Cover screws, also known as closure screws, are devices used to seal the internal cavity of implants after implantation to prevent external contaminants from entering. Its main function is to protect the sterile environment of implants during the healing process and ensure the successful fusion of implants.

Material and shape: Cover screws are made of titanium alloy or biocompatible materials, and are mostly threaded in shape to ensure a close fit to the internal cavity of the implant to prevent external contamination.

Advantages
Protecting the sterile environment: Cover screws can prevent external contaminants from entering the implant and ensure the sterile environment of the implant.
Simplifying the surgical process: By installing cover screws, doctors can simplify the surgical process and reduce the time and complexity of the operation.
Reduce the risk of complications: Protecting the sterile environment of the implant helps reduce the risk of complications such as infection and inflammation.
