The KDG-Osteon Precision Milled Suprastructure is intended for attachment to a minimum of two (2) abutments.

Device Description

The purpose of this submission is for the marketing clearance for the Genesis ACTIVE Implant System which comprises endosseous root-form dental implants, mating compatible abutments, abutment screws, and other associated components for single-unit, multi-unit, and overdenture restorations.

Endosseous dental implants are surgically implanted into a patient's mouth to provide support for prosthetic devices, such as artificial teeth, in order to restore the patient's chewing function. Endosseous dental implant abutments are secured to dental implants with a retaining screw to provide support for prosthetic devices, such as artificial teeth, in order to restore the patient's chewing function. Prosthetic devices used with the dental implant abutments in this submission may be screw-retained or cement-retained.

The Genesis ACTIVE Implant System includes endosseous screw type dental implants which can be used in either single- or two-stage surgeries with associated compatible abutments, screws, and other associated accessory components. The Genesis ACTIVE Implant System includes eleven (11) compatible implant abutment designs: Healing Abutments, Straight, Angled Multi-Unit, Angled Multi-Unit, PEEK Straight Temporary, PEEK Angled Temporary, Temporary Cylinder, Titanium Temporary Immediate, Titanium Blank. There are four minor variations of the Titanium Base design: Ti-Base, ANGLEBase®, C-Base®, and ELLIPTIBase®. Prosthetic devices used with the dental implant abutments in this submission may be screw-retained or cemented.

The KDG-Osteon Precision Milled Suprastructure is an overdenture bar which is compatible with the Subject device Multi-Unit abutments. The overdenture bar is a dental restorative device that is intended for screw-retained attachment to dental abutments to aid in the treatment of partial or totally edentulous patients for the purpose of restoring their chewing function. The KDG-Osteon Precision Milled Suprastructure is fabricated by means of CAD/CAM technology by a Keystone Dental Group company and is used to facilitate the attachment of both fixed and removable prostheses.

Subject device implants are manufactured from Commercially Pure (CP) – Grade 4 titanium conforming to ISO 5832-2, Implants for surgery — Metallic materials — Part 2: Unalloyed titanium and ASTM F67, Standard Specification for Unalloyed Titanium, for Surgical Implant Applications (UNS R50250, UNS R50550, UNS R50700). They are anodized pink (AnaTite™) to provide a pink color and have the BioSpark™ surface treatment which results in a hydrophilic surface enriched with calcium and phosphorous ions.

All titanium Subject device abutments, accessories and screws are manufactured from titanium alloy conforming to ASTM F136, Standard Specification for Wrought Titanium-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R5640). Except for the Titanium Blank abutment design, all titanium Subject device abutments are anodized pink. Post surfaces of select abutments receive a media blasting treatment referred to as AnaTite™ or TiPink.

Subject device PEEK temporary abutments are fabricated from PEEK (PolyEther Ether Ketone) material.

All implants and prosthetic components are one-time use devices. All Subject device components are provided sterile and sterilized by gamma irradiation, except for Titanium Blank abutments and the KDG-Osteon Precision Milled Suprastructure which are provided non-sterile. Devices provided non-sterile or modified are sterilized by steam.

AI/ML Overview

The provided text describes the 510(k) summary for the Keystone Dental Inc. "Genesis ACTIVE Implant System." It focuses on demonstrating substantial equivalence to predicate devices through technical comparisons and non-clinical performance testing. The document explicitly states that no clinical data were included in this submission, which means there was no study proving the device meets acceptance criteria related to human performance or clinical outcomes.

Therefore, many of the requested information points, particularly those pertaining to acceptance criteria for AI performance, sample sizes for test sets in clinical studies, expert involvement in ground truth establishment for such studies, MRMC studies, and standalone performance, cannot be answered from the provided text.

The document primarily discusses bench testing and material/design comparisons to establish equivalence, rather than clinical performance acceptance criteria or studies involving human readers or AI.

Here's what can be extracted from the provided text:

1. A table of acceptance criteria and the reported device performance:

The document focuses on non-clinical performance testing (bench testing) and material/design specifications for establishing substantial equivalence, rather than specific performance metrics or acceptance criteria typically seen for AI/diagnostic devices in clinical settings. The acceptance is based on demonstrating the new device performs similarly and is as safe and effective as the predicate device through these non-clinical tests.

