#### Description of Device:

The Straight Stud Attachment is indicated for use with dental implants to support and/or retain removable dental prostheses in the treatment of partially or totally edentulous patients to restore chewing function. The attachment screws into SFI Abutments which are screwed into endosseous implants.

The attachment consists of a modified ball, which screws into an SFI Abutment and a retaining female, which is processed into the denture. The retaining female engages the outside of the ball shape and allows retention of the prosthesis to the denture.

Sterngold SFI abutments are compatible with several implant systems that have been previously cleared under K130183 and K132814 - SFI Bar® Implant Abutments.

The Straight Stud Attachment is a straight attachment and is not intended for angulation of divergent implants. It has a 0.048" hex for tightening to the SFI abutment.

#### Intended Use of the Device:

The Straight Stud Attachment is indicated for use with dental implants to support and/or retain removable dental prostheses in the treatment of partially or totally edentulous patients to restore chewing function. The attachment screws into SFI Abutments which are screwed into endosseous implants.

The Straight Stud Attachment is compatible with all Sterngold SFI Abutments.

#### Summary Technological Characteristics:

The proposed devices are similar in terms of design, operating principles and intended use and have similar technological characteristics as the predicate devices. The materials used on these devices - titanium alloy, polyurethane (brown, green, yellow, black) were also used in legally marketed predicate devices.

A Failure Mode and Effects Analysis (FMEA) was performed to ensure safety of device.

#### Substantial Equivalence:

The proposed Straight Stud Attachment is substantially equivalent to the currently marketed predicate devices. The intended use, basic design, fundamental operating principles and manufacturing procedures are the same as the predicate devices. To ensure compatibility, the Straight Stud Attachment was designed, and manufactured according to manufacturer's specifications and controlled procedures and validated following a validation protocol in accordance with Design Control requirements per FDA CFR820.30.

#### Non-Clinical Performance Data:

The specifications for a reliable connection between the Straight Stud Attachment and the SFI implant abutments were developed by analyzing the SFI Abutment specifications. Non-clinical test data was used to support the substantial equivalency. Clinical testing was not necessary. Non-clinical testing consisted of analysis of the SFI abutment top portion (head) and Stud Attachment screw section, dimensional verification against drawing, and fit checks of attachment to SFI abutment on several samples to ensure connection was reliable and functional.

Retention force testing was conducted to ensure level of retention was acceptable.

Evaluation was based on FDA guidance "Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments".

Testing has shown that the Straight Stud Attachment is equivalent in performance characteristics to the predicate devices.

#### Conclusion as to Substantial Equivalence:

Based on the technological characteristics, non-clinical functional testing and comparison of indications for use, it can be concluded that the Straight Stud Attachment is substantially equivalent to the predicate devices.
