Indications for Use

The Universal Base Conical Connection is a premanufactured prosthetic component directly connected to endosseous dental implants and is intended for use as an aid in prosthetic rehabilitation. The Universal Base Conical Connection consists of two major parts. Specifically, the titanium base and mesostructure components make up a two-piece abutment. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

Device Story

Universal Base Conical Connection is a two-piece dental abutment system comprising a titanium vanadium alloy base and a CAD/CAM-milled mesostructure. It integrates into a digital dentistry workflow: intra-oral scanning (3Shape TRIOS), CAD design (3Shape Abutment Designer), and milling (imes-icore CORiTEC). The device features a fixed upper shape and indexing feature to facilitate CAD/CAM design. It is used by dental professionals in a clinical/laboratory setting. The base is screwed onto Nobel Biocare internal conical connection implants. The system provides a standardized platform for custom mesostructure fabrication, aiding in prosthetic rehabilitation and crown support. The design library is encrypted and locked to ensure mesostructure fabrication remains within validated safety and performance specifications.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including dynamic fatigue testing per ISO 14801, biocompatibility evaluation per ISO 10993-1 (cytotoxicity, chemical characterization), and software verification/validation of the design library.

## Analysis of Differences Between Subiect Device and Predicate

The Universal Base Conical Connection and predicate device, Universal Base Abutment are both abutment systems intended to fit the Nobel Biocare dental implants. Both systems consist of a titanium abutment component and a mesostructured composed of VITA ENAMIC Implant Solutions (IS) (K153645) material. Furthermore, both systems feature a screwed abutment fixation which allows for a maximum abutment angulation correction of 20 degrees.

Discussion about the differences between the subject device and predicate is provided below.

### Design Feature - Compatible Implant Platform

The subject device differs from the predicate device in the compatible implant platform, the subject device is designed to be compatible with the internal connection implants. The predicate device is compatible with the implant connection external hex only. To facilitate the connection with the conical connection implants the lower portion of the universal abutment has been modified and differs from the predicate, these modifications are discussion further below. The post portion of the abutment remains the same as the predicate. All other features of the abutment are the same as the predicate, Universal Base Abutment (K180899).

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

## Differences:

Connection Shape: The subject device has a cone shape which extends into a hexagon shape at the apex of the abutment. The predicate has a hexagon shape at the apex of the abutment. The shape change facilitates the compatibility with the conical connection implant.

Abutment/Implant connection type: For the conical connection, the abutment is the male, the implant is the female connection, for the predicate, the abutment is the female connection and the implant is the male.

## Summary:

The design differences between the subject and predicate device do not raise different questions of safety or effectiveness compared to the predicate. Differences in technology were evaluated through performance testing.

## VIII. PERFORMANCE DATA

The following performance testing was submitted in this 510(K) to support substantial equivalence:

## Mechanical Testing

Worst case dynamic fatigue testing per ISO 14801:"Dentistry - Implants - Dynamic loading test for endosseous dental implants" was performed and demonstrated compliance with the minimum required fatigue properties of the Universal Base Abutment conical connection with a bonded VITA ENAMIC IS mesostructure.

## Biocompatibility Testing

The biocompatibility evaluation for the Universal Base Conical Connection was conducted in accordance with International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests:

- . Cytotoxicity
- Chemical Characterization .

The Universal Base Conical Connection is categorized as a long term, implant device with tissue bone contact according to ISO 10993-1. The Universal Base Conical Connection is made of titanium vanadium alloy (ASTM F136).

## Software Verification and Validation

Validation was completed on the Universal Base Conical Connection with the 3Shape TRIOS Scanner, 3Shape Abutment Designer Software (K155415), CORTEC imes-icore milling unit workflow. Software verification and validation testing was provided for the subject abutment design library to demonstrate use with the 3Shape Abutment Designer TM Software (K151455). Software verification and validation testing was conducted to demonstrate that

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

the restrictions prevent design of the mesostructure component outside of design limitations. including screenshots under user verification testing. In addition, the encrypted abutment design library was validated to demonstrate that the established design limitations and specifications are locked and cannot be modified within the abutment design library.

## Sterilization Validation

The proposed devices are provided non-sterile and intended to be steam sterilized by the end user. Steam sterilization analysis was performed following AAMI-TIR30, ISO 17665-1. and ISO 17665-2.

## Packaging

Since the subject device does not represent a new worst case in terms of device packaging and shelf life, data from the predicate was leveraged as follows: The packaging for the subject device is the same as the predicate. This is a thermoform tray with peel top lid. Therefore, no additional testing was required.

## IX. CONCLUSIONS

The Universal Base Conical Connection was evaluated for substantial equivalence using standard and/or comparative testing. In cases were the Universal Base Conical Connection could be demonstrated as not to represent the worst-case with respect to the predicates, data from these predicate devices was leveraged to support the subject device. Based on technological characteristics and non-clinical test data included in this submission, the Universal Base Conical Connection has been shown to be substantially equivalent to the predicate.
