Hi guest!

Great question.

For the implants:

21248 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); partial(3or less)
21249 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); complete (4 or more)

As for the bridge, those procedures do not have direct crosscodes we are aware of, so you can either bill the "D" code on the medical claim (many insurers these days will process "D" codes when they are medically necessary services), or you can try the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures

Hope this helps!
