Hi Guest!

D7210 - Extraction, erupted tooth requiring removal of bone and/or sectioning of tooth, and including elevation of mucoperiosteal flap if indicated
D7220 - Removal of impacted tooth - soft tissue
D7230- Removal of impacted tooth - partially bony
D7240 - Removal of impacted tooth - completely bony
D7241 - Removal of impacted tooth - completely bony, with unusual surgical complications
D8090 - Comprehensive orthodontic treatment of the adult dentition

As for the CPT codes for extractions & ortho treatment, there is actually not 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 use the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures

Hope this helps!
