The Stern Micro ERA System is a resilient retention device for dental prosthesis, designed to be used in restoration of removable dentures.
Device consists of a series of nylon male attachments in six variable sizes to provide six levels of retention. The six levels of retention are color coded - white, orange, blue, gray, yellow, and red (in order of increasing degrees of retention). Variations in the degree of retention are incorporated to facilitate requirements of individual patients. It also includes a black processing (also referred to as fabricating) male that is not used in the mouth for retention of the finished denture, but only used as a tool to incorporate the final snap-in male into the finished dental appliance. A resin female is also incorporated in this system, along with stainless steel and titanium alloy instruments.
The provided document is a 510(k) summary for the Stern Micro ERA Attachment System, a dental device. It does not contain information about acceptance criteria or a study proving that the device meets such criteria.
Instead, this document is a regulatory submission for premarket notification, demonstrating substantial equivalence to a predicate device. It explicitly states: "This submission is a Special 510(k): Abbreviated 510(k) as described in FDA's guidance document entitled 'The New 510(k) Paradigm - Alternate Approaches to Demonstrating Substantial Equivalence in Premarket Notifications.' In support of this 510(k), Sterngold has provided information to demonstrate conformity with FDA's guidance document entitled Premarket Notification 510(k): Regulatory Requirements for Medical Devices."
The conclusion further clarifies: "Based on the indications for use, technological characteristics, and comparison to predicate devices, the Stern Micro ERA System has been shown to be safe and effective for its intended use."
Therefore, I cannot provide the requested information. The document focuses on demonstrating substantial equivalence to a previously approved device (Stern ERA System – 510(k) No. K 913348) rather than presenting a performance study against specific acceptance criteria.
§ 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;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
