All-on-4 dental implants are a full-arch dental implant solution that uses four strategically placed implants to support a fixed dental prosthesis, replacing an entire arch of teeth. The All-on-4 technique uses four implants, with the two posterior implants placed at an angle, maximizing contact with the jawbone. This provides a strong foundation for the dental prosthesis, which is secured to the implants. All-on-6 technique uses 6 dental implants, providing even more stability.
