Can Special titanium alloy let implants fight off bacterial infections?

Is titanium safe in your body?

It is not considered a toxic metal but it is a heavy metal and it does have serious negative health effects. Titanium has the ability to affect lung function causing lung diseases such as pleural disease, it can cause chest pain with tightness, breathing difficulties, coughing, irritation of the skin or eyes

 

Is titanium better than bones?

Despite being erosion-resistant and incredibly strong, titanium plates can lead to bone embrittlement once bones are healed as they are significantly more rigid than bones.

Does bone grow over titanium plates?

Titanium is a fairly soft metal that has the unique property of being biocompatible, that is, it does not cause a foreign body reaction to bone. In fact, after some time, bone cells adhere directly to titanium, without the need to interpose a fibrous layer between them, as happens with other types of metal implants.

What are the benefits of titanium in the human body?

While implanting titanium materials such as artificial buttocks can greatly improve patients' lives, they can also suffer from severe bacterial infections. However, an experimental novel antibacterial titanium alloy may make such problems a thing a thing of the past. In recent years, many research groups have developed antibacterial coatings that can be applied to titanium implants. While some jackets show hope, they may disappear over time. It was developed by scientists at Washington State University and consists primarily of a traditional titanium alloy, but also contains 3% copper and 10% tantalum, the latter of which is a corrosion-resistant metal.

 

When almost any artificial object is implanted into the body, harmful bacteria have the potential to colonize their surfaces and surrounding tissues. Microorganisms continue to form a viscous coating called biofilms, which is resistant to antibiotics. Therefore, a second surgery is sometimes required to clean and disinfect the implant.

In recent years, various research groups have developed antibacterial coatings that can be applied to titanium implants. Although some of these coatings have indeed shown promise, they may fade over time. Moreover, applying them to implants only adds a step to the production process. That's where the new 3D-printable material comes in.

This is where the new 3D printing material comes into play.

When bacteria come into contact with the material, copper causes their outer membrane to rupture, killing most of the bacteria in it. Meanwhile, tantalum promotes the growth of adjacent bone tissue. This factor speeds up the healing process and shortens the time span of infections-and of course, it can also allow patients to stand up faster.

In tests performed on laboratory rats, implants made from the alloy were found to kill 87% of infectious Staphylococcus aureus upon contact. Scientists are now working to increase that number to more than 99%, and in addition, they are evaluating how affordable the implants made from the material can be in actual use.
