Penguin RFA: Monitor Osseointegration, Reduce Treatment Time, and Manage Challenging Cases
Penguin RFA measures implant stability and osseointegration to enhance decisions about when to load. This is especially important when using protocols with shorter treatment time or treating risk patients.
Penguin RFA measures the resonance frequency of the reusable MulTipeg TM with a non-contacting technique. The frequency is displayed as an ISQ-value (Implant Stability Quotient) from 1-99. The ISQ value correlates strongly to the micro mobility of the implant.

Just mount the MulTipeg TM, aim for the top and the ISQ value will be displayed in less than a second. Values above 70 means high stability and are typically used for one-stage and immediate loading. By taking a base line value at implant placement and another before loading, the degree of osseointegration can be measured.
REUSABLE MulTipeg TM
MulTipeg TM are:
- Available for different implant systems
- Durable, tissue-friendly
How to Use
The Penguin RFA system consists of a hand-held instrument and a reusable MulTipeg TM. A charger is delivered together with the instrument as well as a stainless steel driver for attaching the MulTipeg to the implant.
Select the correct MulTipeg for the implant being measured.
Attach the MulTipeg using the driver (approximately 6-8 Ncm of torque).
Turn on the instrument and hold the tip of the instrument close to the top of the MulTipeg.
The instrument emits a beeping sound when it starts measuring and another sound when the ISQ value is presented on the display a second later.
Penguin RFA Research Abstract
"The resonance frequency analysis (RFA) technique for implant stability measurements was developed by Meredith and co- workers more than 20 years ago. RFA makes use of a transducer (peg), which is attached to the implant and excited over a range of frequencies by electromagnetic waves to measure the resonance frequency (RF) of the transducer. The underlying RF measurements in Hz are translated to Implant Stability Quotients (ISQ) units from 1 (lowest stability) to 100 ISQ units (highest stability). A new generation of RFA technology has been developed consisting of a small pen-like battery-driven instrument (PenguinRFA) used together with reusable transducers (MulTiPeg TM). These are made from biocompatible titanium and can be autoclaved and used numerous times. The instrument can be packed in a sterile pouch and kept on the surgical tray and used by the surgeon without jeopardizing sterility. RFA measures implant stability in bend- ing as a function of interface stiffness and correlates with implant displacement, i.e. micro-mobility, under lateral loading. The ISQ value is determined by the local bone density and is influenced by implant placement technique, implant design, healing time and exposed implant height above the alveolar crest. It seems like implants with low and/or falling ISQ values pose an increased risk for failure compared with implants with high and/or increasing values. The RFA technique can be used at any stage during treatment as one additional parameter to support decision-making during implant treatment and follow-up. For instance, authors have proposed that certain levels of stability should be achieved/reached in order to commence immediate and early loading." 2
