bredent Penguin RFA
Measuring ISQ for implant stability
Enough stability for immediate restoration???
The question of whether the fitted implant is suitable for immediate restoration often represents a challenge for the treating dentist. The torque in Ncm is used as standard when inserting the implant. The bredent PenguinRFA is the ideal solution as a supplement to the ratchet.
The bredent PenguinRFA is a device used to measure the stability of implants using the resonance frequency analysis (RFA). A small, magnetic measuring pin, the MulTipegTM, is screwed into the implant or the abutment for this purpose and begins to vibrate without touching it. The value measured is shown as the “Implant Stability Quotient” (ISQ) and provides information regarding the appropriate treatment of the implant.
The measurement method
With the so-called “Driver”, the MulTipegTM is screwed into the implant or the abutment.
The MulTipegTM begins vibrating as a result of short magnetic impulses from the tip of the bredent PenguinRFA. The magnetic impulses interact with the magnets in the inside of the measuring pin.
A receiver in the bredent PenguinRFA records the magnetic alternating field of the vibrating magnets and uses this to calculate the resonance frequency and the resulting ISQ value. This value is shown on the bilateral displays after a few seconds.
The ISQ – Scala
The ISQ value of 1–99 is a measurement of the stability of the implant. The higher the value, the more stable the implant. If the value is 70 ISQ or above, immediate restoration is possible. In the event of values between 55 and 70, we recommend interlocked immediate restoration. If the value is below 55 ISQ, the implant must undergo submerged healing. The bredent PenguinRFA measures the ISQ value to an accuracy of +/- 1 ISQ unit.
The MulTipegTM is available in four different sizes and makes it possible to measure primary stability in virtually all SKY® implant system implants.
