True or false: rebasing a denture can lead to an increase in OVD
During a chairside soft reline procedure, the setting reaction of the material is:
The aromatic ester in the liquid part of a soft chairside reline material is a...
Long term soft liners are made of one of two materials: Silicone and Acrylic.
Silicone materials can be either [blank_start]cold[blank_end] curing or [blank_start]heat[blank_end] curing. Acrylic long term soft liners are [blank_start]heat[blank_end] cured - cold cured acrylics are only suitable for very [blank_start]short[blank_end] term linings and tissue [blank_start]conditioning[blank_end].
Cold curing silicone materials contain filler. As the level of filler rises, so does the level of [blank_start]water sorption[blank_end] and worsening of dimensional stability. The material is liable to [blank_start]tear[blank_end] and detach from the denture base. The [blank_start]abrasion[blank_end] resistance are poor.
Heat curing silicone materials have lower levels of water sorption. [blank_start]Dimensional[blank_end] stability is therefore higher and the [blank_start]adhesion[blank_end] to the denture base is better.
Long term soft acrylic linings contain either poly[blank_start]ethyl[blank_end]methacrylate or poly[blank_start]butyl[blank_end]methacrylate polymers and are heavily p[blank_start]lasticised[blank_end] to create softness.
