“…UV irradiation can contribute to enhancing cross linking leading to breaking down of chain bonds and decomposing of elastomer. 22 The samples subjected to artificial perspiration showed least colour change when compared to the samples subjected to the cleansing agent. This was not in agreement to a study by Hatamleh 22 which showed that the antimicrobial cleansing agent produces the least colour change when compared to acidic perspiration.…”

“…This study has utilized accelerated ageing, artificial perspiration and a cleansing agent for simulating photo-chemical insult to the silicone. Ageing parameters for accelerated weathering in a chamber, use of artificial perspiration and cleansing agent were based on protocols followed by Hatamleh et al 22 and Eleni et al 26 Artificial perspiration solution was obtained by following the methodology described by Hatamleh et al 22 and Polyzois et al. 24 Such a solution has been used as a standard for exposure of the silicone elastomer samples to simulated body fluids.…”

“…Studies by Gary et al 21 and Hatamleh et al 22 have shown that the change in colour has been attributed to the degradation in the elastomer itself. Hence, the first strategy towards increasing the longevity of prostheses by reducing its colour change should be towards improving colour stability of the silicone elastomer itself.…”

Past, Present, and Future of Soft‐Tissue Prosthetics: Advanced Polymers and Advanced Manufacturing

past 30 years, [12,13] it is only the last decade that has seen its rapid development as part of the fourth industrial revolution. [14] This change in practice is evidenced by the significant fraction of recent literature describing advances in 3D printed prostheses, including technological advances [4,15-18] and clinical reports. [19,20] Further innovations involving collaborations between clinicians, academics, and industry, promise even greater capabilities. The future will see 3D printers that can mix materials as desired during fabrication [21] and those that can 3D print organic semiconductors and piezoelectric polymers for sensing and bionics [22-24] (Figure 1). This report is focused on polymers for soft tissue, external, personalized, prosthetics with clinical applications for the ear, [25] nose, [26] eye, [27] face, [28] breast, [29] and hand. [30] The characteristics of both traditional and 3D printable polymeric materials, as well as current advanced manufacturing technologies and those in development, are also reviewed. The earliest evidence of prosthetics dates back to ≈2300 BC, where Egyptian mummies have been discovered with eye, nose, and genital reconstructions fashioned from plaster packed with mud, sand, linen, butter, or soda (Figure 1). [31] Wood, cloth, natural waxes, resins, and metals were later used as the material of choice for rudimentary prostheses. [32] Prostheses remained relatively unchanged for thousands of years until the 16th century, where prosthetic noses and eyes were made from parchment, wax, wood, hard rubber, gold, silver, and copper. [33] Metals continued as a fundamental material throughout the 19th century, largely due to their ability to be shaped and molded as needed. [34,35] One of the first polymers to be used in prosthetics, poly(methyl methacrylate) (PMMA), was developed in response to the glass shortages in the World Wars of the 20th Century. [36] This polymer went on to become the most common prosthetic material of the time, and still finds use today in artificial eyes [33] and prosthetic substructures. [37] Further innovations in the 20th century produced many new polymers, such as vinyls, copolymers, plastisols, and one of the most significant materials in prosthetics, silicone. [38] Discovered in the early 1900s by Fredrick Kipping, silicone was first used in prosthetics by George W Barnhart in 1960. [39] This versatile polymer remains a primary prosthetic material today due to its soft tissue-like properties, ease of manipulation, chemical inertness, durability, and excellent biocompatibility. [40,41] The search for alternative materials Millions of people worldwide experience disfigurement due to cancers, congenital defects, or trauma, leading to significant psychological, social, and economic disadvantage. Prosthetics aim to reduce their suffering by restoring aesthetics and function using synthetic materials that mimic the characteristics of native tissue. In the 1900s, natural materials used for thousands of years in prosthetics were replaced by syntheti...
