The screws are intended to provide fixed anchorage for attachment of orthodontic appliances intended to facilitate the orthodontic movement of teeth. They are used temporarily and are intended to be removed after orthodontic treatment has been completed. The screws are intended for single use only.
The Syntec Orthodontic Mini Screw Extended System is a modification of our own device Syntec Orthodontic Mini Screw (K090476). The screws are fabricated from stainless steel (SUS316L) per ISO 5832-1:2007/ASTM F138-13 and Titanium-6 Aluminum-4 Vanadium Eli (Extra Low Interstitial) Alloy per ISO 5832-3:1996/ASTM F136-13 as same as previous devices (K090476). The modifications included in the subject submission are a change to the screw hole type, from the previously cleared circular design, to a rectangular shape.
The provided text does not contain information about an AI/ML-based medical device. Instead, it describes a traditional medical device, the "Syntec Orthodontic Mini Screw Extended System," and its 510(k) premarket notification to the FDA.
Therefore, I cannot provide the requested information about acceptance criteria, study details, ground truth establishment, or human-in-the-loop performance studies, as these concepts are typically applied to AI/ML device evaluations and are not present in this document.
The document primarily focuses on demonstrating substantial equivalence of the new orthodontic mini screw system to a previously cleared predicate device, based on material composition, dimensions, and manufacturing processes, with a minor modification in screw hole shape. The performance data section refers to non-clinical tests (dimensional, material mechanical property standards, biocompatibility, fracture load, rotational fracture torque, and axial pull-out strength), stating these tests were leveraged from the predicate device and not repeated for the new submission.
§ 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.
