Device Facts

• Record ID: K200100
• Device Name: Abutment Design
• Applicant: 3Shape A/S
• Product Code: PNP · Dental
• Decision Date: Oct 7, 2020
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 872.3630
• Device Class: Class 2
• Attributes: Software as a Medical Device

Intended Use

Abutment Design is intended as an aid to the restoration of chewing function in partially or fully edentulous mandibles and maxillae. Abutment Design is intended for use by a dental practitioner or dental laboratory staff for designing the patient specific component of a two-piece, one-piece, or hybrid dental implant abutment. The resulting abutment design is intended to be used by the manufacturer of an endosseous dental implant abutment to create the final device.

Device Story

Abutment Design is a software-only CAD tool for dental practitioners and laboratory staff. It accepts 3D scan data (DCM, STL) of teeth, impressions, or stone models. Users design patient-specific abutment components using integrated CAD tools, constrained by manufacturer-provided parameters (e.g., post height, angulation, gingival margin) for 510(k)-cleared abutment systems. The software ensures only cleared systems are used. Output is a digital file (proprietary or STL) sent to a manufacturer to produce the final physical abutment. The device operates on standard Windows PCs. By facilitating precise, patient-specific design, it aids in restoring chewing function for edentulous patients.

Clinical Evidence

No clinical data. Bench testing only, including software, hardware, and integration verification and validation performed per FDA software guidance. Cybersecurity analysis conducted per FDA guidance.

Technological Characteristics

Software-only device programmed in C# and Delphi. Operates on Windows 7/8/8.1/10 (64-bit) PCs. Requires 8GB RAM, 1GB DirectX 11 video memory, and 500GB HDD. Supports DCM and STL file formats. Connectivity via Internet/TCP-IP for server-based design parameters. No patient contact.

Indications for Use

Indicated for use by dental practitioners or laboratory staff to design patient-specific components for two-piece, one-piece, or hybrid endosseous dental implant abutments in partially or fully edentulous patients.

Regulatory Classification

Identification

# Dear Jenny Axel:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

|-------------------------|------------------------------------|
| Trade/proprietary Name: | Abutment Design |
| Regulation Number: | 872.3630 |
| Classification: | Class 2 |
| Product Code: | PNP |
| Regulation Name: | Endosseous dental implant abutment |

#### Primary Predicate Device

The primary predicate device is 3Shape Abutment Designer™ (K151455) manufactured by 3Shape A/S.

The Abutment Design software for abutments (K200100), based on the information and supporting documentation provided, has the same intended use, scientific concept, and technical characteristics as the primary predicate device (K151455).

Both software devices are used by dental professionals for the design of endosseous dental implant abutments, and the devices ensure only FDA cleared abutment systems can be used.

Therefore, the Abutment Design software (K200100) and the predicate (K151455) are found to be similar in their intended use, supported anatomic areas and the available relevant features and functionalities.

## Indications for Use

Abutment Design is intended as an aid to the restoration of chewing function in partially or fully edentulous mandibles and maxillae. Abutment Design is intended for use by a dental practitioner or dental laboratory staff for designing the patient specific component of a two-piece, one-piece, or hybrid dental implant abutment. The resulting abutment design is intended to be used by the manufacturer of an endosseous dental implant abutment to create the final device.

#### Device Description

The Abutment Design software receives scan data containing topographical characteristics of real teeth, dental impressions, or stone models. The software provides the user with the ability to create matching endosseous dental implant abutments using computer aided design.

The Abutment Design is restricted to be used with 510(k) cleared abutment systems, and the design output from Abutment Design (the patient specific part of the abutment) must be manufactured according to the instruction of the selected abutment system.

The Abutment Design software includes design parameters from the 510(k) cleared abutment systems such as implant type, maximum and minimum dimensions (e.g., abutment post height, gingival height, angulation, gingival margin diameter, etc.). The design parameters, provided by abutment system manufacturers, for an abutment system are available via a 3Shape server when documentation of the 510(k) clearance of said implant system is presented to 3Shape.

Abutment Design has no patient contact being a software only device.

# Scientific Concept

The underlying scientific concept of the Abutment Design software is to apply digital imaging tools for computer aided design, CAD, of abutments.

The system supports the following types of digital data: DCM and STL

Image /page/7/Picture/1 description: The image shows the logo for 3Shape. The text "3shape" is written in a sans-serif font, with the "3" being slightly separated from the rest of the word. To the right of the word is a red triangle pointing to the right, with a smaller triangle cut out of the center.

Based on a comparison of intended use, indications, scientific concept, features and technical data, and test results, the Abutment Design software is found to be as safe and effective as the primary predicate device. Therefore, Abutment Design is found to be substantially equivalent with the primary predicate device.
