Analysis of the properties of silicone rubber maxillofacial prosthetic materials [PDF]
Journal of Dentistry, 2003 Maxillofacial prosthetic materials are used to replace facial parts lost through disease or trauma. Silicone rubbers are the materials of choice, however it is widely accepted that these materials do not possess ideal properties. The objective of this study was to assess the properties of a range of commercially available silicone rubber maxillofacial ...

Evaluation of Various Reinforcements for Maxillofacial Silicone Elastomers
Journal of Biomaterials Applications, 1994Various 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 ...

Light-weight RTV silicone for maxillofacial prostheses
The Journal of Prosthetic Dentistry, 1976Weight is a problem in retention of large skin-textured maxillofacial prostheses. The purpose of this investigation was to test the feasibility of mixing foam RTV silicone rubber with conventional RTV silicone rubber to obtain a light-weight material.

The use of RTV silicones in maxillofacial prosthetics
The Journal of Prosthetic Dentistry, 1970Abstract The silicones may be used for practically any restoration of tissue and may be cemented to hard acrylic resin where necessary. The advantages include the physical properties of chemical inertness, thermal and dimensional stability, elasticity, flexibility, and skin-like texture.

Use of thermochromic pigment in maxillofacial silicone elastomer
The Journal of Prosthetic Dentistry, 2013Silicone 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 ...

Influence of pigments and opacifiers on color stability of silicone maxillofacial elastomer
Journal of Dentistry, 2009To determine the effects of opacifiers and silicone pigments on the color stability of silicone A-2000 maxillofacial prosthetic elastomers subjected to artificial aging.Seventy-five groups (n=5) were made by various combinations (5%, 10%, and 15%) of four dry earth opacifiers (Georgia kaolin, Gk; calcined kaolin, Ck; Artskin white, Aw; titanium white ...

Effect of nano-oxides on the color stability of maxillofacial silicone elastomers
The Journal of Prosthetic Dentistry, 2022A significant challenge of craniofacial prostheses is their limited service life because of degradation and color instability. In spite of improvements in the materials and techniques used for the fabrication of silicone maxillofacial prostheses, undesirable color change over time remains a challenge.

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 ...

Adhesive retention of silicone and chlorinated polyethylene for maxillofacial prostheses
The Journal of Prosthetic Dentistry, 2008A key factor of a successful facial prosthesis is the retention of the prosthesis to the patient's skin, especially when there is no mechanical means and the retention depends primarily on medical skin adhesives. Studies determining which medical adhesives provide the best bond strength for maxillofacial prostheses are needed.The purpose of this study ...

Properties of Maxillofacial Silicone Elastomers Reinforced with Silica Powder
Journal of Biomaterials Applications, 1998Compounds of a silicone elastomer suitable for preparing maxillo-facial prostheses, reinforced with various amounts of silica powder, have been studied for their mechanical response and wetting properties in terms of contact angle. Tensile strength and elongation at break showed an increase with increasing silica volume fraction up to 35%, whereas the
