What is a titanium implant post?
A titanium implant post is the screw-shaped metal fixture surgically placed into the jawbone to serve as an artificial tooth root and support a dental prosthetic.
The titanium implant post, also called a fixture or endosseous implant, is a small cylindrical screw typically 8 to 12 millimeters long that is surgically anchored directly into the jawbone. It functions as an artificial tooth root, providing structural support for a dental crown, bridge, or denture attached at the top.
Titanium is the material of choice for implant posts because it is biocompatible, meaning bone cells accept it and fuse to its surface in a process called osseointegration. This integration creates a stable, long-term foundation that can withstand chewing forces. Titanium resists corrosion in the mouth's moist, acidic environment and does not trigger allergic reactions in most patients.
Dental implant posts are typically made from titanium grade 4 or titanium alloy (Ti-6Al-4V, mixing titanium with aluminum and vanadium) in small quantities. Grade 4 is commercially pure and commonly used for its strength and biocompatibility. The alloy variant adds hardness and may be chosen when additional durability is needed, though pure titanium remains the standard in routine implant dentistry.
An implant post differs from other tooth-replacement options because it integrates into bone rather than resting on soft tissue or adjacent teeth. This makes it durable and functional, though placement requires adequate bone volume and a healing period of several months before the crown is attached. Chicago implant dentistry specialists assess bone density and patient health before recommending implant posts.
