA technique. In this interview, however, Dr Andersson took the time to present his experience with the RFA technique and described how it is used in his clinic on a daily basis.
Dr Andersson, what type of RFA instrument are you using today? And which are the advantages?
We are using the Penguin II, which has many advantages in comparison to the old wired system, not only from an economical viewpoint—since it is much cheaper. The Penguin instruments have no wires, they are small, can be kept on the surgical or restorative trays and used by the clinician without assistance. Another great thing is that the transducer pegs are made of titanium and can be cleaned and reused. Since we are treating some 200 patients with 400 to 500 implants per year and all implants are measured at least twice, a mono-use transducer peg is not an option for us from an economical point of view. The MulTipeg as used with the Penguin has a long lifespan because it can resist at least 20 autoclavings. You can really tell that the Penguin instruments are made for clinicians by clinicians.

For us, the use of RFA is part of the routine documentation of our implant cases and we find it more useful than taking a radiograph of the implant site. Through the years we have learned that the risk for implant failure increases with....READ MORE
