• Device Name: MODIFICATION TO THE MAESTRO SYSTEM
• Applicant: BioHorizons Implant Systems, Inc.
• Product Code: NHA · Dental
• Decision Date: Aug 30, 2002
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 872.3630
• Device Class: Class 2
• Attributes: Therapeutic

Indications for Use

The Maestro System™ may be used in the mandible or maxilla for use as an artificial root structure for single tooth replacement or as abutments for fixed bridgework and denture retention.

Device Story

The Maestro System consists of screw-type dental implants, surgical components, and prosthetic abutments. This modification introduces a titanium-nitride (Ti-N) coating to the titanium alloy abutments. The yellow Ti-N coating provides an esthetically pleasing tint when visible through tissue and serves as a visual demarcation line to assist clinicians in determining implant depth during surgical placement. The device is used by dental professionals in clinical settings. The coating process does not alter the dimensional specifications, cleaning, packaging, or sterilization of the abutments. The device is provided sterile via radiation sterilization.

Clinical Evidence

Bench testing only. Adhesion and coating thickness assessed to IonBond specification MS 70-722; elemental composition verified via Energy Dispersive Spectroscopy in a scanning electron microscope. Biocompatibility confirmed per ISO 10993-1.

Technological Characteristics

Titanium alloy abutments with titanium-nitride (Ti-N) coating. Coating thickness and adhesion per IonBond MS 70-722. Sterilization via radiation (ANSI/AAMI/ISO 11137) to 10^-6 SAL. Biocompatibility per ISO 10993-1.

Indications for Use

Indicated for patients requiring single tooth replacement or fixed bridgework/denture retention in the mandible or maxilla.

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)

## Proprietary Name

The Maestro System™

#### Common Name

Screw-type Dental Implant

#### Classification Name

Endosseous implants, surgical components, and prosthetic attachments

## Predicate Device

The predicate device is The Maestro System™ , a screw-type dental implant system manufactured and distributed by BioHorizons Implant Systems, Inc. Authorization to legally market the predicate BioHorizons Maestro System has been documented under 510(k) numbers K010458, K960026, K964330, K972313, K010458, K020133, K020645.

The GingiHue™ abutment from Implant Innovations Inc. (31), is a competitive abutment utilizing a titanium nitride (Ti-N) coating. Authorization to legally market the predicate 3i abutment and implant system has been documented under 510(k) number K992334.

#### Device Description

The Maestro System is a comprehensive system containing implants, surgical components, and prosthetic components. This 510(k) submission notification is for the purpose of obtaining authorization to offer Ti-N coated prosthetic abutments as part of The Maestro System. The abutments will continue to be machined from titanium alloy but will undergo a Ti-N coating process. BioHorizons proposes to coat all exposed surfaces of the implant abutments during the coating process; current dimensional characteristics and specifications for abutments coated with Ti-N do not change. Cleaning, packaging and sterilization operations will be the same for the Ti-N coated abutments as for the non-coated abutments. In clinical practice, the implant and abutments surgical placement and restorative procedures will not change.

BioHorizons Implant Systems, Inc. Titanium-Nitride Coating Special 510(k) Notification - Device Modification 08/21/02

#### Device Description (cont'd)

The purpose of Ti-N coating implant abutments is two-fold: first, the yellow color of the Ti-N coating presents an esthetically-pleasing tint when visible through tissue, compared with the gray tint of uncoated titanium; second, the yellow color provides a distinct demarcation line at the interface of the implant body and the abutment, which will provide a visual aide in determining implant depth during the placement process.

The product is packaged using materials known in the industry to be appropriate for medical device packaging and will be provided sterile, validated in compliance to ANSI/AAMI/ISO 11137, Sterilization of healthcare products - Requirements for validation and routine control - Radiation Sterilization, with a minimum sterility assurance level of 10-6.

#### Intended Use

The indications for use of the Ti-N coated implants and abutments do not change from non-coated implants and abutments. The Maestro System may be used in the mandible and maxilla for use as an artificial root structure for single tooth replacement or as abutments for fixed bridgework and dental retention. The indication/intended use of the modified device as described in its previouslycleared labeling has not changed.

#### Technological Characteristics

The fundamental scientific technology of the modified device has not changed: all materials, suppliers, processing, packaging and sterilization methods remain the same with the exception of the additional Ti-N coating process. Ti-N coating has been cleared by FDA for use in a variety of implant medical device applications since first reviewed in the 1980s. Biocompatibility testing has been conducted on Ti-N using the International Organization for Standardization (ISO 10993-1) guidelines. This testing, and subsequent clinical applications, has demonstrated that titanium nitride is biocompatible and appropriate for human use in implant medical devices that come in contact with bone, skin, tissue, or blood. The proposed Ti-N modification to The Maestro System abutment components is substantially equivalent to all features of the predicate devices which may affect safety or effectiveness, because of the similarities in design, material, and intended use.

#### Non-Clinical Testing

Ti-N coating applied to The Maestro System abutments was assessed in a number of tests, including adhesion and coating thickness to lonBond specification MS 70-722, and elemental composition using Energy Dispersive Spectroscopy in a scanning electron microscope at the University of Alabama at Birmingham School of Dentistry.
