Can I get Emtone or CoolTone with a dental implant?

The dentist thinks I may have had a fracture when getting a root canal and I might have to get an implant. (Yes, I'm upset.) Can I still get Emtone or Cooltone if I have that metal in my mouth? IF so...Which one is likely to be less problematic? Or is it just too dangerous period...and should I only buy some sessions until then? Thanks so much.
