FDA 510(k) Search - By Innolitics (SaMD and AI Experts)

The SP 4055 and SP 4055 LUX modules are sub-assemblies of the SUPPRASON P5 Booster Piezoelectric Ultrasonic Scaling Generator which received 510(k) clearance for dental applications (K961158) on May 23, 1996. The SP 4055 and SP 4055 LUX Modules maintain all the functions and the main components of the SUPRASSON P5 Booster, but are stand-alone sub-assemblies manufactured by SATELEC, all with the same components and materials used in the manufacture of the original SUPRASSON P5 Booster product, which can be used in standard dental units. The intended use, technical performance, and clinical indications are identical to those of their predicate device, the SUPRASSON P5 Booster (K961158).

The SP 4055 and SP 4055 LUX modules are multi-purpose ultrasonic generators to be marketed as modular sub-assemblies to manufacturers of dental units. Each module is shipped with three standard tips, 1, 2, and 10P. The SP 4055 and SP 4055 LUX are comprised of 3 setting ranges:

scaling, prosthesis removal, amalgam plugging,
ultrasonic endodontic treatment, and
ultrasonic periodontal treatment.

As the ultrasonic waves are produced by piezoelectricity, the SP 4055 and SP 4055 LUX module handpieces give off very little heat, making it possible for surgeons to perform both periodontal work (subgingival work at low power, where the absence of overheating is vital), as well as loosening (requiring high power, but without the unpleasant side-effect of a hot handpiece).

With the activation of a simple spray, the system ensures efficient cavitation and maximum operating power.

The electronics automatic control system has the capability to adjust power instantaneously in function of the resistance encountered by the insert, and varies handpiece and tips frequency so as to optimize power output.

The SP 4055 and SP 4055 LUX Modules, similar to their predicate device, SUPRASSON P5 Booster (K961158), operate from the action of cavitation, following the propagation of ultrasounds in a frequency spectrum comprised between 27 and 35 kHz.

AI/ML Overview

The provided document is a 510(k) summary for the SATELEC SP 4055 and SP 4055 LUX Modules, which are piezoelectric ultrasonic scaling generators. These modules are largely identical to their predicate device, the SUPRASSON P5 Booster (K961158).

The acceptance criteria for this device are based on demonstrating substantial equivalence to the predicate device. The study proving the device meets these criteria is a substantial equivalence comparison. This type of submission relies on showing that the new device has the same intended use, similar technological characteristics, and raises no new questions of safety and effectiveness as a legally marketed predicate device.

Here's the breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Implicit from Substantial Equivalence)	Reported Device Performance
Intended Use: Prophylaxis, preservation of soft and hard tissue during dental treatments (scaling, periodontics, endodontics).	Identical to predicate device (SUPPRASON P5 Booster, K961158).
Technical Performance: Production of ultrasonic waves via piezoelectricity, operating in a frequency spectrum between 27 and 35 kHz, automatic power adjustment, low heat generation.	Technical characteristics are "almost identical" to the predicate (Satelec SUPRASSON P-5 Booster). Operates from cavitation following ultrasound propagation in 27-35 kHz range. Low heat, efficient cavitation, maximum power, automatic electronic control for instantaneous power adjustment.
Safety and Effectiveness: Should not raise new questions of safety or effectiveness compared to the predicate device.	Differences in technical specifications, materials, physical appearance, and control systems "do not affect the relative safety or effectiveness" compared to the predicate.
Materials: Same components and materials as the predicate device.	Manufactured with "the same components and materials used in the manufacture of the original SUPPRASON P5 Booster product."
Clinical Indications: Identical to the predicate device.	Identical to the predicate device. Explicitly lists: Scaling (interdental junction, tooth neck, subgingival, large deposits, coatings/tobacco stains, periodontal pockets, interproximal, retro surgery, amalgam plugging, prosthesis loosening, inlay/onlay condensation); Endodontia (canal preparation, cleaning, filling, treatment resumption, prosthesis, micro retro surgery, gutta condensation); Periodontia (root planing, initial therapy, periodontal pockets, furcations, maintenance therapy).

2. Sample Size Used for the Test Set and Data Provenance

This is not a clinical study in the traditional sense with a "test set" of patients. Instead, it's a device comparison and review of technical specifications. The "test" set essentially refers to the detailed comparison of the new device's specifications and performance against the predicate device's established specifications and performance.

Sample Size: Not applicable in the context of a patient-based test set. The "sample" here would be the physical devices themselves (SP 4055 and SP 4055 LUX Modules) and their technical documentation, compared against the predicate device's documentation and specifications.
Data Provenance: The information is derived from internal design documents, technical specifications, and potentially bench testing data from SATELEC (based in France: Z.I. du Phare, BP 216 Avenue Gustave Eiffel 33708 Merignac Cedex FRANCE). This would be prospective in the sense that the new device was designed and evaluated against existing predicate device data to support the 510(k) submission.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Number of Experts: Not specified. For a 510(k) submission of this type, the "experts" are typically the manufacturing engineers, quality control personnel, and regulatory affairs specialists at SATELEC who compiled the technical specifications and conducted any necessary bench testing. The FDA review team (Office of Device Evaluation, Division of Dental, Infection Control and General Hospital Devices) acts as the ultimate "expert" body in determining substantial equivalence.
Qualifications: For SATELEC, these would be engineers and regulatory professionals. For the FDA, it would be medical device reviewers and scientific staff with expertise in dental devices, as indicated by the "Director Division of Dental, Infection Control and General Hospital Devices" signature.

4. Adjudication Method for the Test Set

Not applicable. There is no independent adjudication of a "test set" in the way one would for clinical image interpretation. The substantial equivalence determination is made by the FDA based on the provided data and comparison to the predicate device.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No, an MRMC comparative effectiveness study was not done. This type of study is typically used for diagnostic devices involving human interpretation of clinical data (e.g., radiologists reading images), not for a device like an ultrasonic scaler where direct performance metrics and physical characteristics are compared.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done

Yes, a form of "standalone" evaluation was done implicitly. The device (algorithm/machine) performance is based on its physical and functional characteristics (frequency range, power output control, heat generation, cavitation) as an independent unit, without requiring human-in-the-loop performance for its core function or for the substantial equivalence claim. The device itself is a standalone unit (though as a sub-assembly for dental units).

7. The Type of Ground Truth Used

The "ground truth" for this substantial equivalence determination is the established safety and effectiveness of the legally marketed predicate device (SUPRASSON P5 Booster, K961158). The new devices (SP 4055 and SP 4055 LUX Modules) are compared against the known characteristics and performance of this predicate.

8. The Sample Size for the Training Set

Not applicable. This is not a machine learning or AI-based device that requires a "training set" of data.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as no training set was used.
