1
Q
what are relines and their types
A
- Relines are carried out when the fitting surface is inadequate, denture loose fitting but teeth aren’t worn and in good condition – new base material is added to the fitting surface to fill the space which exists between the original denture contour and the altered tissue contour
o Temporary – grossly ill-fitting dentures, immediate denture, after implant surgery
o Soft – useful for parafunctional habits, atrophic ridges and cancer/cleft patients (obturators)
o Permanent – heat-cure acrylic, useful in peripheral seal problems, prolongs lifespan of denture

Q
technique for reline
A
- Technique:
o Remove undercuts from denture fitting surface using acrylic bur
o If denture is underextended, extend with greenstick
o Apply appropriate adhesive to fitting surface of denture
o Impression with light body PVS taken in fitting surface using closed mouth technique
o Remove imp, examine, disinfect and send to lab with lab prescription
Please pour reline impression in 100% dental stone. Please provide reline of fitting surface in heat-cure PMMA
o Bring pt back for fit and review in 2 weeks - Pt must be happy to go without denture whilst being relined
- Rebase is when the entire denture base material is replaced whilst keeping the teeth
