1. Wright PS. in 1984 stated that there is sufficient evidence available for use of soft liner but because of its inadequate physical properties the use of soft liner is limited. The objectives of the study were:
1. Clinical success of the available soft liner material and their retrospective study.
2. The collection and measurement of data relating to a group of wearing soft-lined mandibular dentures for edentulous patients.
3. A three year longitudinal study of the clinical success of both available and new soft-lining materials.
He investigated soft liner material for 18 months and concluded that soft liner provided comfort to patients. They considered soft liner as a successful material but still it wasn’t give satisfactory clinical results. …show more content…
Nimmo A., Fong BJ., Hoover CI., Newbrun E. in 1985 evaluated tissue-conditioning materials are used to improve the health of inflamed denture-bearing tissues and also use to make functional impressions for reline procedures. For both of these uses, a uniform mix with minimal air incorporation in the tissue conditioner is desirable. If the air incorporated it produces voids in the material and these voids are undesirable for several reasons. When material used as a tissue-conditioning material, voids may provide shelter for debris and bacteria that will irritate the tissue. Due to voids inaccuracy in the functional impression occurs. Vacuum treatment of tissue-conditioning material provide solution to the problem of voids in the material. Vacuum-mixing is widely used to reduce the entrapment of air in gypsum products. The purposes of this study were to determine (1) reduction of void formation in tissue-conditioning material with use of vacuum treatment and (2) effect of microbial adherence on material with use of vacuum …show more content…
Kawano F., Tada N., Nagao K., Matsumoto N. in 1991 evaluated that several soft lining materials are available which differ in physical and mechanical properties. The properties of soft lining materials were investigated by using various tests like static creep test and a pressure distribution test. Six typical soft lining materials were used. On soft lining materials the pressure on the testing plate were equally distributed. For external forces soft lining material act as a cushion. However, the variation of pressures increased in cases of Hydro-cast and Softone materials, but decreased in case of Coe-comfort
