Frequently Asked Questions

Q: What are the benefits of using MulTipegs™?

A: MulTipegs are made from durable titanium with sealed magnets, are re-usable and can be autoclaved for sterility. They are calibrated against a reference to ensure consistent ISQ values, making it easier to compare different implant systems. The laser-marked MulTipegs are tissue-friendly.

Q: Does the PenguinRFA produce the same ISQ values as the Osstell ISQ?

A: PenguinRFA used together with the reusable MulTipeg™ gives essentially the same ISQ readings as Osstell ISQ used with disposable SmartPegs. However, MulTipegs are calibrated against a reference to ensure consistent ISQ values between different implants. MulTipegs must be used to get the benefits of the calibrated system.

Q: Are the reusable MulTipegs™ compatible with the disposable Osstell SmartPegs?

A: Although in principle the two systems give the same ISQ values for an implant (however, see the question above about the calibration standard), they are not directly exchangeable. If PenguinRFA is used with Osstell Smartpegs, the measurements need to be adjusted according to this table. If an Osstell instrument is used with MulTipegs, use this table instead. This is because MulTipegs™ and Smartpegs® are made from different materials (titanium vs. aluminium). MulTipegs must be used to get the benefits of the calibrated PenguinRFA system.

Q: How many times can I use the reusable MulTipegTM ?

A: Using, washing and autoclaving a MulTipeg™ leads to some wear, and eventually it will need to be replaced. How many uses that will take differs depending on the way it is handled, but the MulTipegTM is validated for 20 autoclave cycles.

Q: What is the MulTipeg™ material?

A: The reusable MulTipeg™ is made of titanium, a highly biocompatible material.

Q: How do I work with the system under sterile conditions?

A: Use a sterile cover with the instrument for use in a sterile environment. Both the MulTipeg and the MulTiPeg Driver are autoclavable.

Q: How long before the batteries have to be recharged?

A: Fully charged batteries will provide more than one hour of continuous measurements. Since the instrument is normally only used for short periods of time, it can be used for many sessions before recharging.

Q: What cut-off ISQ value should I strive for?

A: The ISQ value requirement differs depending on the surgical protocol (one or two-stage), loading protocol (immediate, early, standard, prolonged) and clinical situation (single tooth, full bridge). More information about how to use the ISQ value can be found here.

Q: Is the method documented?

A: Resonance Frequency Analysis of implants is documented in more than 1000 peer-reviewed published articles.

Q: Is the published Resonance Frequency Analysis (RFA) documentation valid for PenguinRFA?

A: The results of a measurement with the PenguinRFA instrument are presented as an ISQ value. Internal research shows that the PenguinRFA together with MulTipegs produce the same results as other instruments for measuring ISQ.

Q: How many measurement directions do you recommend?

A: We are recommending measuring from at least two directions (perpendicular to each other), to pick up the highest and the lowest ISQ. For more information, see the manual.

Q: How do you reduce electromagnetic interference to reduce error readings?

A. Try to distance any other electronic equipment from the tip of the instrument. You can use the PenguinRFA as an “interference detector” by moving it close to other equipment and check if the Electromagnetic noise warning (display flashing, instrument making noise continuously) is occurring. For more information, see the manual.

Q: How do you interpret a low ISQ in one direction?

A:If the ISQ is lower in one of the two directions, the implant stability is most likely lower there. More information about the difference when measuring from different directions can be found in the article: Sennerby L, Meredith, Periodontology 2000, Vol. 47, 2008, 51–66
