Indications for Use
Magnacap is a magnetic abutment for implant retained dental and craniofacial prosthesis and root supported overdentures. Magnacap is engineered to fit several commercially available implant fixtures.
Device Story
Magnacap is a magnetic abutment system designed to provide retention for dental and craniofacial prostheses and root-supported overdentures. The device functions as a mechanical interface, attaching to commercially available dental implant fixtures to provide magnetic coupling for prosthetic appliances. It is intended for use by dental professionals in clinical settings to improve the stability and retention of removable or fixed-removable dental restorations. The device facilitates patient prosthetic function by providing a secure, removable magnetic connection.
Clinical Evidence
No clinical data provided; substantial equivalence determination based on device description and intended use.
Technological Characteristics
Magnetic abutment system for dental/craniofacial implants. Mechanical interface design compatible with existing commercial implant fixtures. Non-electronic, passive mechanical device.
Indications for Use
Indicated for patients requiring implant-retained dental or craniofacial prostheses and root-supported overdentures.
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.
