Answer:
A dental implant is an artificial tooth. The actual implant is a small metallic (Titanium) screw, that substitutes for the natural tooth root. It is inserted surgically into the jawbone, & it provides a stable base upon which a cap, bridge or denture can be anchored. But unlike dentures, dental implants may be fixed, feeling and acting more like your own natural teeth.
A dental implant is essentially a substitute for a natural root and commonly it is screw or cylinder shaped.
