may I ask u to be more explanative as to why is the answer Intrusive Luxation...???
thank u

 

[dentist79]

For other questions posted number 3 and 4?

Is the answer for question 4 going to be Relining the Base area or Remaking the denture...due to the fact that after a few years there is resorption but because of rest seat the dentures do not settle...and hence loads to the posterior extension base leads to lifting up of the indirect retainer????😕 Please correct me...

For Q3: please answer...i dont know this one as i feel the first statement is right...thats all i know.....😀

thanks

1 is c
2 is intrusion because it would cause the vascular and the nerve fiber to get strangulated and hence cause necrosis... also some books say extrusive so i am in doubt ,for this ans
3 is c
4 is make new dentures
