A NEW TEMPORARY SOFT LINING MATERIAL

The viscoelastic properties of a new light-activated temporary denture soft lining material have been monitored in vitro using a force/dista nce probe. Its baseline behaviour was characteristic of an elastic mat erial and its compliance considerably less than that of both a short-t erm and a long-term soft lining material which were used as controls. Sample thickness had no appreciable effect on this compliance. These r esults suggest that the new product is likely to be perceived as being significantly harder by a patient. Twenty-four weeks' immersion in di stilled water had no significant effect on either the compliance or el asticity of the test material and would suggest an improved durability when compared to other conventional short-term resilient denture lini ng materials, albeit at the expense of compliance.
