AI/ML Overview

This document is a 510(k) Summary for the Dentis s-Clean SQ-SL Fixture, a dental implant. It does not contain information about the acceptance criteria or a study proving the device meets those criteria from an AI/algorithm performance perspective. The document focuses on establishing substantial equivalence to predicate devices through non-clinical testing.

Therefore, I cannot provide the requested information regarding AI/algorithm acceptance criteria, test set details, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, or training set details because this information is not present in the provided text.

The "Non-Clinical Test Data" section describes engineering and biocompatibility tests conducted on the device, not an AI algorithm.

Non-Clinical Test Data

Below tests were performed on subject device:

  • Fatigue Testing under the worst-case scenario according to ISO 14801:2016
    Below tests were performed for predicate devices and leveraged for the subject device:

  • Sterilization Validation Test on Fixtures according to ISO 11137-1,2,3 referenced in K192688

  • . Shelf-Life Test on Fixtures according to ASTM F1980 referenced in K153639

  • . Biocompatibility testing on fixtures according to ISO 10993-1:2009, ISO 10993-3:2014, ISO 10993-5:2009, ISO 10993-6:2007, ISO 10993-10:2010 and ISO 10993-11:2006 referenced in K153639

  • . Bacterial Endotoxin Test Report on Fixtures according to ANSI/AAMI ST72:2011, USP <161>, and USP <85> referenced in K192688

The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device.

Non-clinical test data was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments". Clinical testing was not necessary to establish substantial equivalency of the device.

The non-clinical testing results demonstrate that the subject device is substantially equivalent to the predicate device.

MR Environment Condition

Non-clinical worst-case MRI review was performed to evaluate the metallic. Dentis s-Clean SQ-SL Fixture in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry 0., Jana G. Delfino, and Sunder Rajan. 'Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795)., based on the entire system including all variations (all compatible implant bodied, dental abutments and, fixation screws) and material composition. Rationale addressed parameters per the FDA Guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.

Conclusion

Dentis s-Clean SO-SL Fixture constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, Dentis s-Clean SQ-SL Fixture and its predicates are substantially equivalent.

§ 872.3640 Endosseous dental implant.

(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
