Pt construct for him a complete denture after few days he came to u complaining from pain & white spots on the residual ridge do relief in that area & give him ointment & after few days he came again complaining the same but in another area the main cause is:
a- Uneven pressure on the crest of alveolar ridge.***
b- Increase vertical dimension.
