Device Description

MT-Bone is a piezoelectric ultrasonic device designed for oral bone surgery.
MT-Bone uses piezoelectric ultrasound technology to generate mechanical micro vibrations that can cut, drill or abrade through mineralized structures using appropriate inserts.
This allows an efficient and safe action which preserves the integrity of the osteotomized surfaces.
The micrometric, ultrasonic vibrations of the inserts provide greater precision and a selective action compared to traditional methods such as drills or oscillating saws (which act with macro vibrations), therefore minimizing traumatic effect on soft tissues. Depending by the Indication for use a lot of different type of inserts are available in Mectron portfolio.

AI/ML Overview

The provided text describes the MT-Bone device and its substantial equivalence to a predicate device (PIEZOSURGERY TOUCH, K122322). However, it does not contain specific acceptance criteria, reported device performance metrics in a table, or details of a study proving the device meets said criteria in the way typically found for AI/ML-based medical devices.

The document primarily focuses on demonstrating substantial equivalence through a comparison of technological characteristics, indications for use, and general safety/performance testing. There is no mention of an algorithm, AI, or machine learning in the context of device function.

Therefore, many of the requested items (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC study, standalone performance, training set size) are not applicable or cannot be extracted from this document, as they pertain to a different type of device or evaluation method.

Here's a breakdown of what can be extracted based on the provided text, and where information is missing or not applicable:

1. Table of acceptance criteria and the reported device performance:

The document states that a series of non-clinical bench performance tests were conducted to evaluate the efficacy and safety of the device. The "acceptance criteria" are implied by the statement "All tests passed successfully" or "The testing showed that..." without quantitative metrics.

Bench performance testing categoryImplied Acceptance Criteria (Pass/Fail)Reported Device Performance
Electrical safetyComplies with IEC 60601-1Considered electrically safe.
EMCComplies with IEC 60601-1-2Demonstrated electromagnetic compatibility.
BiocompatibilityComplies with ISO 10993-1 and FDA guidanceRelevant parts are biocompatible.
ReprocessingEfficacy of cleaning and sterilization processesEfficacy shown for relevant parts.
Software and FirmwareComplies with IEC 62304+A1, FDA guidanceDeveloped and positively validated.
Performance Testing – Bench (Boosted PIEZOSURGERY Inserts)Improved performance, amplitude/frequency requirements, reduced time vs. predicateConfirmed improved performance, met amplitude/frequency, reduced time.
Performance Testing – Bench (PIEZODRILL Inserts)Intra osseous temperature, soft tissue safety, amplitude/frequency requirements, reduced time vs. predicateMet requirements on intra osseous temperature, soft tissue safety, amplitude/frequency, reduced time.
Usability TestingSatisfactory installation, configuration, assembly, GUI understanding, clinical procedure evaluation, positive KOL feedbackPassed successfully, usability validated, increased performance perceived by KOLs.
Cadaver LabPerformance, safety, benefits, usability, equivalence to predicate, compliance to GSPRRequirements confirmed, equivalence to predicate demonstrated, compliance to GSPR.
Distribution testingTransport simulation (ASTM D4169), sterile barrier maintenance, electrical safety after transportPassed all tests, packaging compliant, all items worked properly.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

  • Sample Size for Test Set: Not specified for any of the non-clinical tests. For the cadaver lab, it refers to "clinicians" but no number of cadavers or specific cases is given.
  • Data Provenance: Not explicitly stated for any of the tests. It's internal testing by the manufacturer (Mectron S.p.A., Italy).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

  • Number of Experts: For Usability Testing, it mentions "KOLs feedback and evaluations" (Key Opinion Leaders) but does not specify the number or their qualifications. For the Cadaver Lab, it states "clinicians" but again, no number or qualifications are provided.
  • Qualifications of Experts: Not specified.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

  • Not applicable as the tests described are primarily bench, software, and usability/cadaver lab evaluations, not diagnostic accuracy studies requiring adjudication of ground truth by multiple experts.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

