This product is 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 and is removed after orthodontic treatment has been completed.
Orthodontic screw is designed to facilitate placement of orthodontic appliances such as wires, springs, and elastic ligatures.
The Orthodontic Screw is a dental device made of titanium alloy metal intended to be used as a fixed anchorage point for attachment of orthodontic appliances to facilitate the orthodontic movement of teeth.
It is 1.2, 1.4, 1.6 and 1.8mm in screw diameter and 6, 8, 10mm in length.
It is made of Titanium alloy (Ti-6Al-4V ELI).
There are two types of surface treatment one is non-treated (Machineed) another one is Acid etching
The provided text describes the regulatory submission for an Orthodontic Screw, which is a medical device, and includes a summary of nonclinical testing. It does not contain information about acceptance criteria for AI/ML performance, nor does it describe a study involving an AI device or human readers. Therefore, I cannot fulfill the request as it pertains to AI/ML device performance.
However, I can extract information regarding the nonclinical testing performed for this Orthodontic Screw:
1. A table of acceptance criteria and the reported device performance:
The document mentions three types of performance tests conducted. It states "We conducted performance test due to addition of smaller diameter Ø1.2mm Fracture load Test, Rotational fracture torque test, Axial pull-out strength test." However, the specific acceptance criteria (e.g., minimum fracture load, torque, or pull-out strength) and the reported device performance values are not provided in the document. The document only lists the types of tests performed.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
The document does not provide details on the sample size used for these performance tests, nor the data provenance (country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
This information is not applicable as the tests described are mechanical performance tests of a physical device, not an AI/ML system requiring expert ground truth for imaging or diagnostic tasks.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable for mechanical performance tests.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
Not applicable. This is a physical medical device, not an AI system that assists human readers.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
Not applicable. This is a physical medical device.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
For the three performance tests (Fracture load Test, Rotational fracture torque test, Axial pull-out strength test), the "ground truth" would be the experimentally measured physical properties of the Orthodontic Screw under specific load conditions. These measurements are typically derived from standardized testing procedures, not from expert consensus, pathology, or outcomes data in the context of device performance claims.
8. The sample size for the training set:
Not applicable. This is a physical device, not an AI/ML system.
9. How the ground truth for the training set was established:
Not applicable. This is a physical device.
Additional Information from the Document:
- Biocompatibility: Demonstrated by reference to K122171.
- Sterilization Validation: Demonstrated by reference to K072896 (gamma irradiation process).
- Surface Treatment Characterization: Demonstrated by reference to K122171.
- Clinical Studies: "No clinical studies are submitted."
- Substantial Equivalence: The claim of substantial equivalence is based on the device having the same principles of operation, material (Titanium alloy Ti-6Al-4V ELI, ASTM F 136), indication for use, and similar design to predicate devices. The performance tests were conducted due to the addition of a smaller diameter (Ø1.2mm) and new head types (Small Head, Bracket Head) and a change in surface treatment (Acid etching).

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification Osstem Implant Co., Ltd. concludes that the Orthodontic screw is substantially equivalent to the predicate devices as described herein.
§ 872.3640 Endosseous dental implant.
(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;
(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.
