It applies two laser-generated patterns of microscopic grooves to the implant collar. These micro-grooves engineer biological width and tissue attachment, inhibiting epithelial down-growth and promoting bone attachment/retention. Used by dental professionals in clinical settings for tooth replacement or denture support. The device functions as a physical surface treatment; it does not involve software or algorithms. Clinical benefit includes improved soft tissue and bone integration at the implant site. ## Clinical Evidence Evidence includes mechanical testing per FDA guidance, finite element analysis, animal studies, and clinical testing. Studies demonstrate that the Laser-Lok micro-textured surface enhances bone and soft tissue response compared to non-textured surfaces. No specific sensitivity/specificity metrics provided. ## Technological Characteristics Endosseous dental implant with laser-generated microscopic groove surface treatment on the collar. Mechanical strength validated via static and dynamic testing. No software or electronic components. ## Regulatory 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. ## Predicate Devices - Silhouette™ and Silhouette™ IC dental implants ([K032454](/device/K032454.md)) ## Reference Devices - Astra Tech Fixture ST ## Related Devices - [K032454](/device/K032454.md) — SILHOUETTE(TM) IC OR SILHOUETTE(TM) & LASER-LOK (TM) · Bio-Lok Intl., Inc. · Mar 4, 2004 - [K073268](/device/K073268.md) — BIOHORIZONS INTERNAL IMPLANT SYSTEM · BioHorizons Implant Systems, Inc. · Feb 8, 2008 - [K103291](/device/K103291.md) — BIOHORIZONS LASER-LOK ABUTMENTS FOR NOBEL BIOCARE · BioHorizons Implant Systems, Inc. · Nov 4, 2011 - [K031568](/device/K031568.md) — BICONITE SURFACE TREATMENT · Bicon, Inc. · Nov 23, 2004 - [K182070](/device/K182070.md) — BioHorizons Tapered IM Implants · BioHorizons Implant Systems, Inc. · Oct 10, 2018 ## Submission Summary (Full Text) {0}------------------------------------------------ K04/1136 # 510(k) Summary ### SUBMITTER: #### Submitted on behalf of: | | Company Name: | Bio-Lok International Inc. | |--------------------|--------------------------------------------------------------------------------------------------------|-------------------------------------------------------| | | Address: | 368 South Military Trail<br>Deerfield Beach, FL 33442 | | | Telephone: | (954) 698-9998 | | | Fax: | (954) 698-9925 | | by: | Elaine Duncan, M.S.M.E., RAC<br>President, Paladin Medical, Inc.<br>PO Box 560<br>Stillwater, MN 55082 | | | Telephone:<br>Fax: | 715-549-6035<br>715-549-5380 | | | CONTACT PERSON: | Elaine Duncan | | | DATE PREPARED: | April 27, 2004 | | | TRADE NAME: | Laser-Lok™ surface treatment for use with Silhouette™ &<br>Silhouette™ IC dental implant system | | | COMMON NAME: | Dental implant, Endosseous | | SUBSTANTIALLY EQUIVALENT TO: Laser-Lok surface treatment is a line extension (optional surface modification) to the Silhouette™ and Silhouette™ IC dental implants. These surface modified implants are substantially equivalent to the predicate the Silhouette™ and Silhouette™ IC dental implants previously cleared under 510(k) # 032454. Additionally, FDA has cleared similar surface treatments for dental implants, such as the surface treatment on the Astra Tech Fixture ST DESCRIPTION of the DEVICE: Laser-Lok™ is a surface technology in which two laser generated patterns of microscopic grooves are applied to the collar of the implant to engineer the biological width and tissue attachment to cither the Silhouette™ (hex-top) or Silhouette ™ IC (internal connection) dental implants. Soft tissue attachment to the Laser-Lok surface treatment and the alignment of its micro-grooves inhibits epithelial down-growth on Silhouette Implants. The LaserLok treated collar on the Silhouette Dental Implant has been shown to attach and retain bone adjacent to the implant 3,b a.
