Intended Use

Preat Abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for single-unit or multi-unit prosthetic restorations. The Titanium Base abutments consists of two major parts. Specifically, the titanium base and the mesostructured components make up a two-piece abutment. All digitally designed custom abutments, superstructures, and/or hybrid crowns for use with Titanium Bases or Titanium Blanks are to be sent to a Preat validated milling center for manufacture.

Device Story

Preat Abutments are dental implant abutment systems used to support prosthetic restorations (single or multi-unit). The system includes temporary abutments, multi-unit straight/angled (17°, 30°) abutments, titanium base abutments (engaging/non-engaging), titanium blanks, and healing abutments. The titanium base abutment is a two-piece design consisting of a titanium base and a CAD/CAM zirconia superstructure. Digitally designed custom abutments/superstructures are manufactured at a Preat-validated milling center. The device is used by dental clinicians in a clinical setting. The abutments connect to compatible OEM implant systems (Astra Tech OsseoSpeed EV, Keystone PrimaConnex, Neodent GM Helix, NobelActive 3.0, Straumann BLX). The provider selects the appropriate abutment based on the implant platform and clinical requirements. The device facilitates the attachment of crowns or bridges to the implant, restoring chewing function and aesthetics for the patient.

Clinical Evidence

No clinical or animal data included. Substantial equivalence is supported by non-clinical bench testing, including reverse engineering of OEM interfaces, static compression and compression fatigue testing (ISO 14801), and MRI safety assessment based on scientific literature.

The zirconia superstructure is straight only and is not to be designed to provide an angle or divergence correction.

For the Titanium Base abutment, the design parameters for the CAD/CAM zirconia superstructure are: Minimum wall thickness - 0.5 mm; Minimum post height for single-unit restorations – 4.0 mm; Maximum gingival height – 5.0 mm; and All zirconia superstructures are for straight abutments only. The design parameters for the CAD/CAM Titanium Blank custom abutment are:

Minimum wall thickness – 0.5 mm to 0.9 mm (varies by implant line); Minimum post height for single-unit restoration – 4.0 mm; Maximum Angle - 30°*; and Minimum gingival height - 0.5 mm; Maximum gingival height – 2.0 mm to 4.5 mm (varies by implant line). * Astra Tech® OsseoSpeed™ Plus (OsseoSpeed™ EV) compatible are limited to 0° maximum correction angle.

## PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included: reverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility; static compression and compression fatigue testing according to ISO 14801 and an assessment performed for MR Safety. For each compatible OEM implant line, except Astra Tech OsseoSpeed EV, worst-case constructs were subjected to static compression and compression fatigue testing.

Biocompatibility has been demonstrated through Predicate device testing according to ISO 10993-1, and ISO 10993-5. Sterilization validation was demonstrated through and leveraged from Predicate device testing according to ISO 17665-1 and ISO 14937.

Non-clinical worst-case MRI review was performed to evaluate the Subject device including all compatible implant fixtures, abutments, bars, and fixation screws and their respective material composition 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). 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 or animal data is included in this premarket notification.

### EQUIVALENCE TO MARKETED DEVICE

Overall, the Subject device is substantially equivalent in indications and design principles to the Predicate device listed above. Provided at the end of this summary are tables comparing the Indications for Use Statements and the technological characteristics of the Subject, Predicate device, and Reference devices.

Subject device abutments are substantially equivalent in intended use to the sponsor's K183518 Predicate device. They are both intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the maxilla and mandible to restore chewing function. Reference devices are also intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the maxilla and mandible to restore chewing function.

The Indications for Use Statement (IFUS) for the Subject device is substantially equivalent to that of the K183518 Predicate device. Differences in the list of compatible implant systems do not affect the intended use of the Subject and Predicate devices to provide support for single or multi-unit prosthetic restore chewing function.

Similarly, the differences between the Subject device IFUS and that of each Reference device are related to the specific device names and design features. None of these minor differences impact substantial equivalence with the Predicate device because all IFUS express equivalent intended use to facilitate dental prosthetic restorations, and the indications are expressed equivalently using different specific wording.

