Implant Fixture
The threaded titanium or zirconia body that is surgically inserted into the jawbone to serve as the root-like foundation of a dental implant.
Full Definition
The implant fixture—also called the implant body or endosseous implant—is the component placed directly into prepared bone during the surgical phase of implant treatment. It is typically screw-shaped and made of commercially pure titanium or titanium alloy (Ti-6Al-4V), though zirconia fixtures are increasingly documented in the literature. Editors must distinguish it from the abutment (the connector above the gumline) and the crown (the visible prosthetic tooth). The term 'fixture' is preferred in European literature, while 'implant body' appears more frequently in North American journals.
Usage
Usage note: In North American publications, 'implant body' is preferred; in European publications, 'fixture' is standard. Editors should flag inconsistencies within a single document.
