All-on-four implant-supported dentures provide an efficient and cost-effective solution for full-jaw tooth replacement. Rather than needing an implant for each missing tooth, this technique involves placing four strategically positioned implants per jaw to support an entire denture or bridge. In certain situations, depending on individual needs and bone structure, six or eight implants may be necessary. The all-on-four (and variants like all-on-six or all-on-eight) approach has gained popularity for its ability to offer a stable and reliable restoration of a full arch of teeth, providing patients with functionality and aesthetics similar to natural teeth.
