Evaluation of Various Reinforcements for Maxillofacial Silicone Elastomers

Journal of Biomaterials Applications, 1994
Various reinforcements have been evaluated according to their effect on the mechanical properties of a silicone elastomer used for the preparation of maxillofacial prosthetic compositions. Emphasis was given to silica reinforcing fillers since fibrillar reinforcements [e.g., short aramid, glass or high modulus polyethylene (UHMPE)] seemed not to ...

Use of thermochromic pigment in maxillofacial silicone elastomer

The Journal of Prosthetic Dentistry, 2013
Silicone elastomers are used to fabricate external maxillofacial prostheses and are colored to match the adjacent facial skin. In cold winter weather, in certain individuals, the color of the skin changes toward red, which leads to a color difference between the prostheses and the surrounding tissue.The purpose of this study was to study the use of a ...
