Device Story

Patient-specific metallic dental restorative device; manufactured via CAD/CAM milling from titanium alloy (ASTM F136). Input: digital scans of patient dental impressions. Output: custom-milled suprastructure (Type A for removable, Type B for fixed prostheses) attached to dental implant abutments via OEM prosthetic screws. Used in clinical dental settings by dentists/prosthodontists to support multi-unit restorations. Device facilitates chewing function restoration. No internal software/algorithm; purely mechanical restorative component.

Clinical Evidence

Bench testing only. Evidence includes sterilization validation (ISO 17665-1/2), biocompatibility (ISO 10993-5/12), and reverse engineering analysis to confirm compatibility with OEM abutments. No clinical data included.

Technological Characteristics

Material: Titanium-6 Aluminum-4 Vanadium ELI alloy (ASTM F136). Design: Patient-specific CAD/CAM milled suprastructure. Connectivity: None. Sterilization: Supplied non-sterile, end-user sterilized. Form factor: Custom-milled bar/frame with 2-10 cylinders.

Indications for Use

Indicated for partially or fully edentulous patients requiring dental restoration via attachment to a minimum of two dental abutments. Compatible with specific OEM abutment systems (e.g., Astra Tech, DESS, Nobel Biocare, Straumann, Zimmer).

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

# SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to expand the Osteon Precision Milled Suprastructure cleared under K212676 to add additional OEM compatibility to DESS Abutments, Nobel Biocare Abutments, and Straumann Abutments.

The Osteon Precision Milled Suprastructures (also referred to as superstructures) are metallic dental restorative devices that are intended to be attached by screw retention to dental implant abutments to aid in the treatment of partial and totally edentulous patients for the purpose of restoring function. These suprastructures attach to dental implant abutments using the prosthetic screws from the original equipment manufacturers (OEM) and are used to support the final multi-unit restoration.

The Osteon Precision Milled Suprastructure is designed for an individual patient from scans of the patient's dental impression. The suprastructure is manufactured with the aid of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technology. All CAD/CAM fabrication is performed by Osteon Medical.

Osteon Precision Milled Suprastructures facilitate the attachment of both removable and fixed dental prosthesis and hence are categorized as Type A and Type B.

- . Type A: Intended to act as a supporting structure to facilitate the attachment of removable dental prosthesis and include Primary Bar and Nexus Removable Bar.
- . Type B: Intended to act as a supporting structure to facilitate the attachment of fixed dental prosthesis and include Melbourne Bar and Nexus Fixed Bar

| Description | Type A<br>(For Removable Prosthesis) | | Type B<br>(For Fixed Prosthesis) | |
|--------------------------------------------|--------------------------------------|---------|----------------------------------|---------|
| | Minimum | Maximum | Minimum | Maximum |
| Total Cylinders | 2 | 10 | 2 | 10 |
| Suprastructure Span Between Cylinders (mm) | 1 | 30 | 1 | 30 |
| Suprastructure Height (mm) | 3 | 12 | 3 | 22 |
| Suprastructure Width (mm) | 3.4 | 12 | 3.4 | 12 |
| Distal Cantilever Section (mm) | 0 | 15 | 0 | 15 |
| Cylinder Height (mm) | 0 | 4.6 | 0 | 4.6 |
| Cylinder Diameter (mm) | 4.5 | 8 | 4.5 | 8 |

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

### MATERIAL COMPOSITION

The Osteon Precision Milled Suprastructure is manufactured from titanium alloy conforming to the requirements of ASTM F136 Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401). This material is identical to that of the primary predicate device K212676.

### PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included: sterilization validation according to ANSI/AAMI/ISO 17665-1 and ISO 17665-2, leveraged from K212676; biocompatibility

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

according to ISO 10993-5 and ISO 10993-12 leveraged from K212676: and reverse engineering analysis of OEM abutments to confirm compatibility. No clinical data were included in this submission.

# EQUIVALENCE TO MARKETED DEVICES

The subject device is substantially equivalent in indications and design principles to the primary predicate device listed above. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the subject device and the primary predicate device.

The subject device is substantially equivalent in intended use to the primary predicate device cleared in K212676. The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the primary predicate K212676, except for the list of compatible OEM implants.

The subject device is identical in design, materials and technological characteristics to the corresponding primary predicate device K212676. There have been no changes to the bars, and they remain the same as the primary predicate K212676. New bar cylinders (mating components) have been designed to accommodate the new compatible abutments that, other than the compatibilities, are identical to the bar cylinders that were cleared in the primary predicate K212676. Fatigue testing was not performed since the subject devices are abutment-borne and are not intended to compensate for angulation in excess of the maximum angulation of OEM angled abutments in each reference device clearance, as outlined in the Indications for Use Statement.

The subject device is to be sterilized by the end-user, the same as primary predicate device K212676.

The subject device is to be manufactured from the same materials and in the same facilities using the same manufacturing processes as used for the Osteon Precision Milled Suprastructure previously cleared in K212676. Therefore, no new biocompatibility testing has been performed, as the subject device is substantially equivalent to the predicate devices in K212676 with regard to materials and processing.
