moist environment
When do we have check up appointments for denture placement?

- after 2-3 years
What are the types of relines?
Direct and indirect
What is a direct reline? (2)
◦ An acrylic resin is used right into the mouth.
◦ No need to send the denture to the lab.
What is an indirect reline? (2)
◦ An impression is taken with the denture (denture works as a tray).
◦ It ́s sent to the lab so the impression material is replaced by acrylic resin.
What materials are used for indirect relines? (4)
- Zinquenolic paste.
- Light body silicone.
◦ Heat-curing resin (best option).
◦ Self-curing resin.
What materials are used for direct relines?
Hard self curing acrylic reline materials
What do we do if there is inflammation at the supporting tissues and we need a reline? (2)
- use soft reline elastic materials (soft tissue conditioners) for 2-3 weeks
- then do a hard reline
Indirect reline techniques? (2)
◦ Flasking.
◦ Direct placement of resin.
What do we do if theres a base fracture and we need to reline?
send to lab

- psychological, vit A/iron deficiency, drugs producing xerostomy, allergies
Denture failures: ulcers cause? (2)
◦ Overextended borders.
◦ Occlusion.
Denture failures: masticatory abilities? (2)
Check:
- occlusion
- VD
Denture failures: Talking alterations?
High VD
Denture failures: frequent dislodgement? (2)
- Due to unsuitable residual ridges » implants.
- Misfit of the denture (possible need for a reline).
Denture failures: Persistent nausea? (2)
