Complete dentures opposed by natural teeth

Question 1

Complete upper denture opposing lower natural teeth - effects

Answer 1

presence of natural teeth mean that high levels of force can be developed against the upper mandibular alveolar ridge
leads to
- trauma to maxillary denture bearing area
- instability of denture
- fibrous ridge

Question 2

How is a a fibrous ridge formed?

Answer 2

as a result of alveolar resorption and fibrous tissue replacement

Question 3

Fibrous ridge - problems

Answer 3

tissue easily displaced
tipping of prosthesis

Question 4

how to reduce trauma to the maxillary denture bearing area

Answer 4

maximise coverage of the denture bearing area by prosthesis
ensure prosthesis covers the primary load bearing sites

Question 5

how to optimise loading of the denture bearing area?

Answer 5

use over dentureabutments

Question 6

how to ensure stability of the maxillary denture

Answer 6

optimum border seal
effective post dam