Acceptance Criteria Category (based on description)	Reported Device Performance/Testing Confirmation
Fatigue Testing (Mechanical)	Performed according to ISO 14801:2016 ("Dentistry – Implants – Dynamic loading test for Endosseous Dental Implants"). Worst-case scenarios were chosen based on FDA Guidance. Results "demonstrate conformance with testing requirements and support a finding of substantial equivalence."
Biocompatibility	Performed according to ISO 10993-1. Supports that the Subject device uses "nearly identical manufacturing processes to the K210117 Reference device, with slight differences in surface treatment." Biological Evaluation addressed differences with internal routine monitoring data.

Genesis ACTIVE Implant System - Abutment Types

INDICATIONS FOR USE

All digitally designed custom abutments for use with Genesis ACTIVE Implants are to be sent to a Keystone Dental validated milling center for manufacture.

EQUIVALENCE TO MARKETED DEVICE

Substantial equivalence is claimed with the Predicate devices are being used to support the expansion of technologies which differ between the Subject and Predicate devices. Provided at the end of this section is a table which compares the Indications for Use Statements and additional tables comparing the technological characteristics of the Subject, Predicate and Reference devices.

Indications for Use Statement (IFUS)

The Subject, Predicate and Reference devices have highly similar Indications for Use, differing primarily in device name and the paragraph stating that digitally designed abutments are to be sent to a Keystone Dental validated milling center for manufacture. Digitally designed abutments are included in the K22269 Reference device IFU. The Subject device Indications for Use Statement combines the relevant features of both Predicate and Reference device IFUS as the Subject device includes both traditional and digitally designed dental implant abutments. The Subject and the sponsor's K221019 Reference devices have similar wording regarding the use of the bar Suprastructure, differing only in the list of compatible implant/abutment systems. These minor differences do not raise new questions of safety or effectiveness as all the Indications for Use Statements express equivalent intended use.

{6}------------------------------------------------

Technological Characteristics

Implants

Overall, the Subject device implants are highly similar to the Predicate and Reference device device implant material and surface treatment is the same as the sponsor's Predicate device. Implant diameters and lengths are supported by the Predicate and K220200 Reference devices. The range of Subject device implant diameters are supported by the Predicate and Reference device implants are single-use, single user, the same as the Predicate device. The slight changes in implant thread design and the implant/abutment interface connection does not affect substantial equivalence nor change the intended use of the devices. Differences in the implant/abutment connections between the Subject and Reference devices do not change the intended use and have been mitigated through non-clinical bench performance testing. Sterilization and packaging of the sterile Subject device implants and screws are the K220200 Reference device. The surface treatment blast media and biocompatibility of the Subject implants is highly similar to the K210117 Reference device.

Abutments

Overall, the Subject device abutments are highly similar to the Predicate and Reference devices. Abutment designs are the same in principle, to the Predicate and Reference devices. Critical abutment dimensions, such as the Gingival Height, Prosthetic Diameter, Post Correction Angle, and Post Heights are highly similar between the Subject, Predicate and Reference device abutment designs. Subject device abutments and screws are fabricated from the same materials as the Predicate device and include the same surface treatments as Predicate and Reference devices. Sterilization and packaging of the sterile Subject device abutments and screws are the same as the Predicate device. Cleaning and sterilization of non-sterile Subject device abutments are the Sponsor's K220200 Reference device.

The Subject device PEEK material is the same as the K220200 Reference device PEEK material and is subject to the same time of use limitations. Only slight differences in gingival height, prosthetic

{7}------------------------------------------------

diameter and post height dimensions, and implant connection exist between the Predicate and K220200 Reference devices. The use of PEEK straight temporary abutments is further supported by K170131 Reference device.

Angled PEEK Temporary Abutments

The Subject device Aesthetic Angled PEEK Abutments are similar to the Predicate device angled straight Esthetic Contour Titanium Abutments but are made from PEEK. Abutments made from or that include PEEK are similar in short-term temporary usage, the same as the K220200 Reference device Temporary Immediate Abutment. The Subject device PEEK material is the same as the K220200 Reference device PEEK material and is subject to the same time of use limitations. Only slight differences in gingival height, prosthetic diameter and post height dimensions, and implant connection exist between the Predicate and K220200 Reference devices.

The 20° post correction angle and gingival heights for PEEK abutments are further supported by the K170131 Reference device which includes PEEK abutments. Prosthetic diameters are supported by the Predicate device. Slight differences in post height dimensions, and implant connection with the Predicate device do not alter the intended use of the device.

Multi-Unit Abutments

The Subject device Straight Multi-Unit Abutments are highly similar to the K22269 Reference device Straight Multi-Unit Abutments, differing only in the implant connection and anodized surface.

