Background Dental implant placement navigation systems based on optical tracking have been widely used in clinics. However, electromagnetic (EM) navigation method that does not suffer from problems of hidden line‐of‐light has not yet been described. Methods This work proposes an EM‐guided navigation method named TianShu‐ESNS with virtual calibration. Model (12 implants) and animal experiments (pig head: six implants) were conducted to evaluate its performance and stability. Result The mean virtual calibration error was 0.83 ± 0.20 mm. The mean deviations at the entry point, end point and angle in the phantom experiment of TianShu‐ESNS were 1.23 ± 0.17 mm, 1.59 ± 0.20 mm and 1.83 ± 0.27°, respectively. In the animal experiment, the same deviations were 1.25 ± 0.07 mm, 1.57 ± 0.35 mm and 1.90 ± 0.60°, respectively. Conclusions The experimental results show that TianShu‐ESNS with the virtual calibration method could serve as a promising tool to eliminate the line‐of‐light hidden problem and simplify operation procedure in dental implant placement.

“…It was expressed that further research is needed for implant design which must include TMJ components and their materials' ability to withstand high concentration stresses, under severe or maximum loading conditions. According to Memon et al 7) , it is imperative to conduct finite element analysis of prosthesis and implants which can reflect on complex geometry of implant and its biomechanical properties. Antic et al 8) presented a brief study on morphology pf bone and muscle action in human jaw, which can be useful in implant design and analysis.…”

The stress concentration for a unique temporomandibular joint prosthesis was evaluated using finite element analysis in the present work. This study intended to validate temporomandibular joint prosthesis design specific to Asian population. Total joint replacement is a complicated procedure and surgery can cause numerous complications such as hardware failure, cleft, contamination or facial immobility. Hence, it is imperative to study stresses acting during jaw movement. A three-dimensional static structural finite element approach was followed. The study reflects on even stress distribution, with least detrimental effects to human natural joint. Thus, the design efficiency is validated and also helped in analysing medical ramifications for actual temporomandibular joint surgery.

“…Available software includes engineering-based computer aided design packages (CAD), [94] or polygon-based computer modeling software designed for freeform medical modeling, movies, and animations. [3,[95][96][97] In some applications, advanced modeling software can automate parts of the prosthetic design process, [98] and even simulate mechanical properties prior to fabrication using finite element analysis. [27] The final digital model is then fabricated using computer aided manufacturing approaches; using either subtractive milling methods [99] or advanced manufacturing approaches, such as 3D printing.…”

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...
