Device Story

PRE-MILLED Abutment is a titanium alloy (Ti-6Al-4V ELI) component used to fabricate patient-specific dental abutments. It features a pre-manufactured connection interface for endosseous dental implants. Clinicians use CAD/CAM systems (specifically 3Shape) to design the patient-specific abutment based on intra-oral anatomy; the design is then sent to a validated milling center for final manufacturing. The device is placed over the implant shoulder and secured with a screw. It functions as a support for dental prostheses, restoring chewing function and aesthetics. Used in dental clinics; operated by dental professionals. Benefits include customized fit for individual patient anatomy while maintaining mechanical integrity of the implant-abutment connection.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing, including fatigue testing per ISO 14801:2016, biocompatibility testing per ISO 10993, and sterilization validation per ISO 17665/ANSI/AAMI ST79. Dimensional analysis and reverse engineering confirmed compatibility with reference implant systems.

Technological Characteristics

Material: Titanium grade Ti-6Al-4V ELI (ASTM F-136). Connection: Internal hex/conical. Dimensions: Various diameters (2.9mm to 5.7mm platform). Manufacturing: CAD/CAM (3Shape system). Sterilization: Non-sterile (end-user steam sterilization).

## Device Description

The PRE-MILLED Abutment is used in fabricating a patient-specific abutment in titanium alloy. It has a pre-manufactured connection interface that fits directly to an endosseous dental implant. It is made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-136).

The abutment is placed over the implant shoulder and mounted into the implant with the provided screw. The design and manufacturing of the patient-specific abutments take into consideration the shape of the final prosthesis based on the patient's intra-oral indications using CAD/CAM system.

Mechanical resistance of the implant-abutment connection is essential to ensure the correct longterm functional performance of the complete dental restoration. Dimensional compatibility and mechanical performance of abutments and screws together with the underlying implant are of primary importance. These concepts are the basis upon which the system design characteristics and functional performance are established.

The PRE-MILLED is a device that can only be sold, distributed, or used upon the order of an authorized healthcare provider, generally referred to as prescription (Rx) devices.

The proposed abutments are available in internal connection, and are compatible with Zimmer 3.1mmD Dental Implant System (K142082) and Screw Vent® and Tapered Screw Vent® (K013227).

#### Non-clinical Testing

The subject device was tested to evaluate its substantial equivalence according to the following standards.

- · Fatigue Test according to ISO 14801:2016
- · End User Steam Sterilization Test according to ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010.
- · Biocompatibility tests according to ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-10:2010.

Non-clinical test data was used to evaluate the proposed device's substantial equivalence compared to the primary predicate. The results of the above tests have met the criteria of the standard and demonstrated the substantial equivalence with the primary predicate.

Non-clinical testing was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments", and it consisted of testing finished assembled implant/abutment systems of the worstcase scenario through fatigue testing.

Dimensional analysis and reverse engineering of the implant-to-abutment connection platform were performed, including an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and cross-sectional images of the submission device and compatible implant body as well as the OEM implant body, the OEM implant abutment, and the OEM abutment screw. The testing aided implant to abutment compatibility and has established substantial equivalency of the proposed device with reference devices.

Clinical testing was not necessary to establish substantial equivalency of the device.

## Substantial Equivalence Discussion

PRE-MILLED Abutment incorporates the same material, indications for use, dimension, design, abutment seat, screw seat, anatomical site, connection, type of retention and technological characteristics as the primary predicate.

The Indications for Use of the subject and primary predicate are identical other than the compatible implant bodies. This difference is mitigated by fatigue testing, reverse engineering, dimensional analysis, and identification of reference predicate for compatible implant bodies. Both the predicate and subject devices are intended to be milled into patient-specific abutments using CAD/CAM technology under the manufacturing control of the sponsor.

Any differences in technology characteristics are accompanied by information that demonstrated the device is substantially equivalent as the predicate and do not raise different questions of safety and effectiveness than the predicate.

PRE-MILLED Abutments are compatible with reference devices (K142082 and K013227). Each PRE-MILLED abutment platform has a precision implant/abutment interface corresponding to the implant system predicate for that platform.

#### Conclusion

The PRE-MILLED Abutment constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its primary predicate. Therefore, PRE-MILLED Abutment and its predicate are substantially equivalent.
