We evaluated the influence of chemical disinfection and accelerated aging on the dimensional stability and detail reproduction of a silicone elastomer containing an opacifier and/or a pigment. A total of 120 samples were fabricated from Silastic MDX 4-4210 silicone and divided into groups (n = 10) according to pigment and/or opacifier (ceramic powder ...

Little information exists on the biocompatibility of maxillofacial prosthetic materials. Cosmesil material is a purpose-designed facial prosthetic elastomer that has an established clinical profile in humans but results of biocompatibility testing have not been published. Cosmesil, acrylic resin (positive control), black surgical gutta-percha (negative

Colour stability of maxillofacial silicone elastomers: a review of the literature.
The European journal of prosthodontics and restorative dentistry, 2015Colour degradation is a serious limitation of maxillofacial silicone elastomers and most silicone facial prostheses have to be remade within 1 year due to colour deterioration. A comprehensive review of the literature was completed using MEDLINE and PubMed Library databases. This was supplemented with a manual search of selected journals and textbooks.

Adhesion of maxillofacial silicone elastomer to a fiber-reinforced composite resin framework.
The International journal of prosthodontics, 2011Recently, fiber-reinforced composite resin (FRC) has been introduced as a framework material for maxillofacial silicone prostheses. The purpose of this research was to study the tensile bond strength between a room temperature-polymerized maxillofacial silicone elastomer and a unidirectional FRC.Three different bonding agents were compared.

Silicone elastomers are becoming more readily available for additive manufacturing, which may be advantageous for fabricating maxillofacial prostheses. However, the properties of three-dimensionally (3D) printed silicone as compared with conventionally processed silicone have not been well studied.The purpose of this in vitro study was to compare the ...
