Frequently Asked Questions

Q: What are the benefits of using MulTipegsTM?

A: MulTipegs are made from durable titanium with sealed magnets, and can be autoclaved for sterility. They are calibrated against a reference for consistent ISQ-values which in turn makes it easier to compare different implant systems. The laser marked MulTipegs are tissue friendly and leaves no foreign material inside the implants*. They are also cost effective since they are reusable.

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

A: The PenguinRFA used together with the reusable MulTipegTM, give in principle the same ISQ readings as Osstell ISQ with the disposable SmartPegs. However, MulTipegs are calibrated against a common standard which means that the ISQ values are comparable between different implants. MulTipegs must be used to get the benefits of the calibrated system.

Q: Are the reusable MulTipegsTM compatible with the disposable Osstell SmartPegs?

A: Although the two systems in principle give the same ISQ values for an implant (however see the question above about the calibration standard), they are not directly compatible. 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, this table is used instead. This is because MulTipegsTM and Smartpegs® are made from different materials (titanium vs aluminum). MulTipegs must be used to get the benefits of the calibrated system.

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

A: If a MulTipegTM is used, washed and autoclaved, it will mean some wear. Eventually, the MulTipegTM will be worn in such a way it should be replaced. How many uses that will take, differs dependent on the way it is handled, but in any case it is guaranteed for 20 autoclave cycles.

Q: What is the MulTipegTM material?

A: The reusable MulTipegTM is made in titanium, a highly biocompatible material which guarantees that no foreign material or substance comes in contact with the implant during the measurement.

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

A: If the instrument is used together with a sterile cover, it can be used 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 normally is used only for a short while at a time, it means it can be used for many sessions before recharging.

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

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

Q: Is the method documented?

A: Resonance Frequency Analysis applied on implants is documented in more than 700 peer-reviewed published articles.

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

A: The result of a measurement with the PenguinRFA instrument is presented as an ISQ-value. Internal research show that PenguinRFA together with MulTipegs produce the same results as other instruments for the measurement of ISQ.
