Intended Use

BioHorizons Simple Solutions with Laser-Lok is an abutment system that includes healing abutments for contouring tissue and final restorative abutments for cementing a prosthesis. The abutment system may be used for a single or multiple unit restoration and is compatible for use with BioHorizons Internal and Tapered Internal implant systems and Zimmer Dental ScrewVent and Tapered ScrewVent implants with 3.5mm, 4.5mm and 5.7mm internal hex-connection mating platform diameters.

Device Story

System of machined titanium alloy healing and final restorative abutments; features Laser-Lok micro-machined grooves on abutment margin. Used by dental clinicians in clinical settings to support single or multiple unit dental restorations. Laser-Lok surface promotes physical connective tissue attachment; inhibits epithelial cell downgrowth; enables crestal bone attachment. Compatible with specific BioHorizons and Zimmer Dental internal hex-connection implants. Clinician selects appropriate abutment diameter and collar height; attaches to implant to contour tissue or cement prosthesis. Benefits include improved peri-implant hard and soft tissue healing compared to traditional machined surfaces.

Clinical Evidence

Prospective canine study evaluated bone and soft tissue healing patterns. Four cohorts compared Laser-Lok vs. machined-surface healing abutments on RBT-treated implants. Results demonstrated significant improvement in peri-implant hard and soft tissue healing with Laser-Lok. Histological analysis showed laser-ablated microchannels enabled intense fibroblastic activity and connective tissue fiber orientation perpendicular to the abutment surface, acting as a physiologic barrier to apical junctional epithelium migration.

Technological Characteristics

Titanium alloy (ASTM F136) endosseous dental implant abutments. Features Laser-Lok micro-machined grooves on abutment margin. Available in 3.5mm, 4.5mm, 5.7mm diameters and 0.8mm, 1.8mm, 2.8mm collar heights. Sterilized via radiation (ANSI/AAMI/ISO 11137). Mechanical connection via internal hex.

Indications for Use

Indicated for patients requiring single or multiple unit dental restorations using compatible BioHorizons or Zimmer Dental internal hex-connection implants. Used for tissue contouring (healing abutments) and prosthesis cementation (final restorative abutments).

## Device Description

BioHorizons Simple Solutions with Laser-Lok is an abutment system comprised of machined titanium endosseous dental implant healing abutments and final restorative abutments supplied in platform diameters of 3.5mm, 4.5mm and 5.7mm with collar heights of 0.8mm, 1.8mm and 2.8mm. Abutment material is titanium alloy as specified in ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy (UNS R56401) for Surgical Implant Applications.

The devices are further processed by applying patterns of micro-machined grooves or channels, known as Laser-Lok, to a specified portion of the abutment margin. The product is packaged using materials known in the industry to be appropriate for medical device packaging and is provided with a minimum sterility assurance level of 10°, validated in compliance with ANSI/AAMI/ISO 11137-1 Sterilization of healthcare products -- Radiation -- Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices and ANSI/AAMI/ISO 11137-2 Sterilization of healthcare products - Radiation -- Part 2: Establishing the sterilization dose.

## Technological Characteristics

The fundamental scientific technology of the BioHorizons Simple Solutions with Laser-Lok is substantially equivalent to the existing abutments that are designed to mate with the implant components of the referenced predicate devices. The devices are further processed by applying Laser-Lok to a specified region of the abutment margin.

Laser-Lok is a surface feature in which patterns of micro-machined grooves are applied to the abutment margin, providing a roughened surface to establish a physical, connective tissue attachment (unlike Sharpey fiber attachment). This tissue connection:

- 1) is functionally oriented,
- 2) inhibits epithelial cell downgrowth and
- 3) enables crestal bone attachment adjacent to the implant.

All materials, suppliers, processing, packaging and sterilization methods remain the same as those utilized for the predicate BioHorizons implant systems (K073282, K073268 and K071638), and the Laser-Lok feature is substantially equivalent to that cleared for the BioHorizons Laser-Lok 3.0 Implant System (K093321). The BioHorizons Simple Solutions with Laser-Lok, which is the subject of this 510(k), is substantially

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

equivalent to all features of the predicate implant devices which could affect safety or effectiveness because of the similarities in design, materials and intended use.

#### Summary of Testing

The data presented in this 510(k) submission supports the substantial equivalence of the BioHorizons Simple Solutions with Laser-Lok to the specified predicate devices with respect to performance, safety and effectiveness. A prospective study was conducted in a canine model to evaluate bone and soft tissue healing patterns when Laser-Lok microgrooves are applied to dental implant abutments. The study consisted of four cohorts - Group A: Laser-Lok healing abutment on an RBT implant: Group B: Laser-Lok healing abutment on an RBT implant with a machined area; Group C: Machined healing abutment on an RBT implant; and Group D: Machined healing abutment on an RBT implant with a machined area. Laser-Lok and machined-surface healing abutments were randomly assigned to internal-connection implants that were either fully RBT treated or RBT-treated with a 0.3mm machined collar. Each group received nine implants with abutments placed at the time of surgery. The results demonstrate significant improvement in peri-implant hard and soft tissue healing on the Laser-Lok healing abutments as compared to traditional machined abutment surfaces.

Nevins et al concluded that the presence of the 0.7-mm laser-ablated microchanneled zone consistently enabled intense fibroblastic activity to occur on the abutment-orooved surface, resulting in an interlacing complex of connective tissue fibers onented perpendicular to the abutment surface that served as a physiologic barrier to apical JE migration.