  • No, a multi-reader multi-case (MRMC) comparative effectiveness study was not performed. The device described is a surgical instrument (piezoelectric ultrasonic device), not an imaging or diagnostic AI/ML device that assists human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

  • Not applicable. The device is a surgical instrument requiring human operation. There is no mention of a standalone algorithm component that performs autonomously.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

  • For the non-clinical bench tests, "ground truth" is typically defined by engineering specifications, regulatory standards (e.g., IEC, ISO), and performance targets for the device's physical functions (e.g., amplitude, frequency, temperature, cutting efficacy).
  • For Usability and Cadaver Lab tests, the "ground truth" or validation came from "KOLs feedback and evaluations" and "evaluation process conducted by clinicians," implying expert assessment of performance, safety, benefits, and usability.

8. The sample size for the training set:

  • Not applicable. The document does not describe an AI/ML device that requires a training set.

9. How the ground truth for the training set was established:

  • Not applicable. The document does not describe an AI/ML device that requires a training set.

Substantial Equivalence Discussion

The proposed device and the predicate device PIEZOSURGERY TOUCH (K122322 cleared on 12/06/2012) have the intended use substantially identical.

The proposed device and the predicate device share also many identical features, including identical/equivalent principle of operation and technological characteristics.

The differences identified in the above table 1.1 clearly have no impact on safety or effectiveness of the device. Any differences identified in above table does not introduce any new questions regarding safety and effectiveness.

These considerations are also confirmed by the performance test carried out in comparison with the predicate device PD1.

The data presented in this submission demonstrates the identities existing between the MT-Bone device and the predicate device, and thus support a finding of substantial equivalence between the subject device and the referenced predicated device, already in commercial distribution in the United States.

Performance Testing –BenchA series of tests evaluated the efficacy and safety of reusable inserts, providingvaluable insights into their performance and ensuring the highest standards ofquality and patient well-being.
For boosted PIEZOSURGERY inserts the pre-clinical tests confirmed:
The improvement of performance with respect to PIEZOSURGERY touch; The requirements on amplitude and frequency; The reduced time to complete the procedures with respect to PIEZOSURGERY touch.
For PIEZODRILL inserts:
The requirements on intra osseous temperature; The requirements on soft tissue safety; The requirements on amplitude and frequency; The reduced time to complete the procedure with respect to PIEZOSURGERY touch.
Usability TestingThe usability tests included:
- simulation of the installation, configuration and assembly of the device inaccordance with the user manual.
- Understanding of the graphical interface relating to functional screens andsupport screens.
- clinical procedures evaluation on implant site preparation, osteotomy andosteoplasty.
The usability tests passed successfully. Analyzing all the KOLs feedback andevaluations, the usability of the device, considering in particular all the newaspects (GUI, PIEZOSURGERY MT and PIEZODRILL MT handpieces, K11torque wrench, PD inserts) results validated according to the test objectives.
Furthermore, the validation in terms of clinical procedures highlights a wellperceived increase of the performance of the most representative inserts used forosteotomy, osteoplasty and pilot hole preparation.
Cadaver LabThe cadaver lab confirmed the requirements on performance, safety, benefits andusability. The evaluation process conducted by clinicians in the cadaver lab hasbeen comparative between the new device MT-Bone and its predicatePIEZOSURGERY touch.
By comparing the MT-Bone system with the predicate device, clinicians haveassessed its improvements, advantages, or potential limitations in clinicalapplications for which it is intended.
This comparative analysis has also collected data to demonstrate the equivalenceof the MT-Bone device to its predicate legacy PIEZOSURGERY touch device andthe compliance to the relevant general safety and performance requirements.
Distribution testingTransport simulation (according to ASTM D4169), verification of the sterile barriermaintenance of the single use components and electrical safety verification on thedevice after transport simulation were done on the device system configuration.
The verification of the sterile barrier maintenance of the single use componentspassed all the performed tests.
All the controls on the components after the tests performed in externallaboratories were conducted and all the items worked properly.
Electrical safety tests, done internally by V&V department, resultedin
