All-on-4 / hybrid dentures are a set of dentures that are fixed in place with dental implants rather than with denture adhesive. These implants replace the roots of missing teeth, and they help anchor the dentures to your gums. The “All-on-4” name refers to the fact that you may only require four-to-six dental implants per arch for the treatment.
All-on-4 / hybrid dentures tend to be much smaller than a regular removable denture. A titanium core gives them added strength, and, with the help of a restorative dentist, they offer a full arch of natural-looking teeth to replace your original set of teeth.
