Intended Use

The UF(II) Implant System is indicated for surgical placement in the upper and lower jaw arches, to provide a root form means for single or multiple units' prosthetic attachment to restore a patient's chewing function. The UF(II) Implant System(Ø3.8 ~ Ø5.5) can be placed with a conventional two stage surgical process with an option for transmucosal healing or they can be placed in a single stage surgical process for immediate loading when good primary stability is achieved with appropriate occlusal loading.

Device Description

UF(II) Fixture is made of pure titanium grade 4 (ASTM F67) and the surface treatment is done with SLA (Sand-blasted, Large grit, Acid-etched). The diameters of fixture are 3.8, 4.0, 4.5, 5.0, 5.5mmand the lengths of fixture are 7.0, 8.5, 10.0, 11.5, 13.0, 15.0,16.0mm in this system. All fixture lengths are available in all diameters, except for the 7.0mm length, which is not available in 3.8 or 4.0mm diameters. The abutments and superstructures consist of Healing Abutment, Cemented Abutment Screw, Cover Screw, Solid Abutment, Cemented Cylinder, Cylinder Screw and Conical Abutment.

AI/ML Overview

The provided text describes a 510(k) summary for the UF(II) Implant System, which relies on demonstrating substantial equivalence to predicate devices rather than proving a specific performance metric against acceptance criteria in the way a clinical study for a novel device would. Therefore, much of the requested information regarding clinical study design, sample size, expert adjudication, MRMC studies, effect sizes, training sets, and ground truth establishment is not directly applicable or available in this document.

The document focuses on non-clinical testing to demonstrate that the device meets criteria of established standards and is substantially equivalent to predicate devices.

Here's an attempt to extract the closest available information based on your request, highlighting what is implicitly or explicitly stated:

1. Table of Acceptance Criteria and Reported Device Performance

The "acceptance criteria" here are meeting the criteria of the referenced standards and demonstrating substantial equivalence to predicate devices. The "reported device performance" is the outcome of non-clinical tests that conclude these criteria are met.

Differences (e.g., fixture diameter range, surface treatment for abutments) are addressed and stated not to raise new questions of substantial equivalence.

Specific Information on Study Design (Not Applicable to this 510(k) submission)

As this is a 510(k) premarket notification primarily relying on substantial equivalence through non-clinical testing, there are no clinical studies of the type you describe (e.g., involving human readers, ground truth consensus for image interpretation, effect sizes of AI assistance). The document focuses on demonstrating that the device meets established engineering and biological safety standards, and is equivalent to previously cleared devices.

Therefore, the following points are not applicable to the provided document:

  1. Sample size used for the test set and the data provenance: Not applicable, as this refers to clinical test data. Non-clinical tests would use physical samples of the device components.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for clinical assessment is not established in this type of submission.
  3. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
  4. 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: Not applicable. This device is a dental implant system, not an AI-powered diagnostic tool.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithmic device.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable, as it pertains to clinical performance assessment. Ground truth for non-clinical tests would be established through reference standards, metrology, and validated test methods.
  7. The sample size for the training set: Not applicable.
  8. How the ground truth for the training set was established: Not applicable.

Non-Clinical Test Data

The results of the non-clinical testing demonstrate that the results have met the criteria of the standards, and the subject device is substantially equivalent to the predicate device. This testing included:

Sterilization Validation and Shelf Life Testing

Sterilization validating testing has been performed in accordance with ISO 11137-1, ISO 11137-2, ISO 11137-3, ISO11737-1, and ISO 11737-2 for gamma sterilization and ISO 17665-1 and ISO 17665-2 for steam sterilization. Test results have demonstrated that the SAL of 10-6 was achieved and all testing requirements were met.

For the subject devices provided sterile, accelerated aging shelf life testing was conducted according to ASTM F1980; real time testing is being conducted to support accelerated aging results.

Fatigue Test

The fatigue test was performed on the subject device in accordance with ISO 14801:2007 Dentisty-Implants-Dynamic fatigue test for Endosseous Dental Implants. The worst case scenario was chosen based on the FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments".

The subject device was tested to evaluate its substantial equivalence according to the following standards. - Fatigue Test according to ISO 14801:2016

Biocompatibility

Biocompatibility testing was conducted according to ISO 10993-1:2009"Biological evaluation of medical devices-Part 1: Evaluation and testing within risk management process" and the biocompatibility evaluation flow chart according to the FDA Guidance document "Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices-Part 1: Evaluation and testing within a risk management process', Guidance for Industry and Food and Drug Administration Staff, Document issued on:June 16, 2016" for each of the subject devices.

§ 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.
