No
The device description clearly describes a physical, surgically implanted screw made of titanium alloy, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description: The Orthodontic Fixation Screw [Smart Anchor Miniscrew] is a physical implant surgically placed in the bone. It is used to provide mechanical support for orthodontic treatment.
- Intended Use: The intended use is for temporary anchorage during orthodontic treatment, which is a mechanical process of straightening teeth.
- No Specimen Analysis: The description does not mention the analysis of any biological specimens.
The device is a surgical implant used for mechanical support, not for diagnostic testing of biological samples.

Device Description
The Orthodontic Fixation Screw [Smart Anchor Miniscrew] is an orthodontic screw used for straightening of irregular teeth. It is designed for indications such as malocclusion treatment, straightening of irregular teeth, improvement of intermaxillary space and occlusion, and maintenance after orthodontic treatment.
It is surgically placed in the bone of the upper or lower jaw arches to provide support for orthodontic devices and it is used temporarily, removed after orthodontic treatment has been completed. Orthodontic screw is designed to facilitate placement of orthodontic appliances such as wires, springs, and elastic ligatures
Orthodontic Fixation Screw [Smart Anchor Miniscrew] is made of Titanium Alloy (Ti)-6AL-4V), which meets ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications, which are widely used for surgical implants with well-known biocompatibility. The head of the screw is through hole head type. The head of the Orthodontic Fixation Screw [Smart Anchor Miniscrew] is designed to apply various orthodontic tools. There is a hole in the screw head through which a wire can be passed to fix the mandible and maxilla in orthodontic treatment. Also, the design accommodates the use of the screw with the orthodontic appliances (bracket, wire, and elastic band etc.). The Orthodontic Fixation Screw [Smart Anchor Miniscrew] is available in in diameters of 1.2, 1.4, 1.6, 1.8, and 2.0mm and lengths of 8 and 10mm. The Orthodontic Fixation Screws with a diameter of 1.4mm and greater are also available in a 6mm length version.

(a)
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.(b)
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;

Information provided in these 510(k) submissions shows that the Orthodontic Fixation Screw [Smart Anchor Miniscrew] is substantially equivalent to the predicate devices, in terms of indications for use, device design, function and performance related to technological characteristics. Predicate devices are made of the same material as the subject device, titanium Alloy (ASTM F136) same as our device material.
Differences between the proposed and predicate device are not expected to affect the overall performance of the device. These differences include diameter, length and head shape in design.
For diameter of Ø 1.2mm, performance tests were conducted, including Fracture Load Test. Rotational fracture torque test, and Axial pull-out strength test. The subject device. Orthodontic Fixation Screw [Smart Anchor Miniscrew], features a smaller diameter than does the primary predicate whose smallest diameter is 1.4mm. To address the smallest diameter device found in the subject device, a reference device having the same 1.2mm diameter was introduced to this submission. As a result, the diameter of Ø 1.2mm does not impact substantial equivalence of the subject device to its primary predicate.
Biocompatibility testing:
The subject device is manufactured from Titanium alloy (conforming with ASTM F136) with a history of safe use. Cytotoxicity testing per ISO 10993 was performed to mitigate the risks associated with materials used during manufacturing, including cytotoxicity, hypersensitivity, intracutaneous reactivity, acute systemic toxicity and bone implantation, according to following standard below:
ISO 10993-1 Biological Evaluation of Medical Devices –Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process

ISO 10993-12 Biological evaluation of medical devices -- Part 12: Sample preparation and reference materials
Sterilization:
Device is provided Non-Sterile (Steam sterilized by end user). Sterilization by moist heat was validated by ISO 17665-1 and ISO 17665-2.
Non-clinical Performance Testing Summary:
Orthodontic Fixation Screw [Smart Anchor Miniscrew] tested visual and the dimension which is design characteristics based on manufacturer declared performance.
The following comparative bench tests were conducted to demonstrate substantial equivalence to the primary predicate device (K161335) using FDA recognized standard methods:
- Axial Pullout Strength test: ASTM 543-13
- Torsional Strength test: ASTM 543-13
- Insertion-Removal Torque Test: ASTM 543-13
A risk analysis was conducted based on ISO 14971:2012 Medical devices – Application of risk management to medical devices.
Clinical Testing Summary:
No clinical performance testing was necessary for the demonstration of substantial equivalence.
Conclusion
The subject device has identical indications for use, is made of the same materials and has similar dimensions and characteristics as the primary predicate device. The subject device is manufactured from material of the Titanium Alloy that is used generally in this kind of endosseous dental implant device. Differences in physical dimensions (screw body diameter) between the subject device and its primary predicate are addressed by the (K161197) reference device. The subject device, Orthodontic Fixation Screw [Smart Anchor Miniscrew], is substantially equivalent in intended use and technological characteristics to the primary predicate device as described in this summary .
