Intended Use

The BioHorizons Maestro System™ is indicated for use as an artificial root structure for single tooth replacement or as abutments for bridgework and denture retention in the mandible and maxilla.

Device Story

Maestro System comprises endosseous dental implants, surgical components, and prosthetic attachments; designed to optimize strain distribution to bone to promote long-term interface maintenance. Implants are screw-form, available in various diameters (3.5, 4.0, 5.0 mm) and lengths, tailored to specific bone density (D1-D4) and volume classifications. Used by dental surgeons in clinical settings for tooth replacement or denture retention. Output is the physical implant structure integrated into the jawbone to support prosthetic restorations. Benefits include improved biomechanical performance and stability for dental prosthetics.

Clinical Evidence

Bench testing only. Evaluation consisted of mechanical testing of the implant and bioactive coating mechanical tests.

Technological Characteristics

Titanium alloy (ASTM F 136) screw-form implants; available with titanium plasma-spray (TPS) or hydroxyapatite (HA) coatings; diameters 3.5-5.0 mm; designed for specific bone density (D1-D4) and volume (Division A, B, C-h) classifications.

Indications for Use

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

Regulatory Classification

Identification

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.

Special Controls

*Classification.* (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. 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.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.

#### Device Description

The Maestro System™ is a comprehensive system containing implants, surgical components, and prosthetic components. The implants are specifically designed to optimize strain distribution to contiguous bone under functional loading in order to promote strain-induced bone growth and interface maintenance over the long-term. This bone growth and interface maintenance over the long-term. This improvement in biomechanical performance is achieved by optimizing implant designs specifically for each bone density classification (D1, D2, D3, and D4) and bone volume classification (Division A, B, and C-h) in the mandible and maxilla.

Four implant designs, corresponding to each bone density and bone volume classification, are available in 3.5, 4.0,and 5.0 mm diameters. Each implant design, manufactured from titanium alloy conforming to ASTM F 136, is available in several lengths and may feature a titanium plasma-spray (TPS) or hydroxyapatite (HA) coating. The following table provides a comprehensive summary of implant diameter, length, and coating.

| Diameter (mm) | Design | Lengths (mm) | Coating |
|---------------|--------|--------------|----------|
| \$3.5 | D2 | 9, 12, 14 | Uncoated |
| | D3 | 9, 13, 15 | TPS |
