In Vitro Cytotoxicity of Maxillofacial Silicone Elastomers: Effect of Nano‐particles
Journal of Prosthodontics, 2016AbstractPurposeSilicone elastomers are generally used for maxillofacial extraoral prostheses. The purpose of this in vitro study was to evaluate the cytotoxicity of different kinds of nanoparticles added to two types of maxillofacial elastomers.Materials and MethodsA‐2000 and A‐2006 silicone elastomers were used.

Maxillofacial Silicone Elastomers in Dentistry
2020Maxillofacial prostheses are used for patients with deformities in the maxillofacial area induced by cancer, trauma or congenital defects. Different types of polymers are used in the manufacture of maxillofacial prosthesis. However, silicone elastomers are the polymers most commonly used in the maxillofacial prosthodontics because of their acceptable ...

Characterization of maxillofacial silicone elastomer reinforced with different hollow microspheres
Journal of Materials Science, 2015The composition and properties of silicone–hollow microsphere composites were studied in view of establishing a new type of maxillofacial prosthesis material. Two types of microspheres were used in different concentrations and were well dispersed in the silicone matrix. The mechanical properties of the composites were evaluated.

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

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.

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.
