Estimation Of Color Change Of Maxillofacial Silicone Elastomer After Artificial Aging

Mustansiria Dental Journal, 2022
Background: Silicone elastomers are the most widely used maxillofacial materials, however, it is far away from ideal and still progresses through many improvements for replacing the facial defect, maxillofacial prostheses need renewed as early as six months and can last up to 24 months.

Effect of Time Passage on Some Physical Properties of Silicone Maxillofacial Elastomers

Journal of Craniofacial Surgery, 2011
Changes in color and other physical properties of silicone facial prosthesis are the main reasons for its replacement. The purpose of this study was to investigate the effect of time passage on some physical properties such as tensile strength, modulus of elasticity, elongation at break, tear strength, hardness, color stability, and contrast ratio (CR)
