No
The device description and performance studies focus on the mechanical properties and sterilization of titanium screws and accessories, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
A therapeutic device is typically involved in the diagnosis, treatment, or prevention of disease. This device is used for the fixation of bone graft materials during bone regeneration, which is a supportive rather than a directly therapeutic function.
No
The device is described as a bone fixation system using screws to regenerate bone in the oral cavity, which is a therapeutic function, not a diagnostic one.
No
The device description explicitly details physical components made of titanium alloy (screws, driver, cassette) and their material properties and testing, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description and Intended Use: The Intra-Lock Bone Fixation System is a system of screws and accessories used for the physical fixation of bone graft, bone filling materials, and barrier membranes within the oral cavity. It is a surgical implant/device used directly on the patient's anatomy.
- Lack of Diagnostic Testing: The description does not mention any testing of biological samples or any diagnostic purpose. Its function is purely mechanical and structural.
Therefore, the Intra-Lock Bone Fixation System falls under the category of a surgical device or implant, not an in vitro diagnostic.
N/A
Intended Use / Indications for Use
The Intra-Lock Bone Fixation System is indication and fixation of bone graft, bone filling materials, and/or barrier membranes used to regenerate bone in the oral cavity.

Device Description
The Intra-Lock Bone Fixation System consists of titanium alloy self-tapping screws, which are tapered and have a minimum diameter of 1.5mm with lengths of 3mm, 6mm, 7mm, 8mm, 9mm, 10mm and 11mm and a maximum diameter of 2.0mm with lengths of 4mm, 5mm, 9mm, 11mm, 13mm, and 15mm. Tenting screws are also available in the 1.5 mm diameter. The spacer part of the tenting screws is available in 2mm, 6mm, 8mm and 10mm lengths. The screws are manufactured using Ti-6Al-4V alloy (ASTM F-136) and adhere to standards tested under ASTM F-543. This system also includes accessories used to fixate the screws, membranes or bone graft to the host bone including a tapered driver, and a cassette. The screws are designed for removal from the patient after such time when sufficient bone regeneration is demonstrated. The devices are sold non-sterile. Single-use only.

8. Non-Clinical Performance Data
As part of demonstrating safety and effectiveness of Intra-Lock Bone Fixation System and in showing substantial equivalence to the predicate devices that are subject to these 510(k) submissions, Intra-Lock Bone Fixation System completed a number of non-clinical performance tests. The Intra-Lock Bone Fixation System meets all the requirements for overall design, sterilization, and biocompatibility results confirming that the design output meets the design inputs and specifications for the device.
Biocompatibility testing per ISO 10993 was not conducted for the Intra-Lock Bone Fixation implant because the materials and manufacturing methods are identical those used in the Intra-Lock OP Dental Implant (K130140) and the anodization process is identical to that used in the Intra-Lock Dental Implant with Blossom (K103194). All Intra-Lock products are manufactured at Intra-Lock Manufacturing. Biocompatibility testing per ISO 10993-1 was not conducted for the Intra-Lock Bone Fixation instruments because their patient contact materials are medical grade 455 and 7-14 stainless steel which is well-known to be biocompatible in the intended applications
The Intra-Lock Bone Fixation System passed all the mechanical testing in accordance with ASTM F543-13 shown below to support substantial equivalence of the subject device:
- Torsion Testing - All tested Unifix screws vielded and fractured whereas the predicate screw head stripped.
- Axial Pullout Testing - No failures of the test specimen were observed. The screw pulled out of the bone foam
- Driving Torque Testing - No failures were observed; the screw pulled from the foam block
- Cleaning and Sterilization Testing - Concluded that the Intra-Lock Bone Fixation System Kit can be steam sterilized to a sterility assurance level of at least 10 $ per ISO 17665-1:2006(R)2013.

9. Clinical Performance Data
There was no human clinical testing required to support the medical device as the indications for use is equivalent to the predicate device. These types of devices, including the predicate devices, have been on the market for many years with proven safety and efficacy for the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the device.
10. Statement of Substantial Equivalence
By definition, a device is substantially equivalent to a predicate device has the same intended use and the same technological characteristics as the previously cleared predicate device. Or the device has the same intended use and different technological characteristics that can be demonstrated that the device is substantially equivalent to the predicate device, and that the new device does not raise additional questions regarding its safety and effectiveness as compared to the predicate device(s).
The Intra-Lock Bone Fixation System, as designed and manufactured, is determined to be substantially equivalent to the referenced predicate device(s).