The Subject device 17° Angled Multi-Unit Abutments are highly similar to the K22269 Reference device 17° Angled Multi-Unit Abutments, differing only in the implant connection and anodized surface. The Subject device 30° Angled Multi-Unit Abutments are highly similar to the K22269 Reference device 30° Angled Multi-Unit Abutments, differing only in the implant connection, anodized surface, and slightly larger prosthetic diameter option. However, the slightly larger prosthetic diameter option of the Subject device 30° Angled Multi-Unit abutment is supported by the same dimension in the K222269 Reference device 17° Angled Multi-Unit abutments.

Interface copings, temporary cylinders, and healing cap accessories as part of two-part abutments are supported by the Predicate and Reference devices.

Temporary Abutments

The Subject device Titanium Temporary Abutments (engaging) are highly similar to the Predicate device and K220200 Reference device Titanium Temporary Abutments (engaging) differing only slightly in gingival height and prosthetic diameter dimensions.

The Subject device Temporary Immediate Abutments are highly similar to the K220200 Reference device Temporary Immediate Abutments, with only slight differences in available prosthetic diameters. The PEEK material is the same as the K220200 Reference device with the same intended period of use.

Titanium Base Abutments

The Subject device titanium base abutments are two-piece abutments composed of a stock titanium base cemented to a zirconia top-half. The zirconia conforms to ISO 13356 and the cement used was cleared under K130436. The final patient-matched zirconia component is manufactured by a Keystone Dental validated milling center. These abutments are compared to the K222269 Reference device titanium base abutments (Ti-Base, C-Base®, ANGLEBase®, ELLPTIBase®) differing only slightly in available Gingival Height and Prosthetic Diameter configurations and implant connection, as well as angulation of the patient-matched zirconia component. The difference in manufacturing and angulation is addressed by non-clinical bench testing.

{8}------------------------------------------------

Titanium Blank Abutments

The Subject device titanium blank abutments are highly similar in design to the K22269 Reference device titanium blank abutments differing only slightly in available Gingival Height, Diameter, Post correction angle dimensions and implant connection.

Abutment Retention Screws

The Subject device abutment retention screws are fabricated from the same material as the Predicate device. Any differences in surface treatments between the Subject device and Reference device screws were mitigated through non-clinical performance testing of the Subject device.

The table below presents the design specifications for the two categories of suprastructures:

Packaging and sterilization of the KDG-Osteon Precision Milled Suprastructure is the K221019 Reference devices.

NON-CLINICAL PERFORMANCE TEST DATA

Fatigue testing was performed according to the requirements of ISO 14801:2016, Dentistry – Implants – Dynamic loading test for Endosseous Dental Implants. The worst-case scenarios were chosen based on the FDA Guidance, Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments.

The Subject devices have the same nature of body contact, contact duration, material formulation and sterilization methods compared to the sponsor's Predicate and Reference devices.

{9}------------------------------------------------

Biological Evaluation of the Subject device was performed according to ISO 10993-1. This evaluation supports the Subject device utilizes nearly identical manufacturing processes to the K210117 Reference device, with slight differences in surface treatment. The difference in surface treatment is addressed within the Biological Evaluation, including evaluation of internal routine monitoring data related to the implant's modified surface treatment and manufacturing cleaning processes of the Subject device.

ISO 10993-5 Cytotoxicity testing on the Subject device or suitable test specimens was performed to support suitable biocompatibility of the Subject device.

Endotoxin testing on the Subject device or suitable test specimens was performed following USP<85> according to the sponsor's endotoxin sampling plan.

Validations were performed on the Subject device or suitable test specimens according to ISO 11137-1:2019, ISO 11137-2:2015 and ISO/TS 13004:2013 to demonstrate suitable sterilization of the Subject device sterile components.

Steam sterilization validations according to ISO 17665-1:2009 for non-sterile and modified components were leveraged from the sponsor's K220200 Reference device.

The results of the non-clinical testing demonstrate conformance with testing requirements and support a finding of substantial equivalence.

Non-clinical worst-case MRI review was performed to evaluate the Subject device components in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., 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 bodies, abutments, 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.

No clinical data were included in this submission.

CONCLUSION

Overall, minor differences in the designs, implant connections, or sizes between the Subject device, the Predicate device, and the Reference devices do not affect substantial equivalence.

lmplant designs are supported by the similar Predicate device. Implant abutment designs are supported by similar Predicate and Reference devices.

Regulation Number and Section

§ 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.
