#### 510(k) Summary

## PACKAGING/LABELING/PRODUCT INFORMATION

Advertising material to be used for promotion of the Uniplant Dental Implant System will be consistent with the indications for use and other material shown herein.

Uniplant dental implants are packaged in a radiation sterilizable package consisting of an outer tamper evident container and an inner vial of glass or plastic. Sterilization is accomplished by means of Co6 gamma irradiation at a dose of 25 kGy (2.5 Mrad) minimum. Sterilization will be validated by the bioburden method. The sterility assurance level (SAL) that Universal Implant Systems intends to meet for the Uniplant dental implant is 106. The device is not represented to be "pyrogen free." Abutments and instruments will be packaged either sterile in a system similar to the implant packaging or non-sterile in plastic bags.

#### INTENDED USE

The Uniplant Dental Implant System is intended for surgical placement in the maxillary and/or mandibular arch to support crowns, bridges, or overdentures in edentulous or partially edentulous patients.

#### DEVICE DESCRIPTION

#### Design Characteristics

The Uniplant Dental Implant System is composed of a solid titanium alloy root-form implant and a solid conical abutment, with associated instruments. The implant is a screw-type, two-stage design, incorporating a titanium cover screw that seals the internal bore of the implant from the physiologic environment during healing. The implant is available in three diameters (3.4, 4.1 and 5.1 mm) and three implanted lengths (10 mm, 12 mm and 14 mm). The system includes surgical instruments such as drills, insertion modules and try-ins.

The system includes a solid conical abutment that is intended to the implant by engaging the threaded shaft of the abutment in the internal threaded bore of the implant. The abutment includes a cylindrical transmucosal portion and a tapered, grooved coronal portion, with an internal hex socket at the coronal end to facilitate attachment to the implant. A prosthesis may be fabricated by means of standard crown and bridge techniques for attachment to the abutment.

#### Material Composition

Implants and abutments for the Uniplant Dental Implant System are made from titaniumaluminum-vanadium alloy that meets ASTM designation F1472 (Standard Specification for Wrought Titanium -6Aluminum-4Vanadium Alloy for Surgical Implant Applications (UNS R 56400)). Uniplant implants have a smooth machined collar of 1.0 mm height and from that point to the apex are coated with a layer of plasma-sprayed hydroxyapatite (HA) to facilitate attachment of bone. An alternative surface treatment for the Uniplant is a resorbable blast media (RBM) treatment, in which acid soluble grit (hydroxyapatite) is used to roughen the surface in order to facilitate bone attachment. The surface is then treated with acid to remove any residual

{2}------------------------------------------------

any residual grit particles. The use of titanium, titanium alloy and HA coatings is widespread in commercially distributed, permanently implanted medical devices and the materials are widely considered to be biocompatible. Titanium is often used as a negative control in biocompatibility testing.

### EQUIVALENCE TO MARKETED PRODUCT

Universal Implant Systems, Inc. submits the following information to demonstrate that, for the purposes of FDA's regulation of medical devices, the Uniplant Dental Implant System is substantially equivalent in indications and design principles to the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices: "O" Company Threaded Implants and Fixed C&B Abutment (K923889, K950066, K961665, K973926), the Steri-Oss Replace HA-Coated Implant (K962845), and the Simpler Implant System (K974401, K974402, K974856, K974857).

#### Intended Uses

The indications for use for the Uniplant Dental Implant System and the predicate devices are substantially the same. All are intended for surgical placement in the maxillary and/or mandibular arch to support crowns, bridges, or overdentures in edentulous or partially edentulous patients.

#### Design and Materials

The design and functional characteristics of the Uniplant Dental Implant System and the "O" Company Threaded Implant are similar in their use of a root-form threaded design. The threads are intended to provide macroretention in bone and to increase the surface area for bone attachment relative to a smooth design. The threads of the Steri-Oss Replace implant and the Simpler threaded implant serve a similar function. The "O" Company Implant and Fixed C&B Abutment shares with the Uniplant Dental Implant System the method of attaching the abutment to the implant using a threaded abutment shaft. The Uniplant shares the use of Ti-6Al-4V with numerous marketed implants. It shares the use of an HA coating with the "O" Company Threaded Implant, the Steri-Oss Replace HA-Coated Implant, the Simpler HA-coated cylinder implant and numerous other marketed implants.

#### Hydroxyapatite Coating Characteristics

The characteristics of the HA coating used on the Uniplant Dental Implant System are shown in vendor master files. The Uniplant Dental Implant System HA coating has crystallinity, purity and mechanical properties at least as high as those of the coatings on currently marketed devices and at least as high as the suggestions of the FDA Guidance Document.