The following Subject device designs are substantially equivalent to the Predicate device K183518: temporary abutments (engaging and non-engaging); multi-unit straight abutments; multi-unit 17° angulated abutments; titanium base abutments (engaging and non-engaging); and titanium blank abutments.

The Subject and Predicate device abutment designs all have internace connections and are made of Ti-6Al-4V alloy (abutment screws). The Subject and Predicate devices each include titanium base abutment designs with a cut out region to allow for angled access to the abutment screw channel. The Predicate device supports abutment designs with angulation of 0° up to 30° by means of titanium blank abutments, validated through performance testing.

The Subject device includes designs for implant restorative platforms ranging from 2.9 mm. The Predicate K183518 similarly includes implant restorative platform sizes of 3.0 mm to 6.5 mm.

## Reference Device K120414 Astra Tech AB OsseoSpeed™ Plus

The K120414 Reference device is for support of substantial equivalence in terms of the OsseoSpeed™ Plus implant/abutment interface, prosthetic platform diameters. The OsseoSpeed™ Plus was subsequently renamed OsseoSpeed™ EV by the manufacturer, so either name may appear in device labeling or regulatory documentation.

### Reference Device K051614 Lifecore Biomedical, Inc. (Keystone)™ Internal Connection Implant System

The K051614 Reference device is for support of substantial equivalence in terms of the PrimaConnex™ Internal Connection Implant System implant/abutment interface, prosthetic platform diameters. Additionally, K051614 is used to support the addition of Multi-Unit Angled 30° abutments.

### Reference Device K163194 JJGC Industria e Comercio de Materiais Dentarios SA Neodent Implant System - GM Line

The K163194 Reference device is for support of substantial equivalence in terms of the Neodent Implant System - GM Line implant/abutment interface, prosthetic platform diameters. Additionally, K163194 is used to support the addition of healing abutments.

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

## Reference Device K102436 Nobel Biocare Nobel Active 3.0

The K102436 Reference device is for support of substantial equivalence in terms of the Nobel Active 3.0 implant/abutment interface, prosthetic platform diameters and implant diameters.

### Reference Device K173961 Institut Straumann AG Straumann® BLX Implant System

The K173961 Reference device is for support of substantial equivalence in terms of the Straumann® BLX lmplant System implant/abutment interface, prosthetic platform diameters and 4.5 mm, and 6.5 mm implant diameters. Furthermore, the K173961 Reference device provides support of substantial equivalence with respect to the use of 30° angulated Multi-Unit and healing abutments.

## Reference Device K181703 Institut Straumann® BLX Line Extension – Implants, SRAs and Anatomic Abutments

The K181703 Reference device is for support of substantial equivalence in terms of the Straumann® BLX Implant System implant/abutment interface, prosthetic platform diameters and the 3.75 mm implant diameter.

The Subject device is to be sterilized by the end-user, following the same process as the Predicate device K183518. Validation of the sterilization methods according to ISO 14937 are leveraged from the K183518 Predicate device.

The Subject device abutment designs are substantially equivalent to those of the K183518 Predicate device. Additional abutment designs, implant/abutment interfaces and dimensions are supported by Reference devices. Minor differences in the abutment designs, dimensions, sizes, or compatible OEM implant lines among the Subject device, the Predicate device, and the Reference devices do not affect substantial equivalence. These minor differences are related to the compatible OEM implant designs and are mitigated by mechanical performance testing.

### CONCLUSION

Overall, the Indications for Use statements for the Subject and Predicate devices are substantially equivalent differing only in the list of compatible implant system systems.

Overall, the Technological Characteristics, mode of operation and materials of the Subject device are substantially equivalent to that of the Predicate device with additional compatible implant systems and abutment designs supported by Reference devices.

Overall, the data included in this premarket notification demonstrate substantial equivalence of Preat Abutments to the sponsor's Predicate device.

The basis for the belief that the Subject device is substantially equivalent to the Predicate device and is summarized in the following comparison tables.
