Medical man’s impression about twisted pose (7)
I believe the answer is:
dentist
'medical man's' is the definition.
(dentist is a kind of medical man)
'impression about twisted pose' is the wordplay.
'impression' becomes 'dent' (dent is a kind of impression).
'about twisted pose' becomes 'ist' (I can't explain this - if you can you should believe this answer much more).
'dent'+'ist'='DENTIST'
Can you help me to learn more?
(Other definitions for dentist that I've seen before include "expert in oral examination" , "Occasional driller" , "Repairer of teeth" , "Someone who drills for a living?" , "Oral surgeon" .)
