Indications for Use
The Lin/Liou Orthodontic Mini Anchor System (LOMAS) (Sterile) is intended to provide a fixed anchorage point for attachment of orthodontic appliances to facilitate the orthodontic movement of teeth. The device is used temporarily and is removed after orthodontic treatment has been completed. Screws are intended for single use only.
Device Story
LOMAS is a sterile orthodontic mini-anchor system consisting of screws used to provide temporary fixed anchorage for orthodontic appliances. The device is implanted to facilitate tooth movement and is removed upon completion of treatment. Intended for single-use only. Operated by orthodontists in a clinical setting. Benefits include providing a stable, temporary anchor point to improve the efficiency and precision of orthodontic tooth movement.
Clinical Evidence
No clinical data provided; substantial equivalence based on device design and intended use.
Technological Characteristics
Endosseous implant (screw) for orthodontic anchorage. Sterile, single-use device. Classified as Class II under 21 CFR 872.3640.
Indications for Use
Indicated for patients requiring orthodontic tooth movement; provides temporary fixed anchorage for orthodontic appliances. Contraindicated for patients where temporary anchorage is not required or appropriate.
Regulatory Classification
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.
