| | Contact: Maria Rao, QA/RA Director<br>Ph: 508-226-5660 ext 1206 |
| Date: | July 23, 2015 |
| Device Generic Name: | Endosseous Dental Implant |

Classification: According to Section 513 of the Federal Food, Drug, and Cosmetic Act, the device classification is Class II

Product Code: DZE (21CFR 872.3640) NHA (21CFR 872.3630)

#### Predicate Devices:

The TRU Dental Implant System is substantially equivalent to other currently marketed dental implant systems that have been cleared by FDA through the 510(k) Premarket Notification process, including the Sterngold Acid Etch Dental Implant System, and Nobel Active Internal Connection Implant System.

## Product Description:

The TRU is a self-tapping, double thread screw implant with a micro groove section, manufactured from pure grade 4 titanium. The implant surface is acid etched. The implants are manufactured with four body diameters 3.5 mm, 4.3 mm, 5.0 mm, and 6.0 mm. The 3.5 mm implants have a Narrow Platform (NP) prosthetic head. The 4.3 mm, 5.0 mm, and the 6.0 mm implants have a Regular Platform (RP) prosthetic head. They provide for non-rotational single and multiple tooth restorations in both the maxilla and mandible. They are packaged sterile in a double blister, which contains the implant in a titanium tube. A special driver is available for the implants which simplant insertion by eliminating the need for an implant mount.

The proposed TRU Dental Implant will be available in a range of lengths and diameters.

| Thread Major Diameter (mm) | Overall Implant Length (mm) |
|----------------------------|-----------------------------|
| 3.5mm | 8mm 10mm, 12mm, 14mm |
| 4.3mm | 8mm 10mm, 12mm, 14mm |
| 5.0mm | 8mm 10mm, 12mm |
| 6.0mm | 8mm, 10mm |

The prosthetic components for the TRU implant System include Healing abutments, Straight Abutments and UCLA Abutments.

{4}------------------------------------------------

Healing Abutments are intended for placement onto the implant. As the tissue heals, it conforms to the contours of the abutment. As the gingiva heals, the tissue adapts to the form of the healing abutment, creating permanent oral access to the implant and prepares the gingiva for the restorative phase.

Straight Abutments attach directly to the implant and provide the transitional link between the head of the implant and the restorative components. They are designed to be used for screw retained multiimplant prostheses. They are available in a narrow platform with 1.5mm and a 3.0mm cuff size and in a regular platform with 1.5mm and a 3.0mm cuff size.

UCLA Abutments attach directly to the implant and provide a pattern for the creation of a screw retained veneered crown. They are available with two apical (bottom) ends; one with a hex to engage the hex of the implant and one without a hex that does not engage the implant. The engaging/hexed abutment is used on restoration of a single tooth to prevent rotation of the completed crown, and the non-engaging/non-hexed is used on multiple tooth restorations.

## Indications for Use:

The TRU Implant System can be used in dental implant applications for oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Implant retained restorations may consist of single crowns or bridges as well as complete or partial dentures. The TRU Implant System is intended for delayed loading. It is also indicated for immediate loading with good primary stability and appropriate occlusal loading.

The TRU Implant System is only intended for use with straight abutments. The TRU implant body is intended to be placed such no angle correction is necessary.

## Substantial Equivalence:

The proposed TRU Dental implants are substantially equivalent to other currently marketed dental implant systems that have been cleared by FDA through the 510(k) Premarket Notification process. The Indications for Use, basic design, fundamental operating principles are the same or similar as the predicate devices.

- . Nobel Active Internal Connection Implant (K071370) - Primary Predicate
- Sterngold Acid Etch Dental Implant System (K023580) Reference Predicate ●

Compatibility and substantial equivalency was determined by comparing the design features including diameters, lengths, cuff sizes, materials, implant-to-abutment connection platform, implant surface texture, abutment fixation method, and intended use of proposed device to predicate devices.

Any differences between the proposed devices and predicate devices do not render the device NSE.

{5}------------------------------------------------

## Technological Characteristics:

The TRU dental Implant provides the same or similar functions as well as design and technological characteristics as the predicate devices. In addition the surface treatment is identical to the cleared Sterngold Acid Etched Implant (K023580).

The materials, technology and processes used to produce the TRU dental implants and abutments are the same as other Sterngold Dental devices previously cleared by the FDA.

### Performance Testing:

Non clinical Testing was performed following "Guidance for Industry and FDA Staff -Class 11 Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments." Performance testing demonstrated that the device performs appropriately for the proposed indications for use.

Fatigue testing is not required because design features and technological features are similar to predicate devices; the implant body is not intended to be placed with any angle correction, and this submission does not contain any abutments for angle correction.

Proposed devices have the same sterilization process and radiation dose, same shelf life and biocompatibility as previous cleared Sterngold devices, therefore sterility, shelf life and bio-compatibility testing performed on previous cleared Sterngold devices is applicable to the proposed new devices. As a result, the TRU Dental Implant System including abutments is substantial equivalent to the predicates.

#### Conclusion:

Based on the above analysis, technological characteristics and performance testing, the subject device is substantially equivalent in intended use, material, design and performance to its predicates.
