Here you will find all the information you need about your instrument.
Measure at implant placement and again before the final restoration to monitor the development of osseointegration. If the ISQ value is not high enough it is advised to add time and remeasure before proceeding with the prosthetic rehabilitation of the implant.
The SmartPeg measures the stability in all directions and singles out the most stable and the least stable direction. Sometimes, there is no difference between them. To make sure to measure both values, the probe should be held perpendicular to the jaw line for one measurement, and in line with the jaw line for the other measurement. The two ISQ’s represent these values. If the instrument finds them both at the same time, and they differ more than 3 ISQ units, they are presented on the display together.
Press any button for 2 seconds to start the instrument.
Finger-tighten the SmartPeg into the implant (or abutment) with the SmartPeg Mount (4-6 Ncm)
Aim with the probe towards the magnet on top of the SmartPeg.
When in the right range the instrument will emit three beeps and the ISQ value will be shown on the display.
Take two measurements, 90 degrees perpendicular to each other, to get the highest and the lowest stability value.
Normally the ISQ-values are in the same range but if one is very low it is advised to use a more conservative treatment protocol.
It is required to take two measurements; first at implant placement and a second measurement before the final restoration, to monitor the osseointegration. A low or a decreasing ISQ-value should be considered a warning.
The SmartPegs are single use items. To avoid damage to the implant, the SmartPeg material is quite soft, which limits the lifetime of the threads. So the SmartPeg cannot be reused for two reasons:
First, the magnet cannot stand the heat of an autoclave, it will be affected and discolored. Second, the threads are made weak not to jeopardize the inner threads in the implant. Reusing the SmartPeg might wear out the threads and give misleading ISQ values.
The SmartPeg should be tightened with 4-5 Ncm, which means “finger tight”, using the SmartPeg Mount. It is enough with firm contact between the SmartPeg and the implant. The difference in ISQ value will then stay within 2 ISQ units. (If the SmartPeg is tightened too loosely, the ISQ-value will be lower.) If the SmartPeg is over-tightened, there is a risk that the SmartPeg threads will be damaged.
Can be cleaned using a damp cloth with water or isopropyl alcohol solution. Do not immerse the ISQ instrument in water, or clean under running water.
Single use only.
Must be autoclaved according to the recommended sterilization method, validated to sterility assurance levels (SAL), according to ISO 17665-1 and ISO 17664. Other sterilization cycles may also be suitable, although individual clinicians or hospitals are advised to validate other methods before use. The Probe and SmartPeg Mount should be placed in suitable packaging for the sterilization process.
When storing the probe, don’t twist, kink or coil the cable too tightly.
