“…Pure silver is soft and not wear-resistant; its corrosion resistance is not as good as that of the gold alloy. It is easy to change color and lose color in the oral cavity [63], but it has a low price and good processing and casting performance. Thus, the silver alloy like Ag-Pd and Ag-Cu-Pd-Au formed by compounding with other precious metals can be used as crowns, bridges, and inlays, etc.…”

Metals have been used for orthopedic implants for a long time due to their excellent mechanical properties. With the rapid development of additive manufacturing (AM) technology, studying customized implants with complex microstructures for patients has become a trend of various bone defect repair. A superior customized implant should have good biocompatibility and mechanical properties matching the defect bone. To meet the performance requirements of implants, this paper introduces the biomedical metallic materials currently applied to orthopedic implants from the design to manufacture, elaborates the structure design and surface modification of the orthopedic implant. By selecting the appropriate implant material and processing method, optimizing the implant structure and modifying the surface can ensure the performance requirements of the implant. Finally, this paper discusses the future development trend of the orthopedic implant.

“…Nickel in metal alloys was used in dentistry and orthodontics as well due to their exceptional mechanical properties. Orthodontic materials including archwires, brackets and molar bands are made from stainless steel containing approximately 8 to 12% nickel (Givan et al, 2014); (Proffit et al, 2007). The addition of nickel enhances the corrosion resistance and ductility properties of the stainless steel alloy.…”

Objective: Prolonged nickel exposure, even in low amounts, is cytotoxic, genotoxic and carcinogenic. The study aims to evaluate the salivary and urinary nickel levels post-orthodontic fixed appliance treatment. Materials and Methods: Saliva and urine samples of fourteen orthodontic patients were taken at debonding (T0), after one month (T1), and three months post-debonding (T2), and compared with the control group. Samples were analysed using Inductively Coupled Plasma Optical Mass Spectrometry (ICP-MS) and IBM SPSS Version 27 was used for statistical analyses. Results: The mean (SD) of orthodontic treatment duration was 33.6 (9.6) months. In comparison to the control group, the mean (SD) nickel levels in saliva and urine were highest at debonding (T0) with 12.71 ppb (9.64) and 9.71 ppb (8.27), respectively. In the test group, there was a significant difference in nickel level in saliva between T0 and T1 (MD = 9.75, 95% CI: 3.71, 15.71; p < 0.05) and in urine between T0 and T1 (MD = 6.46, 95% CI: 1.38, 11.55; p = 0.012). Conclusion: Our results clearly demonstrated that the nickel level in saliva and urine remained higher at the end of orthodontic treatment compared to the control group. Further studies with a longer duration of observation and larger samples are suggested. Furthermore, our study indicates it is essential to confirm the effects of long-duration of orthodontic treatment and its post-treatment nickel level. This study raised attention about the biocompatibility of mechanical orthodontic treatment vs sustainable general health.

Objectives: Nickel is one of the common trace metal element used in industries. It has been documented that even in small quantities, prolonged exposure to nickel is cytotoxic, genotoxic and carcinogenic. Nickel biomonitoring has been done by various countries to monitor nickel level. However, there is little information on established baseline nickel level in our population which leads to the difficulty for comparison during nickel exposure. This study aims to determine the baseline nickel level in saliva and urine samples for the healthy Malay population. Materials and Methods: Fourteen healthy Malay subjects were recruited in this study. Saliva and urine samples were collected and analysed using Inductively Coupled Plasma Optical Mass Spectrometry (ICP-MS) to measure the nickel level. Statistical analysis was performed using IBM SPSS Version 27. Results: Results showed that the nickel level in urine was higher compared to saliva. The baseline nickel level exhibited in saliva was 4.80 ppb (95% CI: 2.23, 7.38) and in urine was 5.88 ppb (95% CI: 3.49, 8.27). Conclusion: To our knowledge, this is the first study to report the baseline nickel level in saliva and urine among the Malay population.
