All on Four

If you are having problems with damaged, unsightly, loose teeth or suffer with ill-fitting dentures or simply can’t tolerate wearing them, then dental implants can also be used to support ‘Hybrid Acrylic Bridgework,’ also known as ‘All-on-4’. This is the placement of four implants to the maxilla (upper jaw) or the mandible (lower jaw) then once the implants have healed and osseointergrated, Hybrid Acrylic Bridgework is screwed into the Implants as a ‘fixed’ replacement to a full arch of teeth.

This is a relatively new procedure, which replaces the idea that to support a full arch of teeth requires six or more implants per arch. The concept behind ‘All-on-4’ is that the posteriorly placed implants are placed at a 45° angle and this increases their strength and ability to support a fixed acrylic bridge. Thus the need for less implants to support a full arch of teeth.
