What implants are MRI safe?

The answer is no! Titanium is the most common metal used for dental implants, and it is completely non-reactive to magnetism. Because it is not magnetic, it will not interfere with an MRI. This means that your dental implant will not interfere with your scan, or cause any negative effects if you have an MRI.

Can MRI be done with orthopedic implants?

The authors conclude MRI is safe in patients with orthopedic implants because implant displacement and heating pose little risk to patients. A risk-to-benefit ratio is warranted, however, to assess the clinical utility and necessity of the study.

Are prosthetic eye MRI safe?

Metallic implants or prostheses can be potentially hazardous during magnetic resonance (MR) imaging because of movement or dislodgment of the foreign object. Magnetic eye implants have been reported to exhibit strong movement when placed in water and exposed to a field of 1.5 T.

How are hydroxyapatite implants used in the eye?

Hydroxyapatite: The Bio-eye hydroxyapatite (HA) ocular implant is a spherical (ball-shaped) implant composed of natural coralline HA. It is used to replace the volume of the orbit when the eye is surgically removed, or as a replacement implant in patients with a poorly functioning, pre-existing implant. Historically,…

How big are orbital implants in the eye?

In addition, thanks to new techniques, PMMA implants can have the same motility outcomes as much more expensive porous polyethylene implants. Gulden Ophthalmics manufactures Orbital Implants (also known as Eye Spheres) in several sizes: 10, 12, 14, 16, 18, 20, and 22 mm diameters.

How big is the Medpor orbital sphere implant?

MEDPOR® Orbital Spheres. Surgeons may possibly select from sphere implant diameters of 14 mm to 22 mm. A resterilizable sizer set is available for selecting the appropriate implant diameter at the time of surgery.
