Why aluminium for biomedical implants?<\/h3>\r\n\r\n\r\n\r\n

Aluminum a low-cost, light-weight metal that\u2019s in many different industries for a variety of different products. There are a number of reasons why this makes aluminium a great choice for medical implants.<\/p>\r\n\r\n\r\n\r\n

Biocompatibility<\/strong> – Aluminum is biocompatible, which means that it\u2019s safe to use in a biomedical application like an implant. It doesn\u2019t trigger an immune response, so it\u2019s unlikely to cause any unwanted side effects.<\/p>\r\n\r\n\r\n\r\n

Corrosion resistance<\/strong> – Aluminum has excellent corrosion resistance. This means that it\u2019s unlikely to react with the human body fluids, which could cause damage to surrounding tissue. It\u2019s also unlikely to corrode and cause damage to surrounding implants.<\/p>\r\n\r\n\r\n

Low strength <\/strong>– Aluminum also has low strength. This means that it\u2019s unlikely to cause injury to surrounding tissue.<\/p>\r\n\r\n\r\n\r\n

Low density<\/strong> – Aluminum has a low density, which means that it\u2019s lightweight. This makes it a safe option for implants in sensitive areas like the brain.<\/p>\r\n\r\n\r\n\r\n

We at Royal Dental prefer using Titanium based or Zirconia based dental implant, as the research on aluminium dental implants is low when compared with Titanium based.\u00a0<\/strong><\/p>\r\n\r\n\r\n\r\n

But why isn\u2019t all aluminium safe as biomedical implants?<\/h3>\r\n\r\n\r\n\r\n

Unfortunately, all aluminum not created equal. Alloys are mixtures of different metals, which together to make a single material for a specific application. Aluminum alloys commonly used for biomedical implants, but not all of them safe for this purpose.<\/p>\r\n\r\n\r\n\r\n

There are a few factors to consider when choosing a suitable alloy for biomedical implants. The most important factor is the solubility of the metal<\/strong>. As we\u2019ve seen above, all aluminum is biocompatible, but not all of it is safe for use in biomedical implants. To be safe for use in biomedical implants<\/a>, the aluminum alloy needs to be resistant to corrosion. The metal needs present in a form that dissolved by body fluids. Aluminium alloys that are low in silicon are more likely to be safe for use in biomedical implants.<\/p>\r\n\r\n\r\n\r\n

Types of aluminium that aren\u2019t safe for use in biomedical implants?<\/h3>\r\n\r\n\r\n\r\n

Let\u2019s take a look at some of the commonly used aluminium alloys that aren\u2019t safe for use in biomedical implants.<\/p>\r\n\r\n\r\n\r\n

1100-O19<\/strong> – This is one of the most commonly aluminum alloys for biomedical implants. Unfortunately, it\u2019s not suitable for use in biomedical applications because it contains zirconium, which is highly soluble in water. If this alloy used in a biomedical implant, it\u2019s likely to dissolve and cause damage to the surrounding tissues.<\/p>\r\n\r\n\r\n

2024-T3<\/strong> – This alloy used in aircraft engineering for its biocompatibility. However, it\u2019s likely to cause corrosion in a biomedical implant, which can damage the surrounding tissues. 2024-T3 is also likely to cause stress corrosion cracking, which can lead to implant failure.<\/p>\r\n\r\n\r\n\r\n

6061-T6<\/strong> – This is very common in the biomedical industry due to its low cost. Unfortunately, it\u2019s likely to cause corrosion in a biomedical implant, which can damage the surrounding tissues.<\/p>\r\n\r\n\r\n\r\n

We at Royal Dental prefer using Titanium based or Zirconia based dental implant, as the research on aluminium dental implants is low when compared with Titanium based.\u00a0<\/strong><\/p>\r\n\r\n\r\n\r\n

Which types of aluminum are safe for use in biomedical implants?<\/h3>\r\n\r\n\r\n\r\n

Now that we\u2019ve covered some of the commonly used aluminium alloys that aren\u2019t safe for use in biomedical implants<\/a>, let\u2019s take a look at some of the alloys that are.<\/p>\r\n\r\n\r\n\r\n

2024-T4<\/strong> – Same as the same as 2024-T3, but it has different silicon content. The silicon in this alloy is likely to prevent corrosion in a biomedical implant. This makes it a safe option for biomedical implants.<\/p>\r\n\r\n\r\n\r\n

2024-T6<\/strong> – This is the same as 2024-T3, but it has a higher silicon content. This makes it more resistant to corrosion in a biomedical implant. The silicon in this alloy is likely to prevent corrosion, but it may also be likely to cause stress corrosion cracking.<\/p>\r\n\r\n\r\n\r\n

6061-T5<\/strong> – It is the same as 6061-T6, but it has a different silicon content. The silicon in this alloy is likely to prevent corrosion in a biomedical implant. This makes it a safe option for biomedical implants.<\/p>\r\n\r\n\r\n\r\n

What to know before using aluminium in implantable devices?<\/h3>\r\n\r\n\r\n\r\n

Aluminum is a great option for biomedical implants, but it\u2019s important to choose the right kind of alloy for the job. Aluminum alloys with low silicon content are likely to be safe for use in biomedical implants. It\u2019s important to check the silicon content in the alloy, and to also check that it\u2019s corrosion resistant. When choosing an aluminium alloy for a biomedical implant, it\u2019s important to understand how it\u2019s going to be used.<\/p>\r\n\r\n\r\n\r\n

Biocompatible aluminum alloys are likely to cause very little damage to the surrounding tissue. However, if the implant is in an area that\u2019s regularly moved, like the knee joint, it\u2019s important to consider how that might affect the surrounding tissue.<\/p>\r\n\r\n\r\n\r\n

We at Royal Dental prefer using Titanium based or Zirconia based dental implant, as the research on aluminium dental implants is low when compared with Titanium based.\u00a0<\/strong><\/em><\/h5>\r\n\r\n\r\n\r\n

An implant that\u2019s not properly fitted or is severely broken can cause damage to the surrounding tissue. Aluminium is likely to cause minimal damage, but there\u2019s a risk that it could lead to an infection if the implant breaks.<\/p>\r\n\r\n\r\n\r\n

If an implant is in a high-risk area like the brain, it\u2019s likely to be surgically removed as soon as possible. This is likely to cause damage to the surrounding tissues, but it\u2019s important to remove the implant as quickly as possible to prevent serious damage.<\/p>\r\n\r\n\r\n\r\n

Conclusion to biomedical implants<\/h3>\r\n\r\n\r\n\r\n

Aluminum is a good choice for biomedical implants, but the type of aluminum alloy that\u2019s used is important. Aluminum alloys with low silicon content are likely to be safe for use in biomedical implants. It\u2019s important to check the silicon content in the alloy, and to also check that it\u2019s corrosion resistant.<\/p>\r\n\r\n\r\n\r\n

An implant that\u2019s not properly fitted or is severely broken can cause damage to the surrounding tissue. If the implant is in a high-risk area like the brain, it\u2019s likely to be surgically removed as soon as possible.<\/p>\r\n\r\n\r\n\r\n
