To understand what a All-On-4 dental implant is, you first need to know what an implant is. A dental implant is basically a small screw that’s inserted into your jawbone in the space left by a missing tooth. Once the implant is placed in your mouth, your dentist will attach a fake tooth to the screw.
Now, multiply this idea by four and you get an All-On-4 dental implant. Instead of using an implant for every missing tooth, you can simply use four implants on top and four on the bottom as the main anchors for the whole row of teeth.
