Hollow basket implant

A hollow basket implant, also called a hollow cylinder implant system, was created in the late 1970s at the Straumann Institute in Waldenberg, Switzerland. Its design differs greatly from a traditional screw implant in that the implant hardware is not solid but rather crafted to be hollow, with small holes or perforations throughout the implant. The hollow basket implant design allows for almost double the contact with bone compared to a solid cylinder implant, minimizing bone destruction and promoting the fusion of bone to implant, also known as osseointegration. The design also minimizes stress to the implant when during vertical loading. The perforations in the cylinder allow for bone to grow through the implant and fill the hollow spaces, versus simply adhering to the outside of a textured solid implant screw. This provides added stability and permanency. Typically, hollow basket implants are created with a commercially pure titanium metal or titanium alloy to promote osseointegration.
