MRI and Dental Implants
Most orthopedic and titanium alloy dental implants are not magnetic. These include hip and knee replacements; plates, screws, and rods used to treat fractures; and cavity fillings. All of these metal implants can distort the MRI image if near the part of the body being scanned, but they will usually not cause problems. Even if you think the metal implant is compatible with the MRI machine, you must let the MRI personnel know in order to ensure this metal is compatible.

There should be no contraindication having an MRI done with dental implants. Typically implants are made from titanium which is not magnetic.
MRI's ok for those with dental implants
No worries with MRI's of patients with dental implants. The contain no iron or ferrous metals and are non-magnetic. You won't be thrown across the room, teeth first!

Getting an MRI should not be a concern with dental implants
The biggest concern with having an MRI for people with any type of "metal" implant would be that the implant would become displaced during the procedure or that it would heat up. MRI's use magnetic forces during the scan that can cause these things to happen. Most dental implants are made of titanium and not considered "magnetic" so theoretically it should not be a problem. It would be wise however, to consult with the physician who ordered the MRI as well as the technician performing the MRI and make them aware of any implants or metal prostheses you may have in your mouth.

Titanium Implants MRI
Titanium implants should be no problem with an MRI. An MRI uses a powerful magnet to scan the human body. It is a problem with things containing ferrous metals(i.e. iron and steel). Implants and the restorative materials on them typically contain non-ferrous materials only( titanium,gold,platinum, etc.) The one possible area might be if you have a removable prosthesis that uses magnets for retention. It is probably a good idea to take out any removable prostheses(dentures,bridges,etc.) before an MRI and leave them outside the MRI room.
