I know implants are made of metal. Is it safe to have them inside the body?

Yes, you can rest assured. The titanium used in implants is a biocompatible material that has been used for decades in medical applications such as artificial joints, and rejection or allergic reactions are known to be very rare. Because it has almost no magnetic properties, it generally doesn't interfere with MRI scans either. However, if you have a history of metal allergies, please let us know during your diagnosis — we can discuss alternative materials such as zirconia if needed.
