“…Shetty 8) studied the effect of primers on maxillofacial silicon and three types of surface-characterized acrylic resin, concluding that primers were more compatible with silicone elastomer and also that the presence of retentive holes increased bond strength. Haddad 14) et al also reported that primer use increased bond strength between autopolymerized acrylic resin and facial silicone elastomer. Therefore, primer use on an acrylic plate is generally considered to be conducive to silicone elastomer bonding.…”

“…Unifast is used for temporary prostheses, denture repair 23) , and attaching housing to the facial prostheses 9) . The bonding of silicone on an acrylic plate was reported very poor when bonded without a primer 8,14,24) . Therefore, the bond strength between silicone and acrylic without a primer was not examined.…”

“…Plasticbond is used as the primer for facial silicone plus acrylic resin, and Sofreliner primer was originally developed to modify denture base acrylic surfaces for silicone denture relining. It has been reported that the use of Sofreliner primer increases the bond strength between facial silicone elastomer and autopolymerized acrylic resin 14) . The metal flask mold process is usually used for making small prostheses and mainly used for in vitro cases 15) , while the flaskless stone mold process is commonly used for fabricating larger or more complicated prostheses 5) .…”

“…However, delamination of maxillofacial silicone elastomer from contact with the acrylic resin can be problematic in such facial prostheses 9,10) . Therefore, the bonding process between silicone elastomer and acrylic resin has been investigated 9,[11][12][13][14] , and the use of a primer has been suggested to obtain suitable bond strength. Moreover, the type of fabrication process for facial prostheses is also considered to influence the bonding.…”

This study evaluated the effects of the fabrication process on tensile bond strength between maxillofacial silicone elastomer and acrylic resin. A common maxillofacial silicone elastomer (VST-50), two primers (Sofreliner primer and R-SI-LINE Plasticbond), and two acrylic resins (Unifast III and Palapress Vario) were selected. Silicone elastomer between primed acrylic resin plates were polymerized using a metal flask mold or a flaskless stone mold. Bond strength of the specimens was measured by a tensile test and analyzed using two-way analysis of variance (ANOVA) with Tukey's honest significant difference test. All fracture surfaces showed interfacial fracture. Both the fabrication process and the primer-acrylic resin combination affected bond strength, and two-way ANOVA indicated a significant interaction. Bond strength was generally greater when silicone elastomer was polymerized using a flaskless stone mold.

“…They used different primers and surface modification (scratch) to check the effect of bond strength and concluded that use of primer increased the bond strength but use of primer along with the surface modification (scratch) has weakened the bond strength between silicone elastomer and acrylic [14].…”

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...
