Intended Use

The Legacy Abutment System is intended for use with dental implants in the maxillary and/or mandibular arches to provide support for crowns, bridges, or overdentures for edentulous or partially edentulous patients. The Legacy Abutment System is compatible with implants that have mating diameters, lead-in bevels, internal hex sizes, and 1-72UNF internal threads, as shown in the Zimmer Dental Tapered Screw-Vent Surgical Manual. Implant Direct LLC will monitor the compatible implants for modifications to ensure future compatibility. In the event of any modification, Implant Direct LLC will either modify the Legacy abutment to ensure compatibility, or cease claiming compatibility to the modified Zimmer Dental Screw-Vent implants.

Device Story

Legacy Abutment System consists of titanium alloy components (cement-retained and screw-retained) designed to interface with specific Zimmer Dental Tapered Screw-Vent implants; provides foundation for dental prosthetics (crowns, bridges, overdentures). Used by dental clinicians in clinical settings. Components include straight, scalloped, and angled bodies with varying cuff heights/diameters to match implant interfaces. Device functions as mechanical support post; no electronic or software components. Clinician selects appropriate abutment based on patient anatomy and implant site; secures to implant via internal hex and screw mechanism. Benefits include restoration of dental function and aesthetics for patients with missing teeth.

Clinical Evidence

No clinical data. Substantial equivalence is based on design comparison and technological characteristics.

Technological Characteristics

Material: Titanium alloy. Design: Hex-engaging posts; straight, scalloped, and angled configurations. Interface: Compatible with Zimmer Dental Tapered Screw-Vent implants (specific diameters, lead-in bevels, internal hex, 1-72UNF threads). Packaging: Non-sterile. Energy source: None (mechanical).

Indications for Use

Indicated for edentulous or partially edentulous patients requiring support for crowns, bridges, or overdentures in maxillary or mandibular arches.

Regulatory Classification

Identification

Company Name: Implant Direct LLC Address: 27030 Malibu Hills Road Calabasas Hills CA 91301 Telephone Number: [phone] Fax Number: [phone] Registration Number: 3001617766 Submitter's Name: Leslie Terry Contact Person: Patty McMahon Date Summary Prepared: January 5, 2006 - amended May 3, 2006

## Classification Name: Abutment, Implant, Dental, Endosseous Common/Usual Name: Endosseous dental implant abutment Device Trade Name: Legacy Abutment System

The primary device used for comparison in this summary is the Screw-Vent Dental Implant System (K011028).

### 1. Description:

The Legacy Abutment System consists of cement retained and screw-retained components. All abutments have the same identical interface diameters as the predicate abutments to function with the corresponding mating Screw-Vent Implants manufactured by Zimmer Dental. The cement retained abutments are offered in a straight body with a straight or scalloped prosthetic margin and in an angled body with a scalloped prosthetic margin. The screw-retained abutments are offered in different cuff diameters and heights to accommodate for the different implant interfaces and tissue heights.

### 2. Intended Use:

The Legacy Abutment System is intended for use with dental implants in the maxillary and/or mandibular arches to provide support for crowns, bridges, or overdentures for edentulous or partially edentulous patients.

The Legacy Abutment System is compatible with implants that have mating diameters, lead-in bevels, internal hex sizes, and 1-72UNF internal threads, as shown in the Zimmer Dental Tapered Screw-Vent Surgical Manual.

Implant Direct LLC will monitor the compatible implants for modifications to ensure future compatibility. In the event of any modification, Implant Direct LLC will either modify the Legacy abutment to ensure compatibility, or cease claiming compatibility to the modified Zimmer Dental Screw-Vent implants.

{1}------------------------------------------------

### 3. Technological Characteristics:

The Legacy abutments provide support for crowns, bridges, or overdentures in edentulous or partially edentulous patients for cement retained and screw retained restorations following the same preparation principals as the predicate devices. The Legacy abutments have similar technological characteristics and the same intended use as the predicate device. The Legacy abutments are packaged non-sterile for sale unlike the predicate devices packaged sterile. The Straight, Scalloped, and Angled Abutments are designed to function as a foundation for cemented restorations. The Screw-Retained abutments are designed to function as a foundation for scrow-retained restoration.

### 4. Comparison Analysis:

The overall designs of the Legacy Abutment System are similar to the predicate devices. The following Tables 1, 2, 3 summarize the predicate device comparison analyses with the Legacy Abutments.
