Tellos ISQ Buddy is indicated for use in measuring the stability of dental implants in the maxillofacial region.
Device Description
The Tellos ISQ Buddy measurement system consists of: Tellos ISQ Buddy Instrument (Hand-held instrument), ISQ Peg Driver (Driver to attach the ISQ peg to the implant), Tellos ISQ Buddy Charger (100-240 VAC to 5VDC charger for the instrument batteries), and ISQ Peg (Measurement pin to attach to the implant. Different pins are available to fit different implant types.). The instrument is a hand-held, battery-driven device for measuring the relative stability of a dental implant. A small pin "ISQ peg" is attached to the dental implant by a screw-connection, with the Peg Driver. The pin has a small magnet incorporated into its top. The instrument is held towards the ISQ Peg, and sends short magnetic pulses that bring the pin into vibration. After a pulse has been sent, the instrument measures the vibration by sampling the signal from the alternating magnetic field that follows from the vibrating pin. The frequency of the signal is determined by the instrument and is presented as an "ISQvalue", 1 to 100, where a higher number means higher stability. The measurement takes about 1 second. The instrument consists of a microcontroller and circuits to send the magnetic pulses, to receive the measurement signal, and to present the measurement value. A circuit for battery-charging is also included. Two 2-digit LED displays, one on each side of the instrument, show the measurement value and also communicate possible error codes and software id number at start-up. One operating key is used to turn the instrument on and off. The electronics are contained in a plastic body, which is sealed except for the instrument which has a charging connector. The plastic body is made from PC/ABS plastic except for the tip, which is made from PEEK. No part of the instrument is intended to contact the patient; however there can be unintentional contact with the tip of the instrument. The instrument is battery-driven and contains re-chargeable NiMh-batteries can be charged during use, but it should not be attached while measuring due to the risk of power line interference making it impossible to measure. For safety, a charger complying with IEC 60601-1 is used. The charger connector is of a type that does not allow other chargers to be connected, thereby eliminating the risk of the wrong charger being used.
More Information

Not Found

No
The device description details a system based on magnetic pulses and vibration measurement, processed by a microcontroller to determine a frequency and convert it to an ISQ value. There is no mention of AI or ML algorithms, training data, or complex pattern recognition beyond basic signal processing.

No.
The device is indicated for measuring the stability of dental implants, which is a diagnostic function, not a therapeutic one. It provides information but does not actively treat or modify a physiological function.

Yes

Explanation: The device is indicated for "measuring the stability of dental implants" and provides an "ISQvalue" to quantify this stability. This measurement provides information about the condition of the implant, which can be used to inform clinical decisions, aligning with the definition of a diagnostic device.

No

The device description clearly outlines multiple hardware components including a hand-held instrument, peg driver, charger, and ISQ peg, in addition to the software.

Based on the provided information, the Tellos ISQ Buddy is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This typically involves testing blood, urine, tissue, or other bodily fluids or samples.
  • Tellos ISQ Buddy Function: The Tellos ISQ Buddy measures the mechanical stability of a dental implant within the patient's bone. It does this by inducing and measuring vibrations in a peg attached to the implant. It does not analyze any biological specimens from the patient.
  • Intended Use: The intended use is to measure the stability of dental implants, which is a physical characteristic, not a biological or chemical property of a specimen.

Therefore, the Tellos ISQ Buddy falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol

The Tellos ISQ Buddy instrument brings a pin attached to a dental implant into vibration and then measures the resonance frequency of the vibrating pin. The resonance frequency is then presented as an "ISQ-value" 1-100. The predicate device does the same, with the same technological principle. The technical differences concerning the measurements are the electronics and the software since other circuits are used. To make sure the instrument present the same values as the predicate device, a comparison was made with an artificial frequency signal which was varied from 1,000 to 10,200 Hz with a resolution of 100 Hz. The accepted deviation was +/-1 ISQ throughout the scale 1-100 ISQ. A comparison was also made by measuring on an Osstell SmartPeg attached to an implant embedded in artificial bone. The stability of the implant could be altered by compressing the bone with a varying force. The stability was here varied from 3 to 85 ISQ and the acceptance criteria were +/- 1 ISQ.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Comparison test with an artificial frequency signal: varied from 1,000 to 10,200 Hz with a resolution of 100 Hz. Accepted deviation: +/-1 ISQ. Result: deviation 0 ISQ compared to predicate device.
Comparison test with Osstell SmartPeg attached to an implant embedded in artificial bone: stability varied from 3 to 85 ISQ. Acceptance criteria: +/- 1 ISQ. Result: deviation 0 ISQ compared to predicate device.
The Tellos Buddy instrument has been tested according to, and found to comply with the following:

  • EMC standard IEC 60601-1-2
  • Software validation according to FDA guidance for Software Contained in a Medical Device
  • Sterilization validation according to ISO 17665-1 and ISO 17665-2
  • Biocompatibility standard ISO 10993-1
    The conclusion from the tests is that Tellos ISQ Buddy produces the same output data as the predicate device in the same measurement situation.

