Medical implants are used to monitor or treat health conditions. They can also be used to restore certain bodily functions. Medical implants are attached to the skin or placed inside a patient’s body – on a temporary or permanent basis.
The use of medical implants comes with some risks, like bleeding, infection, or implant failure. This usually occurs during the placement or removal of the implant.
Thankfully, oxygen plasma cleaning is doing well to address some of the shortcomings of medical implants. One way it’s doing that is by improving the adhesion in medical implants.
Therefore, this article examines how oxygen plasma cleaning improves medical implants’ quality and reliability through enhanced bonding.
Importance of Adhesion in Medical Implants
Knowing how important adhesion is in medical implants is essential because it affects their stability, lifespan, and ability to help the body heal properly.
Why Adhesion Matters
Adhesion is critical in medical implants to prevent complications that can ruin how implants function. Proper adhesion can prevent issues such as scarring that interfere with medical device’s functions.
Scarring occurs when scar tissue builds up in the system. This is usually the handiwork of the body’s immune system reacting against a medical implant.
A strong bonding ensures the durability and functionality of coatings (e.g., anti-bacterial, biocompatible, or drug-eluting).
Medical implants are coated with adhesive biomaterials that are non-reactive to surrounding body tissues. This ensures the implants are biocompatible with the patient’s biology.
Common Adhesion Challenges
Untreated medical implants do not guarantee effective adhesion for most bonding and coating applications.
They have common adhesion challenges that limit them from forming strong bonds with other materials. This can result in severe quality issues for various medical procedures.
Some of the boding issues exhibited by medical implants can be attributed to surface contamination, low surface energy, or material compatibility issues.
Impact on Patient Safety
From anti-bacterial to adhesive biomaterials, adequate adhesion is necessary to ensure that medical implants work seamlessly with human biology.
Failure of adhesion can lead to complications like coating delamination or implant rejection. This can pose great risks to patients.
How Oxygen Plasma Cleaning Works for Medical Implants