Tellos ISQ Buddy Charger

1.4.2 Basic principle and functionality

The Tellos ISQ Buddy instrument is a hand-held, battery-driven device for measuring the relative stability of a dental implant.

A small pin "ISQ peg" is attached to the dental implant by a screw-connection, with the Peg Driver. The pin has a small magnet incorporated into its top. The instrument is held towards the ISQ Peg, and sends short magnetic pulses that bring the pin into vibration. After a pulse has been sent, the instrument measures the vibration by sampling the signal from the alternating magnetic field that follows from the vibrating pin. The frequency of the signal is determined by the instrument and is presented as an "ISQvalue", 1 to 100, where a higher number means higher stability. The measurement takes about 1 second.

Instrument tip held towards an ISQ Peg

1.4.3 Technical details

The instrument consists of a microcontroller and circuits to send the magnetic pulses, to receive the measurement signal, and to present the measurement value. A circuit for battery-charging is also included. Two 2-digit LED displays, one on each side of the instrument, show the measurement value and also communicate possible error codes and software id number at start-up. One operating key is used to turn the instrument on and off.

The electronics are contained in a plastic body, which is sealed except for the instrument which has a charging connector. The plastic body is made from PC/ABS plastic except for the tip, which is made from PEEK. No part of the instrument is intended to contact the patient; however there can be unintentional contact with the tip of the instrument.

The instrument is battery-driven and contains re-chargeable NiMh-batteries can be charged during use, but it should not be attached while measuring due to the risk of power line interference making it impossible to measure. For safety, a charger complying with IEC 60601-1 is used. The charger connector is of a type that does not allow other chargers to be connected, thereby eliminating the risk of the wrong charger being used.

1.4.4 Materials used

Instrument body: PC/ABS Instrument tip: PEEK (USP VI) Instrument seal: Silicone (USP VI) Instrument key: Silicone (USP VI) ISQ Peg Driver: Stainless steel, ASTM F899 ISQ Peg: Titanium grade 5, ASTM F136

1.5 Indications for Use

Tellos ISQ Buddy is indicated for use in measuring the stability of dental implants in the oral cavity and the maxillofacial region.

1.6 Comparison and differences to the Predicate Device

The instrument functions the same way as the predicate device regarding the measurement principle and technology used. The differences are in the handling; Tellos ISQ Buddy is a hand-held instrument while the predicate device consists of two parts; the instrument and the measurement probe.

Tellos ISQ Buddy has no memory to store the measurement values; the predicate device has a memory that stores the measurements. The predicate device also has an inbuilt clock timer, and a computer connection for transferring measurement values. Tellos ISQ Buddy has no timer or computer connection. The lack of these features (memory, timer, data transfer) is not considered to be an inconvenience for the user. Instead, it decreases the risk of mixing up values with each other.

1.7 Performance testing

The Tellos ISQ Buddy instrument brings a pin attached to a dental implant into vibration and then measures the resonance frequency of the vibrating pin. The resonance frequency is then presented as an "ISQ-value" 1-100. The predicate device does the same, with the same technological principle. The technical differences concerning the measurements are the electronics and the software since other circuits are used. To make sure the instrument present the same values as the predicate device, a comparison was made with an artificial frequency signal which was varied from 1,000 to 10,200 Hz with a resolution of 100 Hz. The accepted deviation was +/-1 ISQ throughout the scale 1-100 ISQ.

A comparison was also made by measuring on an Osstell SmartPeg attached to an implant embedded in artificial bone. The stability of the implant could be altered by compressing the bone with a varying force. The stability was here varied from 3 to 85 ISQ and the acceptance criteria were +/- 1 ISQ.

Both tests produced ISQ values that were exactly the same (deviation 0 ISQ) for both instruments.

The Tellos Buddy instrument has been tested according to, and found to comply with the following:

  • . EMC standard IEC 60601-1-2
  • Software validation according to FDA guidance for Software Contained in a Medical Device ●
  • . Sterilization validation according to ISO 17665-1 and ISO 17665-2
  • Biocompatibility standard ISO 10993-1

1.8 Test conclusions

The conclusion from the tests is that Tellos ISQ Buddy produces the same output data as the predicate device in the same measurement situation.

1.9 Substantial Equivalence Conclusion

The purpose of using the instrument is to measure the ISQ-value (the relative stability) of the implant. Tellos ISQ Buddy has the same indications for use, measurement output and technology as the predicate device. The differences in the memory, clock, display and materials used do not change the intended use nor do they affect the safety and effectiveness as compared to the predicate device cleared in K082523.

The device description, software validation, performance testing, sterilization and biocompatibility assessment demonstrate the substantial equivalence of the submission device to the identified predicate device.

Therefore, the Tellos ISQ Buddy can be found substantially equivalent to the Osstell ISQ cleared in K082523.
